Hi Edmond, I don't know fully what you are trying to do so I can't really advice the best route. I don't have time to spend understand the intricisies of what you doing so I'm afriad you'll just need to experiment and learn as you go along.

Hi Robert, I need a 4x4 matrix because I need to translate and rotate tree stems. However, I am still considering which solution to choose: 1. simplify the model, pass the 4x4 matrix array as a uniform array and the matrix index for each vertex as an attribute. 2. passing the 4x4 matrix array as VertexAttrib using VertexAttributeIndices (then no fast path allowed) 3. using quat and translation vector instead of 4x4 matrix and pass them as VertexAttrib using also VertexAttribIndices (still no FP) I think that the best solution is the first one, since it allows the fast path to be used and doesn't need to convert matrices into pairs of vec4's... I am certainly missing other solutions, but it is the first time I run into this kind of application. What do you think ?
