Spiros tutorial: Morphing spirals

In this tutorial we are going to explain how to make a transformation animation (morphing) between 2 shapes created with Spiros.

At Spiros‘ introductory video, there’s an animation in wich a spiral shape morphs into a spherical helix that becomes the Earth globe (see the image above). That animation was made in 3dsMax with a little used technique: using the Morpher modifier to morph between splines.

This modifier is very powerful and it’s capable to make transformations not only between 3D meshes, but also between splines (and FFD lattices). The only restriction is the same as for meshes: splines must have the same number of vertices/knots.

Since Spiros let you set a specific number of knots for the shapes you create or modify, you can make any transformation between any shapes created with this script. Just make sure they have the same number of knots. Also consider to change the order of the knots in the spline (reverse it) if necessary, for getting a better result.

The better way to make this kind of morphing is to work on a single channel in the Morpher modifier. Just add all the shapes that will participate in the transformation to a single channel, then arrange the order of appearance and adjust the tension parameter to zero.

Try ity! There’s a lot of cool animations and effects you can do by morphing splines. Imagine you have many objects whose position or rotation depends on a path (path constrained) or they are wrapped to a spline (path deformed). If you animate (or morph) the spline, they will act in consequence. It’s an incredible tool for Motion Graphics animations.

That’s all for this tutorial. I hope you liked it and make great animations.

Spiros tutorial: Making jewelry

In this tutorial we will learn how to model some ornaments, based on spirals and torus knot shapes, to make jewelry objects.

First, we’ll see how to create a bracelet with a triangular spiral shaped decoration. Secondly, we’ll learn how to make two different kind of pendants from torus knot shapes.

Before starting, let’s see which are the most common methods in 3dsmax to turn a spline curve into a volumetric mesh:

  • Make the spline renderable (Editable Spline properties)
  • Apply a Sweep modifier
  • Use Loft compound object
  • Use Path Deform modifier
  • Extrude Along Spline (tool from Editable Poly)

In this tutorial we use a different method for each of the three cases, but you can use the method that better fit your needs, or the one you are more comfortable with.

Making the bracelet

As you see in the image above, the bracelet’s triangular decoration was made starting with a simple spiral object created with Spiros.

Here’s the process:

1. In 3ds Max, open Spiros and create a spiral shape on the top viewport, with the size you like.

2. At the script’s UI, set the following values: Turns = 4.0; Knots = 13; Curve type: Line.

3. Now you will have a triangular spiral. Rotate it so that the triangle points upwards.

4. Edit the spline as shown in the image, to make all the sements perfectly parallel and delete the extra segment on the left.

5. Add a Sweep modifier. Use the built-in section called “Half Round” as the profile shape. This will turn the spline into a volumetric mesh.

6. Adjust the Sweep radius so that the mesh does not overlap itself, until it looks similar to the image.

7. Convert the mesh to Editable Poly to clean the geometry, remove undesired parts and add detail wherever you like.

8. Subdivide the mesh or add tesselation to increase the mesh resolution for applying later deformation.

9. Model the tube for the bracelet.

10. Place the triangular mesh on top of the tube and apply a Bend modifier to make the triangle conform to the tube’s surface.

11. Add any necessary details to finish the bracelet, apply materials and you are done!

Making the pendants

Celtic Knot

The first pendant, a celtic knot similar to a flower with 4 petals, was made the following way:

1. In 3ds Max, open Spiros and create a torus knot shape on the top viewport, with the size you like.

2. At the script’s UI, set the following values: Foils = 4; Variant = 2; Star/Ring = 6.

3. Scale down the shape in Z axis to make it flatter.

4. Create a rectangle shape to use as the profile section.

5. Apply an Extrude modifier and make a very tall box, with 100 segments for starting. (The advantage of this method over using the Box primitive, is that you can set the number of height segments to a very high value)

6. Apply a Path Deform (WSM) modifier to the box and pick the torus knot as its path. Press “Move to Path”.

7. Go down in the modifiers stack and adjust the Rectangle dimensions to give the knot mesh a reasonable thickness and proportions.

