Blue-Shift when Previewing Materials w/ transparent BG in SME

[Anonymous]

My issue is when previewing Arnold Textures in the SME [slate material editor] in Max18 [3DSMAX 2018].

Here is a video showing the issue https://youtu.be/cqS7bf96kjw . Please don't take the joke in the title seriously, I always wondered if I'd be butchering the ethos here with a joke that's probably a revenant ghost by now.

There's not much to it. I make an arnold material, I make the preview background the standard Max checker pattern, then the preview object suddenly has a blue haze.

My workaround for this currently is running a second instance of 3ds Max with the just materials and spheres loaded in. I then hide and show checker backgrounds in actual physical scenes to rapidly prototype the look of a material.

Thanks for your time I look forward to hearing from the Arnold community about this 🙂

I use a custom background to fix it. 😉

Still having the same problem in MAXtoA 2.1.945.

Having the same problem here. Using 3DSMax 2019 and MAXtoA 2.1.945.

Changing background does not solve the problem.

It appears to take the color of the upper left pixel of a custom texture to light the material preview.

So I added the same gray as the default background of the material slot,~50 percent grey.

Here is my test background:

I tried it, but although the blue cast goes away, the reflection and refraction still not be seen.

This is a known issue and we have a ticket for it. We'll try to get it fixed ASAP.
