I’m getting this peculiar issue I’ve never experienced before. My model is treating all adjacent objects as if they have a round edges bump, or something, adding a highlight from direct light on edges. Any idea what’s causing this issue? I’m using 1.7 HF 3 and Max 2016. The scene is lit mostly with a Corona Sky from a large skylight above.
See attached for the problem.
Could be light leaking? Are the walls, floor and celing a single sided polygon? Give them some thickness, so that there are back facing polygons. Essentailly enclose it in a box, making sure to cut out the holes for the windows.
Very strange. I didn’t think it was light leaking, as the floor is just a plane and objects sitting on it were getting that highlight. But when adding a shell is fixes the issue. Thanks!
Yes, don’t intersect objects with something that has zero thickness 
Walls, floors etc should have some thickness to them.
I have somehow never managed to do this in my time as a visualizer. Funny how something so simple can be overlooked (by me). face palm
OFF-TOPIC: apjasko, you may want to check the backgrounds perspective - it’s totally off.
lol I know it’s confusing to know what we’re looking at, but that is supposed to be a huge media screen that shows a live camera of Dubai. I just started on this view today and as of now, that’s just a place holder until I have more information in the scene. Simple corona mat with self illumination and reflection.
Actually, creating a convincing media mesh type screen is something I have struggled with for a while. Maybe I’ll start a thread similar to the wool carpet one where I can get some input and generate ideas of how to create such a thing.
So it was just another instance of https://coronarenderer.freshdesk.com/support/solutions/articles/5000516209
