Whats wrong with this picture?

Elodin

Ok it's not the first time I'm seeing this, but in this work, this weird glitch is all over the place. Whats wrong with the shadows? Its production processed and I got weird triangles and squares of black all over.

Does anybody know why?

you have bad lightmap UVs or bad lightmaps. Try rebuilding the lighting and if that doesn't fix it check the lightmap UVs.

It might help if you have a look at the scene in "Lighting Only w Texel Density" mode to check for poor lightmap UVs.

How do I do a proper lightmap?

A proper lightmap covers the whole UV space, no UV islands overlap and there is enough space between islands that are not connected to each other on the actual mesh (no need to leave empty space around the borders) to prevent bleeding.