8. At the Extrude modifier parameters, adjust the Amount and Segments until the knot looks closed and with a nice mesh resolution.

9. Zoom in the part of the mesh where the start and end of the knot meet. You will need to make both ends of the mesh match perfectly.
For that, go to the Path Deform modifier and adjust the Twist amount.

10. With 3dsMax snapshot tool, take a snapshot of the mesh. Then convert it to Editable Poly.
Now you can delete or hide the old mesh and path. You will work with the new object now.

11. Weld the start and end of the mesh. Perform some cleaning if necessary and then model any extra details you desire to finish the pendant.
Apply materials/textures and you are done!


5-Pointed Star

The making of the second pendant, a 5-pointed star (or pentagram), will be explained very briefly because the procedure is very similar to the previous objects.

1. In Spiros, draw a torus knot with the following values: Foils = 5; Knots = 5; Curve type: Line. (or choose 5 Point Star preset from the dropdown list)

Tip: You can make Star shapes with the Torus Knot tool by setting the same number in Foils and Knots, and set the Curve Type to line.

2. At the spline parameters, make it renderable in viewport and renderer. Set the section shape as Rectangular and adjust its dimensions as desired.
Now you have the star mesh.

3. Convert it to Editable Poly. Perform some cleaning and then add the necessary detail to the mesh.

4. Model the ring to complete the pendant and then put both pieces together. Apply materials/textures and you are done!

How to get interesting splines to feed TurboSplines

There are many ways to get appealing spline curves to work with in 3ds Max.
Here’s a bunch of ideas to boost your imagination:

3dsMax parametric shapes

The standard parametric shapes of 3dsMax are generally not interesting enough to make nice splines for animation. However, with a little of creativity, you can get very nice-looking curves from them.

For example, a combination of overlapping circles or concetric circles arranged to fit a specific design or porpose can make an outstanding animation with very little resources.

Another powerful method is to use text shapes with interesting typography. Just convert them to splines and add some fillet on the corners to get a smooth deformation when using TurboSplines.

Import them from vector software

You can design your curves using a 2D vector software such as Adobe Illustrator and then import them into 3dsMax.

If your splines are imported with a lot of unwanted knots, gaps and other common errors, you can use our great Spline Cleaner to clean and repair them easily.


Natural and harmonic movement is an amazing source of beautiful splines. 3dsMax comes with a tool to convert any trajectory to a spline (see the Motion Panel). So if you already have animated objects or characters in your scene, use them as your source of splines.

If you want a tool capable of extracting trajectory splines from many animated objects, bones or even particle systems, try our free script called Trajectory to Spline.

Edge Loops

Meshes with a smooth surface and clean topology are also a good source of splines. You can select edge loops that surround the mesh and use the Create Shape from Selection tool from the Editable Poly parameter interface.

Some 3dsMax primitives, such as the Torus Knot (in Extended Primitives) can produce mathematically perfect and beatiful intricate splines.

Shape sections

Another way of extracting splines from meshes is to perform a cross-sectional slice through them, using 3dsMax’s Section Tool, located at the Splines creation section.

Plugins and scripts

There are a lot of nice plugins and scripts for making gorgeous splines. Many of them are free.

Go to and make a quick search in there. You will find plenty of useful spline generators.

A great tool for this our SuperHelix Free. Try it!

Draw your own splines

Of course you can draw your custom splines directly in 3dsMax. Just make sure they flow smoothly through your scene’s space.

You can use the Array tool to make interesting arranges of splines if you need to.


That’s all for now. If you have specific doubts or consultations, you can contact us through the contact form or leave us a message at our Facebook Page. Cheers!

TurboSplines: Quick Start Tutorial

Welcome to the wonderful world of TurboSplines! 😉

With this quick start tutorial you will learn how to work with this script and begin to familiarize yourself with its tools. For that, we will create a simple scene with some growing splines.

You can access the following image from TurboSplines Help section, clicking the Quick Start Tutorial button.

The instructions in the image guides you through the typical steps required to create a “growing splines” animation.

