Smudging/Ghosting with TSR (AA) with Scene Capture Component Texture/Material

[Nick_Dub_1]

Hello,

I’m having a problem with TSR Anti-Aliasing and a Material using a Texture created from a ‘‘Scene Capture component’’. Basically, when I move my character, all the materials in the scene are OK, except for that one material. See the screenshots (below) of when the character is standing still, and when it isn’t.

Any blur or motion blur setting is turned off. I tried all other Anti-Aliasing methods, and they all cause the same problem. Only with that one material. I’ve seen other posts on this topic, but I don’t have problem with Anti-Aliasing in general. Just with that one material. By the way, the material is set to Decal + Translucent. But even as an opaque default lit material, the problem persists.

Also, If I orient my camera to directly film the scene instead of filming the Texture/Material generated by the ‘‘Scene Capture Component’’, the problem is gone. So I know the issue must be the Texture, or the Material.

What could be the problem?

No motion vectors, so TSR doesn’t know how to reject the historical frames. Enable the setting “has pixel animation” in the material.

I tried that, but unfortunately I can’t. Because this is a decal, the material is set to Blend Mode: Translucent, so ‘‘Has pixel animation’’ cannot be activated. The box is greyed out.

Try using sampling the dbuffer in the vase material instead. Then you can use that checkbox on the underlying opaque material.
Here’s how to sample decals in other materials:

I just watched that video and did what the guy is doing, but it didn’t solve the problem.

I did another test and created a material with the texture of the scene capture component, but I set it to Default lit and Opaque (not a translucent Decal). I was then able to check the ‘‘Has pixel animation’’ box and I applied it directly on the vase as the only material on it. And I still have the same smudging/ghosting problem. However, the smudging is not as bad, but still very visible and annoying

You may need to adjust the cvars for TSR then. You can also try TAA instead. Either have a handful of cvars designed to help deal with motion clarity. There is also the “responsive AA” checkbox for translucent materials, it’s meant to help deal with blur on particles but it may help here.

Setting all the materials to responsive AA did it for me. Although I ended up not using TSR, but FXAA instead.
