Displacement map breaks round edges

Recommended Posts

Hi, I’m importing an object created with Shapr 3D (an iPad Pro CAD App) into Cinema 4D and applying a noisy displacement map to it with a Corona Renderer material. For some reason it breaks the material, but only at round edges. I’ve already tried it with different file types, import options and also with other models, but the problem still occurs. The team from Shapr said it's  probably because the rounds are G1 continuous and that they don't support G2 continuous fillets currently.

I attached a screenshot of it.


It would be really nice if someone could help me fixing this problem 🙂

I think you can use a bump or normal map for this look because I don't really see any deformation of the contour shape.

It will also render faster and should fix the problem with the distortion of the round edges.

If you use a 3D noise you don't even need UV's.

Change texture projection to cubic instead uvw, and tweak texture scale.

  • Thanks for the recommendations, I will give it a try 🙂 ... 


    A first test with only using bump seems to work!
