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. ++ Jack
