question aboutr vraylightmtl

[jodestroy]

i have a question about vraylightmtl.

Is there any trick to add a bump in a vraylightmtl.

Cause we have a ceiling to illustrate and i'd like to add a bump to a map we do that will glow a bit.

any suggestion someone. Should i use another shader?

You might have more success with displacement
