I’m curious about if there’s a reason read/write isn’t automatically enabled on meshes. I don’t mind having to turn it on but I just want to know if turning it on makes load times longer or something.
When read/write is enabled on a mesh a copy of all the mesh data needs to be present on CPU memory. This is wasteful if it’s not going to be used. So if it’s not needed, the mesh data is uploaded to GPU memory for rendering purposes and doesn’t need a copy in CPU memory.
