Reflection map not working in LIVE LINK, upon further investigation I've uncovered some stranger things

[Yurgen99]

Found a very odd bug with live link and corona: (see images)

Simple reflective material with a reflection glossiness map - works perfect, but as soon as I apply a diffuse it loses its reflection map



Diving a bit deeper into this:

• If I apply a corona colour with white (or something light) into the diffuse it overrides the reflection map entirely and gives a perfect smooth reflection!
• If I apply a corona colour with black or something dark I get no reflection, (or half (semi reflective) if I were to apply grey).
• I'm pretty sure if we also apply a light picture into the diffuse we will get some reflection where the light parts are.

Somehow the diffuse slot is hijacking the reflection?

- - - - This only happens when using live link, If I export to vantage from corona (without using live link) all reflections are correct. - - - -

See attached images, I did some tests. I have kept exactly the same dirty/smudgy reflection glossiness map throughout.

Is this a known bug? just me?

• I tested in a fresh max scene when I noticed it happening in other scenes.
• I've tried using corona phyiscal material - same issue
• Im using corona 12 hotfix 1, MAX 2024 fully updated, Win 11

Thanks for any help, really excited to use live link as I love vantage, just confused why this is happening.
