Imported glb looks "jagged"

Godot Version

4.4.1

Question

Hi,

I’m creating models in Blender, and them importing them into Godot. The model contains pretty much all the elements of my scene (landscape, buildings, etc.). The style in Blender is deliberately low poly, and mostly use flat colors instead of image textures.

The issue I’m having is that the imported assets look “jagged” in Godot (both in the preview and “in game”) in a way that they aren’t in Blender. Some screenshots probably illustrate this best. Here’s it is in Blender:

And here it is in Godot when imported:

For example the track lines in Blender are straight, but in Godot are jagged.

Incidentally, I also use the same models in BabylonJS and I don’t see the same problem there. Here’s a similar(ish) screen capture from BabylonJS:

I’ve tried looking at import settings, but I don’t see anything obvious that could explain this.

Thanks, Tom

Do you think it’s a texturing problem or a geometry problem? It’s hard to tell with static images…

I wonder if some of it is shadowing; Blender’s shadows are probably higher quality.

It feels like a geometry problem, but how would I verify that? And/or let me know what would help you determine whether that is the issue or it’s something else - I could maybe upload a sample asset that I’m seeing this with somewhere?

The easiest way to verify it’s not a texturing problem is to turn the textures off; throw a flat shaded override material on things and see if they still look janky. You could also turn shadows off to see if those were contributing.

Enable MSAA and/or TAA in the project settings

Ok, I’ve done that and it doesn’t seem to change anything, so yeah, seems like it’s a geometry issue rather than textures. So what am I looking for in terms of the geometry side of things?

I’ve done a quick test and this does seem to make a difference. I’ll experiment with these, and read up on them and confirm this is what I’m looking for. Thanks.
