Hi.

Ive recently changed my shaders to use only generic vertex attributes instead of the built in ones. I got everything working fine but yesterday when i updated my graphics card drivers my game stopped working. I then ran it on my other PC that was always capable of running the game and it also crashed in the same way. I went and tested it on more PC's and it crashed on some and worked on others.

I cant get an proper error message back from opengl. I use java + lwjgl and i know that sometimes when i do something realy bad it crashes the entire JVM making it effectively impossible for me to track the exact cuase of the error. (well there might be a way in which case i just dont know about it)

Im taking a guess that it might crash on some PC's becuase i never call glDisableVertexAttribArray since i thought it wont be neccesary but i might be wrong. So my question is: When should i call it?(if ever) and when should i call glEnableVertexAttribArray again?

currently i just enable all vertex attribute arrays once when the game starts up and then i leave it enabled.

Thnx in Advance!

So unless you're using the same VAO for different objects with cases that don't require certain attributes, I don't think you need to disable arrays. You are using the new GL 3 API right?

I have more than one shader. And not all of them require the same vertex attributes, does that mean i should disable the vertex attributes i dont need when switching to a diffirent shader? For example the shader i use to render 2D objects doesnt require vertex tangents like my 3D shader.
