Material does not display on viewport - ****BUG**** Corona Render 12 HF1

[Alex Abarca]

When a CoronaSelectMTL is applied to a decal it does not display material preview in the viewport. Even when the "Show Material Preview" is checked. Please try this on your end this is easy to replicate.

I tested this with CoronaLegacy and CoronaPhysical

3dsmax 2024.2.1 Update
Corona Render 12 hotfix 1
AMD Threadripper
RTX 4090

I also tested with:

3dsmax 2024.2
Corona Render 12
13th Gen Intel(R) Core(TM) i9-13900K   3.00 GHz
RTX 4090

I can also confirm and want to report this with Corona 11 HF2.
The CoronaSelectMtl viewport preview does not work, not only with decals but also with simple meshes.

On the other hand, CoronaSelectMap works without any problems, even when nested within each other.

What's interesting is that when I select CoronaSelectMtl, I can't even activate the "show shaded material in viewport" option. This button is only active when I select the linked materials.

Please look at my attachment.
Best regards
