Problem: I’m rendering Freestyle, dark grey toon lines on a transparent background. I’ll composite them on top of other layers, probably in After Effects.
But when I test-render in Blender, it’s hard to see the lines because they’re so dark, and the default background is so dark, too.
I have too many Freestyle line sets to go through them all and change toon line colors to white. Instead, can I change that default background of dark grey checkered squares?
Why it matters? I’m making fine adjustments to objects’ positions, then re-rendering a frame to check if they’re overlapping properly. I need to move an object, see the render, move it again. It would help if I could just see the transparent renders on top of, say, a very light gray checkered background, or pink, or blue.
Can it be done? I can’t find a likely adjustment in User Preferences.
