Rhino 6 - Lighting turns pink/magenta

Quote from ana@bca

I'm trying to render with Enscape from Rhino 6. When I model lights by using lumens as the unit all of the shadows turn magenta. I'm trying to render with accurate light measures and everything turns pink. When I model with "Default (Scalar)" everything looks normal.

That is an interesting behavior - is there any chance you could briefly send over the project file? We have not seen anything like this before. Also, welcome to our forum!

Looks like the same pink color at this issue here:

Strange pink light

Thanks a ton Micha , good memory!

ana@bca , if possible, you can happily check out the linked thread from Micha to see if this may be related? In any case, you can feel free to also send us the project instead / additionally.

Also having this issue with an older rhino model.

Not sure if its relevant, but it was originally set up with Vray materials.

I even tried copying the geometry (none of the lights) into a new file, and adding new lights.
Still, the same issue persists, even in "White box" mode, all shadow / reflections are pink.

Lights are set to 100% pure white. Walls, floor are generic white material.

SkipFifth , do you experience this behavior in our latest release as well? I can see that you're still using a previous release of Enscape at the moment.

If an update doesn't help, is there any chance you could share the project with me?

Check if you layer color is pink. In one of my studies the layer colours were kind of affecting the gi

The organization I work for controls software updates, and is not yet giving us access to 2.6+

That being said, I did find out it is related to the lights, and not to the layer colors.

I was able to take a new file, paste in just the walls and floors, and get normal results.
After pasting in even just one light from the 'original' file all the GI turns pink.
Then, even if I delete that one light, the GI stays pink like in the image above.

So, by copying over everything but the lights, and doing the lighting from scratch, i was able to resurrect the file.
