Making blend mode translucent glitches with triangles and some meshes disappearing

Hello!
I have created a blender model for a building, and the building has many windows. Whenever I apply a material with the blend mode set to translucent, this is what happens:

There should be 14 windows per row, each translucent rectangles, but most disappear, and some turn into triangles.

What do you think I should do to fix this?

Thanks!

I’d recommend not using translucent materials for a variety of reasons such as this. If you must, you can try changing settings like enabling “sort triangles” on the mesh or “order independent transparency” in the project settings.

But this is why games like Spider Man used shader/material trickery to fake the appearance of translucent glass. I would suggest doing the same, and there is even a built in nodes for it called “interior cubemapping” or something like that.

Thanks for the response. How would you recommend I go about making translucent-like materials? Any specific links or reasources?

Here’s a video you can use. There is a prebuilt node, but I think its worth a watch to know what it’s doing under the hood and why.

Most likely you’re using a Nanite mesh and applying a translucent material to it forces it to display the fallback mesh instead which is much lower quality because Nanite does not support translucency.

Bananable is correct, you should not be doing this with translucent materials, but if you must then you will need to split the translucent geometry into its own mesh and make it non-Nanite.
