We are about to switch to a new forum software. Until then we have removed the registration on this forum.
To create an effect, I need some extra values associated to each vertex, then I would like to define an extra vertexAttributes with my values stored inside.
I saw the LowLevelShader example. It works but if I follow that exemple, it needs to define every vertexAttributes by myself and that's not what I want... I would like to add a custom vertex attribute to the "vertexAttribute-list" not to create all the list...
How can I do that ?
If there is no solution, it's possible to "hack" Processing structure and use "tint" or "normal" to send some values to the shader, but it's really not my favorite solution :)
