Fedor Posted June 7, 2017 Share Posted June 7, 2017 As far as I understand, updating the positions data on a mesh using updateMeshPositions - or other update* functions - only works when the mesh is set to be updateable. This setting can only be done at creation time. All basic shape creation* functions have the updateable option that can be set, but the standard mesh constructor has not. How do I make a custom shaped mesh updatable? I have thought of a workaround, by creating an updateable cube or something and replacing the vertices data with my custom mesh data. I have not tested this, but I will. And another question: it was my take that the updateMeshPositions is the fastest way to update the vertices positions. setVerticesData works also on non Updateables but seems to be slow. Is updateMeshPositions the fastest way to modify the vertices positions? And if not, what is? I am working on a sculpting app, my custom mesh has over 50K positions. Updating vertices is what the app is all about and I need it to be done as smooth and realtime as possible. Quote Link to comment Share on other sites More sharing options...
