Mini Triangle Shadow Artefacts On Character Garment / Mesh

Hi All,

I’m having trouble trying to rid my garment from mini triangle shadow artefacts to no avail. Please refer to the attached.

I made my garment using marvelous designer, converted it to quads (optimised) before exporting as obj to blender, then from blender, merge vertices, add thickness using solidify, etc, before exporting as FBX to UE.

Was wondering was is causing it and if anyone had similar experience and solved it, please share.

Thank you.

Could it be Z-fighting? Perhaps you have multiple meshes superposed on one another; potentially coexisting LODs.

Don’t think that is the case. I’m still at testing phase, so there’s no LODs on the garment.

What about deactivating recompute normals?

Enabling Megalight using Virtual Shadow Map and disabling Distance field Shadow eliminates the shadow artefacts for me. Yay!

Glad to hear you fixed, and thanks for posting your solution.

Welcome, but now I ran into another issue. Distance Field Shadow does not work with Metahuman groom. It makes the hair thin resulting in the scalp visible. And hair card generator plugin does not seems to be working on MacOS.
