The subject line says it all really, I just assumed that you could use more than 1, but I can’t get it to work with more than one in OpenGL ES 2.0. I thought that maybe for fine-grained sharing over multiple draw calls, using more than 1 VertexArrayObject would be useful, but I can’t think of a particular use case right now.
Can it be done?
No, there can not be more that one VAO bound at the time. That is the purpose of VAO – to simplify binding of vertex attributes just with the one call. If you want more control on individual attribute binding then don’t use VAO, just bind the vertex attributes individually.
