With UV sets set to 4097 it works, thanks!
And the third unknown float indeed seems to control the gloss. Lower values for a more dry effect, higher values for a wet effect. I've found nifs with a value of 667, so I assume the range could be something like 0-1000. Didn't see much of a difference between 200 and 1000 though (in Oblivion it was hard to tell the difference between 20 and 100 as well, so I guess it's the same system only with one digit added). Beth used 20-80 for metal as far as I could see, 200-667 for slightly wet looking stuff like cave/dungeon walls.

EDIT2: Now I'd like to add collision to the mesh. I've seen that Skyrim nifs use a bhkCompressedMeshShape under the Mopp shape. Does regular Mopp collision (with bhkPackedNiTriStripsShape) still work and/or is there a way to export collision as a bhkCompressedMeshShape (in case Fallout used the same)?
EDIT3: When I try to add a regular packed shape to a Skyrim nif it says 'unkown block' and deletes the subshapes. So I guess that doesn't work.
I'll be making stabs at the LightingEffectShader today too, if you come up with anything solid, let me know which name field you've found it in. Right now that block is a mess from my decode, there's a bunch of extra floats at the end that as far as I could tell, were only present based on the first int of the block, it didn't seem quite right. I found a couple of things last night that are very wrong too.
2) CompressedMeshShape is brand-new, it was a major PitA to work out, and it will probably be a while until we understand it better for exports on that block. I've never really 'gotten' collision, but I'd first look and see how it compares to a PackedStripsShape.
3) That's no good, I don't recall any problems there, did you add that block with NifSkope? After my nif.xml updates, corwin made some corrections and ensured that 5 games worth of .nifs would still load properly before releasing his. I've merged that into mine, i'm just in the middle of a pc swap, so I'm not totally up and running yet.
@MadCat221: The exporters start a new shape for each material by design, unless you're talking about something else.
