I like my scenes/objects to be as clean and performant as possible Still learning UE4 (who isn't), still learning UV unwrapping
I have this pipe modelled in C4D, I think I have a clean UV map When I bring the object into UE4 , the building process takes a good while. Looking at the reasons why this is taking so long I get the results in the white box (see screenshot) ... What are all those unmapped texels ?
I have to admit - I'm getting this result after I cranked the lightmap resolution on the object upto 512 (not sure why I felt the need to do this)
When I'm putting it back to 64, I only get .2% unmapped texels.
Any help greatly appreciated.

Probably you've solved this by now, but if not I've written about unmapped texels (and why they are so important) on my blog http://niberspace.com/blog/speed-up-ue4-lightmap-build-times/
