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

    ​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.

      You have to ask the Corona guys, they are developing the Corona to Vantage export and live link.

        It could be a bug, we will check. You could also post such topics in the Corona forum because usually the issue is in the Corona->Vantage/VRay translation layer. I've forwarded to the Corona team.
