Invalid color

RErender - yeah, i learnt to know that those warnings are meaningless if you're happy with the results.
however - when the warnings come hand in hand with some annoying neon spots all over my scene, i tend to take them seriously. any idea about that problem of mine, three or four replies up the stack?

[RErender]

noam_farhi- Hard to pin it down without images/settings but the usual suspects are:

Raytrace materials
uncropped bitmaps
double faces
out of scale model

What changes have you made since it rendered corectly?

[rhino]

Rerender, what's the uncropped bitmap problem?

[RErender]

Been a while since Vlado explained it, but if I remember it was something like Max returning illegal values for the edges of bitmaps which is fixed by applying cropping. Vlado has since said that he has rewritten the bitmap handler to fix the problem but needs Discreet to authorize it ...

I have written a script to apply cropping globaly www.varcht.com/tools.htm

Thanks for the explanation and link.

[Psy]

you taking any requests on scripts to write rerender?

[RErender]

Nah, but I am working a new one to set interpolation values globaly, need to work out how to save out settings.

[jsr]

The crop script didn't help me with my scene. But setting clamp = on at the bitmap output options helped.

Why don't you make an option for vray to force both clamp and crop on at render time?

[jsr]

Actually the overbright message seems to be quite random with my scene. What I did was:
- set the clamp on --> render OK
- add a falloff map to the glossiness map slot --> overbright, render not OK
- remove the falloff map from the glossiness map slot --> overbright, render not OK

Is there no way of scaling down the overbright values automatically in the renderer?

[jsr]

Yes, it's random. I saved the scene that caused the overbright material and closed max. Then I started max again and loaded the just saved scene. And, wow, render OK.

It would be helpful if there would be some more info about what is causing the overbright material, for example the material name.
