Thank you for the reply.
The issue is that I’m using a sun lamp, and the leaves (the ones casting shadows) themselves are high res.
Everything in the image is passed through a low px “filter” and the render becomes pixelated.
Does this make sense?
The options aren’t there for me. Is this evee? If so, it’s most likely a different version of Blender.
Regardless, I think my issue is with the rendering itself, not with how the shadow appears before the render.
Maybe I’m not being clear enough. The shadows themselves are fine. They just don’t pass through the same filter that the rest of the render does. Does that make sense?
