I’m not aware of any paint brushes colliding with lighting as I’ve not encountered said problem until today while I was working and wanted to paint a mud road, until then my terrain paint brush would suddenly disappear near light or objects, I’m not quite sure if it’s a studio issue, or if it’s one of my settings. Appended below is a Gyazo gif of the issue I’m facing.
As seen above, whenever I hover near lit areas or solid models, the brush would disappear. If anyone could provide with an answer, it would be most appreciated, thanks.
This might have something to do with unions or invisible walls.
Do you have any unions where their hitboxes are within the area you’re looking to paint?
Are there any invisible parts (game boundaries, lighting/particle bricks, etc.) that are over the area you want to paint?
You’ve most likely already tried this, but if you go incredibly low to the ground can you then paint on the mud?
(If this doesn’t work then I don’t know how to fix it. Sorry.)
