I’ve finally designed what I wanted using a bump map. Turbosplines is a super program, though it wasn’t the exact tool for what I wanted.
I used the file from the CNC, inserted into Adobe Illustrator and used the paths with 2 layers of brushes with different blurs and opacities. Then I exported to png, I fine-tuned in Photoshop and used in 3Ds Max as a bump map with correct UVW Mapping.
The result is attached. I wanted to recreate this door for the same company:
Overall, even though I used another method to produce my 3d still images, I give Turbosplines 5 stars, excellent product and superb feedback from the creator Hernan A.
Congratulations and thanks a lot!
