11520x1200 Render for Projection Mapping, distant ground texture looks bad. #UE5


We are working on a cinematic render and I have a issue with the ground in the distance have a repetitive digital looking texture. Looking for any suggestions or settings that might help improve the way this scene is rendering. Additionally we are projecting this on a 320ft by 25ft wall with large 15k projectors. Our screen resolution is 11500x1200. We are getting decent render times but the high resolution at scale leaves a little to be desired. If we scale up the scene it gets a little to high on the width. Any ideas would be appriciated. Ive attached a full res image.

You have to re-code the ground material to avoid repetition

Thanks for the reply here is video of some issues. I don’t think the texture tiles are the issue here unfortunately.

The jittering shadow could be from the sun angle being too coincident with the terrain slope, or from the resolution of the depth/shadow buffer not being deep enough.
See if you can find settings for that, and adjust them. And where you have those kinds of jitters, try to make the terrain not have a slope similar to that of the sunlight.

Are you talking about the shadows becoming too simplistic when you zoom out? ( ignoring the strange filtering shadows and the sudden drop in light ).

You might want to try tweaking your directional light.

Basically, you’re zooming out, which causes the engine to simple everything. But then you’re zooming in, by having such a huge screen. But the engine doesn’t know about that.
