Invalid color

[Smalerbi]

Could someone please explain to me what this is and what it means? I've been getting this from time to time and I think is causing some rendering artifacts.

Thanks,

Scott.

are you doing interior scenes ??
basicaly it means the materials that are getting this message are over bright.
try lowering your light settings ?
but if its not affecting your renders, dont worry.
its only a warning not an error.

Yes, it is an interior scene and I am getting a few small white splotches sprinkled through out the rendering. I will try to lower the light settings......stay tuned.

Thanks

give everything a thickness aswell.
oh ....and keep the second bounces below .6
why dont you post your settings.

That doesnt mean a error, only a warning that you are using higher color values than 255. This is normal when a HRDI map is used.

my thoughts exactly Gonçalo

That seemed to do the trick. I had the second bounces set to .85 and I reduced it to .58. I'm still getting a few of the over bright warnings but the white splotches are not longer there.

Thanks.

Re: Invalid color

hey scott
i had a similar problem - i got many of these warnings and some neon colored spots all over my scene.
i didn't use raytrace materials or HDRI, and my secondary bounce is set on 0.5 . the lighting used to be fine too, and i didn't change it, so i doubt it's an overbright light.
other files renders fine, but previous backup files of the same scene (which used to render fine) also get the same problem.
any idea from your own experience?
thanx

noam_farhi its possible that your old scenes are using old materials and since the material for vray has been changed over time there might be some incompatibilities. not sure though

I'm very new to Vray but I will give it a shot. On one of my scenes, I found out that it was specific item (geometry) that was causing the problem of the neon spots. After removing it, the problem went away. I do not know if that helps.

Re: Invalid color

right, this sounds really weird to me, but maybe one of you guys would see the logic behind that:
i checked my geometry, and it's probebly not the problem - since we're talking about a scene that used to render fine, and then didn't, without me changing anything (surely not geometry). BUT, i noticed that if i open an older version of the file, made many changes ago, render it (it always render ok), and then open the new one - in renders fine. that's really odd.
i thought maybe it has something to do with the "incremental add", but i also tried "single".
does this make sense to someone? please share your thoughts...
thanx for the replies

On the topic of warnings, what does this mean?

warning: HDRI map locked, not loading

[noam_farhi]

i don't know, but i get that one whenever i use HDRI but i see no problem with the results, so i live in peace with it now...

I think the problem here is the word "warning" seems to have a negative conotation with most people, might be better if it was something like "attention" or "info" or ... the hdri thing just means that it is already in memory and does not need to be loaded again.
