ColorCorrect plugin can cause shading problems

[vlado]

The ColorCorrect plugin can cause shading problems with VRay (red dots, bright spots etc). This seems to be because of bugs in the ColorCorrect plugin itself and is not a VRay problem specifically.

This was tested with version 3.0.3.6 of ColorCorrect.

thats the most painful post I've read in a while.. is there any hope of a workaround or fix?

[vlado]

Well, I've sent an email to Cuneyt Ozdas - if there is anything that can be done, he is the one to do it...

Darn, CC is one of the most useful plugins for Max.

hmm, I've been using CC w/ vray on different projects w/ lot of maps affected by CC, and so far I haven't had any issues........but thanks for the warning....hope things will keep going the way they are (crossing my fingers)

I suppose it may be happening only with HDR images, but I'm not sure...

You can try this: Take a standard material and put a noise map in the diffuse slot. Then two colorcorrect nodes on top of the noise. The lower one with contrast 400 and the colorcorrect on top with gamma >1.

Standard material
diffuse:
colorcorrect (Gamma >1)
+--->colorcorrect(Contrast 400)
+----->Noise

And it's red (also with max scanline renderer).

I believe this is the second time an issue between VRay and CC has occurred, its so annoying specially as i use it alot.

color correct is strange...it looks like a great plugin but it doesn't work as i expect it.
especially the hue/saturation controls are confusing.

Is this CC issue solved in the current Vray RC2 Version ?

[RErender]

IT is CC that is broke, not VRay . Basically it works, just if you try to tweak a map too far you can have issues.

Yeah, one time I tried to turn a map of reddish tuna into a green garnish with color correct... apparently I'd gone too far, overbrights were everyyywhere.

Another note about using CC with HDRI maps -- I've had problems, but have successfully been able to hue-shift them using HSL space. I've found that if I have RGB space ON, even with no adjustments made, VRay freaks out and takes a loonnggg looongg time to calculate the HDRI.

also, the saturation does not work at all.

I downloaded the latest build from Cuney Tozdas' site, no guarantees, but it past the test given on this thread for non HDRI images...

ColorCorrect_v3.4.86.9_x86

Max 9, V-ray 1.50.00

I've been using it for a while now, with both Max 9 and Max 2008 in combination with VRay 1.50.00 and 1.50.17 but haven't had any problems. So I guess it has been fixed over the past three years :P
