Hello,
I have a glass material of which i changed the opacity to a very low number, but it doesn’t affect the glass in the editor at all. What could be the problem?
It now looks like a mirror, but i’d like it to look like a regular glass window.
Kind regards,
Philip
Also, somehow the trees i used (european hornbeam from the epic games store) look horrible when i use the path tracer. when i use real-time rendering (lumen), they look good. what could be the problem?
What’s in the material?
Meh… not really 
You seem to be doing all sorts of crafty things, that are just out of shot.
If you try M_Glass and it looks ok, then it’s something you’re doing 
M_glass is also as reflective as the rest of the glass materials…
is it like a setting in the post process volume?
I’m wondering if you’ve put a HDR in the skylight?
If you’re worried it’s PP, just remove the volume for now.
I have no idea what it is, at the moment…
well, the thing is that it’s also not the post process volume. i deleted it and nothing changed.
This project was imported from a user who built in on a MacOS without any raytracing functions. could it be related to this?
And 2. do you have any idea how to fix the tree issue that i described above?
Thank you very much.
Philip
Tree problem, turn off Nanite
Still not sure about the other…
Hi there! I don’t know if you solved this issue but on the foliage, you can use these commands to sort it:
r.RayTracing.Nanite.Mode 1
r.RayTracing.Geometry.InstancedStaticMeshes.Culling 0
Regarding the glass, you can check the way I do the glass in this post:
Basically I set refraction like
Opacity:
Whole Material:
Material Instance:

I hope it helps!
