When enabling Nanite on my mesh it changes the quality of the mesh to what can only be described as a lower quality.
Here is what it looks like with Nanite disabled:
And this is with Nanite enabled. Notice how the windows is of lower quality:
I found this thread: Huge quality loss with Nanite? and double checked my that I had DirectX 12 enabled.
What else can be the cause of this decrease in quality?
Hi, nanite does not support transluscent materials. So, if your mesh has any transluscent material on it (the window), it will use the fallback mesh which you are seeing right now. The fallback mesh is lower poly compared to the original mesh.
You could split the mesh into two, one without any transluscent materials where you can enable nanite, and one with the transluscent materials without nanite enabled.
Yea, the general thing to do is separate windows (anything tranclucent) from the main mesh, like @chrudimer said.
You probably have a warning in tiny unreadable text in the top left.
An added bonus is it’s then easier to destroy windows as well.
