Title: Strange gradient in bump
Post by: sprayer on 2016-04-25, 21:23:29

Is this a bug appearing then increasing bump value more than 1.0? Daily build. As bump i am using small cellural map

Looks like you ran into the Shadow terminator bug, you can read details over at the corona helpdesk: https://coronarenderer.freshdesk.com/support/solutions/articles/5000516258

You may also try to give that lower portion a solo smoothing group

This is our no.1 bug that needs squashing. It's a real issue on every single job we do.
