<div dir="ltr"><div>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?<br>

<div dir="ltr">Hi,<br>
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?<br>
<br>
I have no idea is this is practical or possible within GEM
setup, but if it is - any interest in adding this function?<br>

Hello,<br>
<br>
You can't pass individual uniform values to each vertex.<br>
I guess you try to pass individual values to each vertex. For this
purpose, you can use attribute variables.<br>
You are limited with the VBO object of Gem to use "build-in" vertex
attributes : position, color, texture, normal.<br>
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.<br>
