I’m trying to load the model and do cloth simulation on it. But I find that the loaded model(fbx file) has no attribute index(using FBXLoader). And I need the ‘index’ to do cloth simulation.
Moreover I find that all the loaders integrate the ‘position’ and the ‘index’ attributes in original file into one called ‘position’ when loading and just use ‘position’ to render the model.
So i wonder if there is any way to load model and reserve the attribute ‘index’ or there is any way to compute the ‘index’ on the loaded model. Thanks.
