Texture node makes image jaggy/aliased

PostThu Jul 15, 2021 10:40 pm

Hi all,

New to Fusion and trying to test a compositing workflow with rendered multipass exr. The main purpose is to be able to render a sequence once and use it for several brands by replacing the texture. The issue I'm having is that the applied texture looks very jaggy, especially on the edges. Including a screenshot as example.

I've also tried a couple different reactor alternatives such as UV positioner and stMap. stMap had a supersampling option which helped a bit but the edges were still jaggy.

Any help on this is appreciated. Thanks!

Have you tried unpremultiplying your uv map with alpha? If uv coords are antialiased, you get wrong values looked up by edge pixels. Unpremult uv-s, do your texture, then premult result with alpha again.
I do stuff.
