Re: UDk lightmap Artifacts
The blinds are the series of long rectangle in the top right corner. The wall is at the bottom. I've tried 256 512 1024 resolutions with medium to production light bake. In production some blobs are sort of merging and the whole blind and surrounding looks very dark I've tryied to overwrite lightmap res int he actor… -
Re: LIghtmaps giving overlap errors on HIGH res settings, but not on low
Double check to make sure your UVs are uniquely laid out, and that there are no stray UVs. My guess is there is a tiny stray UV somewhere on your mesh. When the mesh has a super low lightmap resolution the stray UV is too small to bake down. On higher resolutions the UV would be visible. Also double check to make sure your… -
Seams in UDK using Mirrored geometry, whilst it is all lightmapped correctly
So I have mirroed an object to make use of the texture I have created, in maya, it looks fine.

lightmaps and god rays. Oh my!
Hi everyone. There are 2 issues I'm having with the september UDK. The first is the red circle. For some reason, all my surfaces look like someone washed them with the same rag they used to rebuild their car engine. I, and my instructors for that matter, are stumped as to what the problem could be. I've tried recreating… -
Lightmap (Patchy/Bleeding)
Hi all! I've started a new project where I'm creating a street scene inside UDK, I've never done an environment before and also never really used Lightmass. So I read up on the layout of the UVs, looking at the 3DMotive Tuts and such but I'm still confused when it comes to the padding of the UVs (1px, 2px, 4px?) and why… -
Stable 3D Software that doesn't crash and cause problems? Cinema4D, Blender, Modo, Or LightWave?
Maya is not stable. Something always goes wrong to where I have to restart computer, delete Maya prefs, etc. Is this common in all 3D software such as 3DS Max, Blender, Modo , or Lightwave? Or is it just a Maya thing? Because I am seriously considering moving to another app after I learn Maya (learning at University). -
Re: Lighting issue in UE4, possibly lightmap issue
Yes, I did some Google search prior to posting here, and I've read that whole thread. I thought I set up my UVs correctly for lightmaps in Modo, but I was wrong. I didn't set up the grid spacing and snapping correctly. Thanks, I've solved it now. I gotta say, this is quite a painful process. Got one question though, for… -
Re: [UE 4] Lightmap black spots
Black spots are caused by light map bleeding. The shadow from one shell bleeding across to the adjacent shell. You should repack with more padding. With lightmap UVs, it doesn't matter if the shells are distorted. What's important is to ensure sufficient padding. Also, whacking your LM res up to 256 isn't the solution(as… -
Question regarding lightmaps/culling for unique buildings
Hi - not sure if this should be in Technical or Unreal forums, so mods sorry if I got it wrong! But I think this applies to technical in general. I have a few mesh huts that I made for a forest village I’m creating. About 5 different huts total. I currently have them each as a single mesh that I’m importing into UE4 (so 5… -
Re: Single Map Directional Lightmap. How to bake?
Well you need light intensity + color + maybe shadow...That's a lot for a single rgba map. The only way to use 1 single map is the way epic did citadel demo : baking a huuuge lightmap that could catch all the normal maps details in it. At the end, the normal maps aren't needed anymore. Bye bye to specularity. from another…
