UMG Render Targets - transparency blend mode takes time to resolve

YT Video showing translucent vs opaque material clarity

Hey folks!
First time posting a thread hope I’m doing it right. I currently have a Widget Component (world space) in my blueprint, I use its render target as a texture in a material. I am noticing that if I’m using one of the transparent modes (additive, modulate, translucent etc) the text takes several seconds to resolve in clarity. However, if I use Opaque as the blend mode, the text shows up crisp and clear.

The best forum post I managed to find is this: UMG Widget Rendering Issue and I’ve tried putting a post process volume around the world space widget to try to disable lumen etc but didn’t get that working.

Also tried the Widget Component in screen space mode. Render target is not valid when I tried that, so I assume in screen space mode its purely for regular UI on screen.

Thanks for any help!

Update, it seems like it may be something to do with the anti-aliasing method - switching from TSA to None/MSAA/FXAA sorts it out but there is now lots of lumen noise XD

It was also suggested that I output the depth and velocity from the material, didn’t seem to have any difference. Will keep looking.
