Hey @Jesse_Conti!
Could you possibly give us more information than this? We can’t even really be sure what you know to start with. I can say the squares is likely a particle effect issue. Other than that… you’re going to have to give us substantially more detail 
I’m not quite sure what else I can say, other than it only happens when the cars collide and only seen after being rendered out through the MRQ. The glitches are more apparent when the cine cam is close to the objects, but even at a distance there are still artifacts.
It’s a scene I’ve created using the City Sample environment, so the cars that are being hit are part of a mass blueprint and they’re automated within the level.
I animated my meshes to do specific things, and when they collide with the environments cars, that happens…
I’ve tried all kinds of Cvars and changing up the different methods of AA, TSR, etc and nothing seems to help.
Thanks for responding! Any help would be much appreciated. If you need more detail please ask what you’d need specifically. Thanks again!
I myself have not done an extreme amount of particle work, but my best guess is that particle cards are affecting the Post-process. You can try disabling (just click the eyeball) your post process filter on your scene and see how that affects it.
That said, I know that if someone happens along that could help they’re going to ask for video! Do you think you could get us some clips of that happening?
Hope to hear back soon!
I’ve tried everything that I can think of and nothing is working. Its probably something within in the collision settings of the blueprint, I just don’t know what… Again, any help is much appreciated!
If you disable lens flares what does it look like? Is it emitting something super bright?
Yeah, I’ve tried that. The pixel glitches are still in the render, unfortunately…
Thank you for your input, though! I’m all ears if you, or anyone has any other recommendations.
But, to answer your question about a bright light being emitted, yes, there are when the collisions happen. Like a Matrix type of glitch of electrical charges or something…
