Hello I am working on a car model in unreal engine and have the windows set up as a material that resembles glass. I am running into an issue because when i run the game at certain angles the glass is no longer translucent. I have attached a video demonstrating my issue any help would be greatly appreciated
Hello there @gwh0014! Let’s try to figure this one out.
From your sample, it seems the crystal is losing its effect either due render distance or angle. Yet, the material, behaves accordingly on its own.
To rule out a possible cause, please try the following:
- Select and open post-processing volume
- Go to In-Details Panel, and locate Rendering Features > Translucent > Type
- Switch to Raster instead of Ray Tracing
If the issue persists, please send screenshots and details of your glass material setup, so we can review all its settings. Additionaly, please make sure to review the current documentation covering transparency in materials, here:
Thank you for your help. I tried switching from ray tracing to Raster but still have the same issue. I have also looked at the documentation you supplied and nothing i tried seemed to address the problem, above is how i have the material set up.
Edit: i also tried zooming in and out, since you mentioned it could be the crystal losing its effect at a distance or angle, and got the same result as in the glass took on the tint you see in the video if i zoom out to far so i guess it is losing its effect at certain angles in front of the car and when zoom out to a certain distance.
Edit(2): I just noticed the glass material for the blinkers is doing the same thing. This seems to be the same issue so i thought i would share a video to show what i mean …
Edit(3): i think i am figuring this out sort of… when i set the LOD to 0 instead of auto the problem disappears but i am now unsure of how to keep the LOD at 0 when the object is in the game.
for the next guy this was the solution go to the asset details panel and change number of LODs to 1
Glad you reached a solution @gwh0014!
To keep the object at LOD 0 in game, please check the following settings in your car:
-
Since its a single asset, you can disable Nanite here:
-
After that, go to LOD settings, and set the following values:
This will ensure your car’s geo is not adjusted with rendering distance, and prevent the glass from losing translucency.
