Odd error with GLSL in VS with 6800
I am trying to check for a height in the VS like this
and I get a compile error in RenderMonkey and my code. The code above is the problem and once removed it runs fine? Any ideas thanks... Oh if I remember right it runs fine on my ATI card.. :(

Well what's the error??
Well as of now I am now away from my desktop so I can't look it up, but I am on my laptop with the ATI card and it works fine...
code on ATI
//VSvarying float temp; if(gl_Vertex.y <= .02) temp = gl_Vertex.y;

.02 to 0.02. That could be the problem...
Hmm not sure why that would be, but I can try it once I get back to my desktop.

Neither am I, but it's the only thing I see wrong. Why is RenderMonkey not giving you an error on your ATI but not your GeForce? Or what error are you getting? (List specifcally please)
ATI's GLSL compiler can be a bit picky. Make sure all numbers are correctly formated and of the correct type... i.e
float * int
on a Nvidia will compile but will fail on an ATI (in my experience)

Not to be rude, but my post stated my ATI version works. ;) The Nvidia is messing up. I will later today try them out and get the error RM is spitting out and post it. But thanks for everyones help so far...
I suffered a lot of weird behaviours from RenderMonkey too...have you tried changing that ".02" by "0.02"?...believe it or not, it can make a difference...
I have an ATI 9700Pro and use to get lots of silly error messages like that one

Ok, I tried the 0.02 and no dice. Here is the message in RM, mind you this code is 100% same as the ATI code I am using and the ATI card runs fine.
