Even if you clean the canvas manually (ctrl+n)? And what about the flat render, is it red too? If flat render is ok, then you can apply flat material manually.
I am having some curious issues with the Texture:CropAndfill. I was using it fine yesterday and now I am getting different results. I feel like a newb! - I am grabbing the canvas with Texture:GrabDoc. You can see in the second image that the preview looks correct. - I change the material to the Flat Color and then Press…
Yea I cleared the canvas after I used GrabDoc. I tried in Edit Mode and not in Edit Mode. That is the strange thing. If I use the flat material and then GrabDoc... the CropAndFill comes out fine. Like it's pure white. With no color "overlay." But if I GrabDoc with any other material and then CropAndFill it has that red hue.
