Web9 de jan. de 2024 · Hi ! I have some issues with batching my sprites. I created two VBOs, one that stores UV (2 floats per vertice) and the positions (2 floats per instance) and another one that stores the sizes (2 floats per instance). Positions and UV are supposed to change a lot because they are moving sprites. I also have one vbo which represents an … WebWhen drawing with one of the instanced rendering calls, gl_InstanceID is incremented for each instance being rendered starting from 0.
