Re: [osg-users] Reason why not to change the name of a Uniform?

Hi Robert, thanks for your answer. I agree with you for most applications. Now the thing is, we are currently adding a simple text-based Shader Editor in our application. So while writing the shader the developer will change uniform names almost for certain. Now the developer will not
