Hi Edmond, How many matrices do you need at any one time? There is a limit to how much vertex attributes, uniforms and texture matrices you have available.

Hi Robert, thanks for pointing out this possibility. However, I need to pass relatively large amounts of matrices to the vertex shader (between 50 and 10000, even more), representing reallly complex skeletons. Maybe another solution would be to map the matrix array into a RGBA texture and then access it through a sample2D variable. The advantage is that relatively small "textures" can represent a large amount of matrices, i.e. a 256x256 RGBA texture could hold 16384 Matrixf. In order to not waste space, I could use non power of two textures. Do you think it's a viable solution ? Is it possible to create Texture1D raw non-power of two textures ?
