HI! I’m having a technical problem on uv lightmapping.
I try to use lightmap Pack for UDK. but the result looks terrible. Can anyone teach how to set lightmap Pack in Blender?

As far as i know. UDK Lightmapping is different from Blender/Unity lightmapping. You can utilize the same map in Unity. but In UDk, it needs you to manually adjust your light map and keep it stichted, atleast the major chunks. I suggest using your original UV Map and copy it Lightmap as well. Give it a try.
I tried different ways to create UV map for lightmass. If I genereate uv map in UDK, it won’t give me a perfect uv map because the mesh will have few obvious seams and cannot be adjust.
To avoid any seams, in blender uv editor I guess I need to know how to “snap to grid”.
I search on internet, ppl saids go to user preferences–>view & control for snap to grid. Where is it?
Snaps setting can be activated by pressing little “Magnet” icon. you can also press “CTLR” while moving the vertice/edge/face/model to start snapping.
Try to find a tutorial on unwrapping a head model. As i said before , utilize the same unwrap (with different uv slots) for texturing & lightmap.
Upload your blend. I’ll see what i can do.
The “Magnet” icon in uv editor’s only choice are vertex and increment. A new things I’ve found is Shift + S and select “snap selected to pixels”. That does on a grid But no matter I hold Ctrl or Shift + S, it snap on big grid only. When I zoon in to where I can see the smaller unit of grid, it won’t snap to it.
