Black splotches on meshes?

Hi,

Sorry if this has already been asked and answered but I wasn’t sure what to search for. I’ve been getting these weird splotches on my meshes. They’re dumped out of maya and then imported in to UE4(4.17.2).

I have done some basic lightmap UV work but I assume that the mesh editor doesn’t build any lighting. I’m guessing it’s something to do with my import settings when I bring in the mesh but I’m unsure as to which one might cause this. I am importing both normals and tangents( exporting them also, with triangulation ).

Any advice?

Thanks.

Edit:

I’ve noticed this only really seems apparent in the mesh editor. Is it a bug of some kind or is it something I should be concerned about?

I was wrong this is happening in the main editor also.

Does anybody know where I’m going wrong?

Thanks.

Can I see a wireframe view of the model? Also, do you have any sort of ambient occlusion map or embedded material?

The ambient map is just pure white. I haven’t baked it in yet.

Looks like Distance Field Artifacts, do you have that on by any chance?

I am building distance fields for skylight AO and also for my water material. Is there a way of reducing the artifacts? It’s not a large mesh, it’s only 100cm squared and it’s not scaled in any way.

Yep, it’s definitely the distance fields.

Now I know the cause I can start figuring out how to fix it. But if anybody has any suggestions I’d appreciate it.

Thanks guys. :slight_smile:

Try to set distance field resolution to 0, it worked for me
