Title: Different result on different Corona version
Post by: LorenzoS on 2018-09-03, 09:36:43

Hi all,
i have this strange results using different Corona versions.
It's a know bug?
The materials are glass and liquid inside with SSS.

Thank you.

We'd need to know more to be able to take a look at what is going on - at best, sharing the scene would be awesome (https://corona-renderer.com/upload), but if that can't be done then at very least some screen grabs of the materials in question :)

The scene actually renders the same in V2 and V3. If you switch to Beauty in the VFB, you will see the same image.
The difference is in the LightMix result. If you reset the LightMix to values of 1 and pure white colors, the two versions will give identical results. But if you lower some intensities, you will see them become different.
I believe this is due to this fix:

• LightMix now properly works with lights having “Occlude other lights” disabled

So it is now the expected result.
