Right - attribute not uniform. The texture table is a good candidate for non-texture VBOs - 8 parameters from the UV coordinates. Otherwise probably the color table? (4) - as color is usually determined in the shader or from the texture itself?

Hi, I'm trying to find a way to get each vertex in a VBO to send individual uniform values to a connected shader. I was thinking it might be possible to send these through an unused table... or maybe a 5th table could be created (length given with msg) to be referenced by the shaders?
I have no idea is this is practical or possible within GEM setup, but if it is - any interest in adding this function?

Hello,
You can't pass individual uniform values to each vertex. I guess you try to pass individual values to each vertex. For this purpose, you can use attribute variables. You are limited with the VBO object of Gem to use "build-in" vertex attributes : position, color, texture, normal. If you want to pass individual values to vertex, use one of this "build-in" vertex attribute that you don't use and get the attribute in your vertex shader. ++
