Reflection artifacts caused by first person weapons

Hey guys,

Was wondering if anyone knew how to get better real-time reflections as I am experiencing a very annoying bug with the reflections on my water surfaces, caused by the equipped weapon of my first person character.

I assumed it was just because I was using SSR’s and that it was to be expected based on that reflection rendering method, but I get the exact same problem when using lumen or ray traced reflections so I’m not sure anymore.

Below is a couple of screenshots for reference. The first with SSR’s and the second with Lumen reflections.

Note the reflection on the waters surface, underneath the head of the axe, it is missing the reflection of the trees hidden behind it.

Like I said, I expect that result while using SSR’s but even when using Lumen I get the exact same result. Am I missing something when it comes to the other reflection methods? I feel like maybe they aren’t working properly.

I have also checked and confirmed that the trees are not being occluded behind the weapon.

Any ideas on how to fix this or on a better method of getting good reflections for my water surfaces would be appreciated.

Cheers

Your mountains are too far away to be drawn into Lumen’s raytracing representation of the scene, so any reflections that are occluded will just reflect the skylight.

You can increase the Lumen Scene View Distance and the Max Trace Distance in your post process volume, but they’ll only go so far.

Hey there

Thanks for the info, some of my mountains are too far away but the mountains right behind don’t seem to be. It’s actually the tree reflections that I’m concerned about. I’ve added a plane with a chrome material to it to better demonstrate what is happening.

Look at the Lumen debug views, they will tell you what you need to know

Additionally… did you even try what I told you?

I did, the mountains are too far away, you’re right. Is there anyway to disable the occluding of the axe static mesh/actor? I was under the impression lumen reflections rendered without care of if they are occluded in the screen space or not.

Other than making the material translucent, which will just create more problems. No.
