Keep Quads import setting doesn't work

Hi,

I've imported multiple character models to my scene and I noticed the meshes were triangulated although the originals have quads. There's a box you can check in the import settings that says 'keep quads' but it doesn't seem to do anything. Meshes are still triangulated. Can anyone help me?

 

Thanks for your reply.

It's not one specific model, but all models. They all have quads. We try to keep our models as low-poly as possible to keep a certain frame rate in our scene, because it has like 800 different characters running around. If every model is triangulated that means more polygons right?

Where and how could I upload a model so only you can check it?

Thanks

 

Thanks for your reply!

So if everything ends up as triangles, why have the option 'keep quads' in the model import settings?

Are you sure this won't effect performance because, as you can see in the screenshots, it doubles the amount of polygons.

I've attached 3 images. 1.Original Model in C4d 2. Imported Model in Unity 3.Import Settings Unity

Hope you can answer my questions.

 

Thanks for clearing this up.

If this triangulating doesn't effect performance too much than I'm ok with it.

Best

 

For what it's worth, there appears to be a breaking change in 2021.1.0f1 in the way Keep Quads is applied.

I've posted about it here: https://forum.unity.com/threads/cal...mic-mesh-cases-the-mesh-to-disappear.1087484/

 

While I understand that everything eventually renders as triangles and ultimately we should not be concerned with the performance when comparing quads to tris, there is still some confusion here. Why does "Keep Quads" seemingly have no visible effect on the imported model? In my tests, a model built entirely from quads in Blender shows nothing but triangles after importing into Unity. Why is this? Is this a bug, user error, or misunderstanding of what "Keep Quads" is actually doing? Clarification of this point would be greatly appreciated. Thanks.

PS - using Unity 2020.3.12f1

 

Necro'ing the thread but it was unanswered.

The reason is looks the same is because to render the mesh and show you it means it has to be split to triangles to be rendered by the GPU, so you're going to see triangles with the wireframe shader regardless. All the "Keep Quads" option does is generate the mesh buffer layouts in a way that the Quads can still be derived from it.
