Chaos Corona for 3ds Max => [Max] I need help! => Topic started by: elia__ on 2022-11-11, 22:22:17

Hi everyone,
I am a beginner with corona.
I am trying to apply a bump to a wall material. Bump is plugged into Corona BumpConverter. Seems to work fine when used as normal UVW scaling, but when I turn on Use Real-World Scale both BumpConverter map preview and rendered image become flat color.

Hi,
Regarding preview in material editor, it's a known issue, but it's not specifically related to Corona, it's general 3ds Max issue. As for why your texture doesn't render when real-world mapping is enabled, it's likely because of scaling mismatch - your object's UVs has to be scaled to real-world size too, it's not enough to simply enable RW in material alone.

I just tested this myself, He is correct that it is broken. A map that uses real world scale does not work when plugged into bump converter.
The plane on the right uses real world map size with a map size set to 4m x 4m . the left regular planar mapping set to 4m x 4m.
Would love to see this addressed, and to be honest not sure how I haven't personally noticed this before.

Hi, increasing strength for CoronaBumpConverter should fix the issue with RWS, however I am not sure if this expected so please stay posted until we get some further clarification from the team.
