Lightmass Spots

HAWK12HT

Hi all can someone please tell me what is going on here oO. I have Oct UDK 2011.

As you can see lightmap textel density is even.

Proper Lighmapped UVs, no fancy options enabled in UDK. Default AO off.

Light build on Production on this test scene and random dots appear on floor and on other areas.

Furthermore to avoid specular seams and seams in general I have chamfer the edges.

All meshes have 1 Smooth group, the reason i have enough chamfering going on to give a fake feel of highpoly in just under 600 polys. .

Uploading the lightmap uv sheet and mentioning the lightmap resolution you are using in udk can help better troubleshoot the issue,for instance if the clusters are too close to each other and your LM res is too small those artifacts can and will occur,also i wouldn't put everything in 1 smoothing group,that can also result in artifacts later on,try to have a smoothing group for each uv cluster and also based on surface angle(e.g every 45 degree)...
