Hello I just started using Ziva and have a question about ZMaterials vs ZFiber. I opened up the Ziva Examples for the Anatomical Arm, and it has be incredibly helpful however I am confused on the topic of ZMaterials. Looking through the example. I had tried to paint the ZMaterial weights on the muscles, however it doesn't seem to be working, and my weights are not being saved. Now the question I have is that through using ZFiber is it possible to still have ZMaterials maps for extra control? or is it rather just choose between ZMaterials or ZFiber, but then why would there be both nodes in the example, i'm pretty confused on the functionality would appreciate some extra clarification. Thanks!
