The way I understand it, drawRanges can be used to draw a subset of elements. I know with drawRanges you can specify the number of instances to draw of a given element range, but I'd like to be able to be able to draw all elements for a given subset of the drawCall's instance attribute buffers. Is there something like drawRanges but for instances?

Looks like this could be possible using the WEBGL_draw_instanced_base_vertex_base_instance extension
