this is my problem:
i have n meshes stored in a vbo. The meshes have the same structure ( same number of vertices ). So i need only one array of indices and specify an offset for each mesh. glDrawElementsBaseVertex seems what i am looking for but i need to make a call for each mesh. Instead i want to make ONE call to render all meshes. I want a kind of instancing but not for rendering one mesh n times but for rendering n meshes with one index buffer with different per-instance offset.
Is it possible?
