i have a feature request that will solve a lot of headaches…
Blendshapes
Solving Meshes, This process solves half of our problem. We need to align the texture points , since during the projection process you cant keep the texture points at the same space in the uv, we need to post process the texture, otherwise, when you perform a blend between two facial expressions, you will get a “fade” effect in you difuse / normal, thats occours because your texture are not aligned perfectly… we need to perform an optical flow calculation to find the offset between those points (for the entire texture) and then apply these coorections to the mesh…
Hello! That’s an excelent point and we are working on the optical flow tool.
Here you can see our early test: https://drive.google.com/file/d/0BxeSaP5E4JfvQmNQdm9VTC1qZms/view?usp=sharing
Please download the video for better quality. However this approach requires too much user interaction and we are working on making it much more robust and automatic.
The solution in the video is not the best one, it still requires a lot of hand work. We do have a private test application of the old solution but it’s really painful to use. The new solution should be much robust and requires much less user interaction but we are only at the beginning of development.
Hey, we are very close to release of OpticalFlowWrapping node. You are welcome to participate in beta-testing, I’ll send you instructions in PM in a minute.
