View Full Version : Triangulation breaking large flat surfaces

Hi UDK pros, I'm having a problem I cannot solve.

I modeled this glass door in Maya, using quads, and then auto-triangulated when brought into UDK.

The problem is that it puts 2 tris right on the main face of the glass door, which looks terrible when I apply my glass material to it:

Does anyone have an idea of how to properly model a large square flat surface without this happening?

Do you have auto triangulate with obey hard edges checked in the axmesh options?

I'm not using AXMESH, I'm using Collada exporter with Maya on a Mac. I will check for that option though...

No, it doesn't have that option. But it doesn't seem like that would matter, it would still need to split the face into 2 to obey the "triangulate" rule...

Any other ideas?

Not familiar with Mac and should state that in your original question. Because it appears that the two triangles are broken up... at least in UV, what I would suggest is triangulate it in Maya, make sure UV's and soften edges are all set, and then export.

Unfortunately, that didn't work either, but I think I might have found a very sloppy work-around. BSP can be quad-modeled, therefore has clean solid flat faces. BSP can also be "converted" into Static Meshes once modeled, so I might have to just export the door without the glass from Maya, and then use BSP for the glass in the middle of it.

Messy, but I juuuuuuuuust tried it and it works!

Damn, use the SHOT tags...


But just have those sides come together on the inside...

Just looks like one face the normal is flipped, triangulate in maya before you export it then go into hi-quality rendering and turn on occlusion culling (single sided) this will show you by rotating your model which way the normals are facing.
