Found it. I looked in your texturetilesfloor.2da and found the line for the pocket ships floor - PLC_BC_GRDK03.dds. Then I did a search in my campaign folder; not there. Did a search in one of my saved folders after I had extracted your stuff, and found about 10 copies of it. Once it was in my campaign folder, it worked.
I have PJ's placeables and your tints Kamal, and it seems there's some overlap between the two, or I messed up. So today I have to go through and eliminate duplication between those two folders so your tint stuff doesn't get overridden. Should help shrink my campaign folder a bit too.
Question: I noticed when I unpacked the zip, there are about 10 different locations for the PLC_BC_GRDK03.dds texture; do I need all those copies in sub-folders, or just one? The way I understand it, I only need the one copy somewhere in my campaign folder for this to work. If that's the case I'm going to remove duplicates and shrink my folder a bit.