These are basically the steps to follow, even simpler:

  1. Draw or prepare your splines (they will work as paths for Path Deform modifiers)
  2. On TS Creation section, go to Source Paths area and load your paths. They will be listed there.
    (The steps 3 and 4 in the image are not necessary for this example, but you can do them to learn a little more about TurboSplines tools)
  3. Press (RE)BUILD GEOMETRY button. This will create one path-deformed cylinder for every spline. They will look the same as if you created renderable splines. The big difference is this way you can make them grow!
  4. Go to TS Edition section and change the Radius parameter to adjust the width of your meshes as desired.
  5. Go to TS Animation section and change Animation Type to GROW (stretch).
  6. Finally, press CREATE/MODIFY ANIMATION button (at the bottom of the section).

Now play your animation and you will see your cables growing.

This is just a quick sample of the power of TurboSplines. Play a while with all the script parameters and you will be able to make your scene and animation as complex as you like.

Maybe at some point of this tutorial you wondered this: why can’t I directly animate my renderable splines??

Well, here’s a good news: you can! 🙂

The porpose of this tutorial was to show you an overview of TurboSplines’ workflow, but if you only need to make growing splines, there’s an extremely simple way to do that:

  1. Just start directly with your renderable splines.
  2. With your splines selected, go to the TS Tools section and press Convert from Renderable Splines.
  3. Go to TS Animation section, set the Animation Type to GROW and finally press the big button at the bottom to create the animation.

You we’ll get the same result in less steps, leaving to the script only the animation part. Then you can modify the meshes with TurboSplines since they will be now TS meshes.

We hope you enjoyed TurboSplines. Check out the other tutorials and videos for further learning.

Spline Cleaner: Quick Start Tutorial

Welcome to Spline Cleaner, a set of powerful tools for cleaning, repairing and organizing spline curves in Autodesk 3ds Max!


Spline Cleaner UI1. Unzip the content of the .zip file and then drag the “.mzp” file onto one of your viewports in 3ds Max . The script automatically installs itself.

2. A dialog called “Software Activation” pops-up. Enter your license key in the text field. (You received 2 license keys by email when you purchased the product).

3. If the license key is correct, Spline Cleaner will start.

4. To add the script to a toolbar, go to the Menu > Customize > Customize user interface…

5. Go to the “Toolbars” tab and pick the category “Spline Dynamics”.

6. The script’s name, “Spline Cleaner”, must be listed there. Just drag it onto a toolbar and you’re done!


This script comes with an interactive tool called the Splines Info Dialog, wich displays very useful information about the selected shapes/splines.

We strongly recommend you to keep this dialog open everytime you manipulate spline curves to have an instant feedback about their changes.

  1. Draw some splines and shapes  in your 3dsMax scene.
  2. Convert them all to Editable Spline (most of Spline Cleaner operations requiere Editable Splines to work. Otherwise you’ll get a warning message)
  3. Select the splines and open Splines Info Dialog (the topmost button).
  4. You’ll see there all the splines info: no. of shapes selected, no. of splines, segments, vertices, spline length, and more.
  5. Click the button Show/Hide Vertex Ticks to display all the spline vertices/knots.
  6. Make changes to the splines, add, delete and move vertices. Then re-select the splines or change the selection to update the splines info.

This tool can also make a diagnosis of possible errors on your splines, such as overlapping duplicates, double splines, overlapping vertices and empty shapes.


If you scroll down the script’s interface (UI), you’ll see there are more tools and other rollouts.

The main tools are in the first rollout. In the rollout named More Tools there are some complementary tools, such as Flatten Splines.

In the rollout Basic Parameters, you will be able to change the basic parameters of all the selected splines at once. Try it!

On the right of every tool’s title there’s a question mark icon. When you place the mouse pointer over this icon, a tooltip with help appears. If you click it, in most of the cases, a dialog pops-up showing an extended help.


To start trying the script, you can play arming and disarming shapes with many splines. You can do it very fast with Spline Cleaner.

Draw some shapes and splines and create some duplicates to have a bunch of curves. Use the tools Splines Info Dialog, Attach Selected, Explode and Weld Vertices to see how powerful this script is.

We hope you enjoyed Spline Cleaner. Check for more tutorials on this site!
