Hello,
I am trying to update the position of vertices at every frame for a properly constructed triangle mesh constructed with NvFlexCreateTriangeMesh() and updated with NvFlexUpdateTriangleMesh() (See docs [url]FLEX: NvFlex.h File Reference
Every works perfectly if I create and update my triangle mesh ONCE during construction but I get CUDA errors 4 in ‘cudaMemcpyAsync’ when I try to call NvFlexUpdateTriangleMesh{} during the update frame.
I have tried shifting my per-frame call to NvFlexUpdateTriangleMesh() at different times relative to per-frame Flex pull-from-GPU, modify structures, push-to-GPU but nothing works.
Q1: Can triangle meshes have their vertices updated once a frame?
Q2: If so, when can I update?
Q3: What memory flag do I use? (Host, HostAsync, Device, DeviceAsync)
Many thanks for any clue you might have… grasping at straws for days!!
Daniel,
