Strange bug with reflection maps and vantage Live Link

(1/1)

Robin:
Hi everyone, I posted something in the chaos Vantage forums about an interesting issue I discovered with reflection maps and live link and they told me to repost here as well:

​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: (and keeping exactly the same dirty/smudgy reflection glossiness map)

* 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.


* These tests are using a fresh scene, which I tried after realising it was happening in other scenes
* I've tried using corona phyiscal material - same issue
* Tested on another machine and same thing happens
* Im using corona 12 hotfix 1, MAX 2024 fully updated, Vantage (latest), Win 11
Thanks for any help, really excited to use live link as I love vantage, just confused why this is happening.
