bdunaway Posted October 4, 2012 Share Posted October 4, 2012 So I've got a heart model with the faces 'growing' over time. It has a subsurface scattering shader using the new Surface Model node. It works great, but when the model is still in the growing phase, there are dark spots which I assume are due to the rear holes in the model affecting the subsurface calculations. I wrote out a point cloud file from the full model, but that didn't help. Where can I go from this point? Baking lighting / textures or something? Is that even possible with SSS?

abvfx Posted October 5, 2012 Share Posted October 5, 2012 When you say you wrote out a point cloud for the whole model do you mean a point cloud for every frame of animation because that is a sure fire way to make sure everything works.

bdunaway Posted October 5, 2012 Author Share Posted October 5, 2012 (edited) I wrote out one to file from a single frame only - the one of the full model - because I thought that might fix the artifacts, as I'm pretty sure they are caused by the SSS calculated from the incomplete model. It didn't change anything in the render though, I get the same result as when it was calculated point clouds every frame be default. Here is a video of it if that helps: Edited October 5, 2012 by bdunaway Quote Link to comment Share on other sites More sharing options...
abvfx Posted October 5, 2012 Share Posted October 5, 2012 Have you tried using a polycap node to cap any holes, and then set those faces to invisible. I kinda had this same problem and it cleared it right up. Quote Link to comment Share on other sites More sharing options...
