Greetings, fellow Jedi! May the Force be with you all!
I'm quite sure some may have known of this, but is certain the majority wasn't.
There are two [more] "unused" bump-map texture inside the game files; for Dantooine's Jedi Enclave in particular- and they gave significant end-result which I believe is nice to have them activated.
So, with vanilla models, the floor tagged as LDA_flr11 and LDA_flr12- as their native resolution is 256x256. Inside the game files there are several higher resolution for these two variant; I take the LDA_flr01 and LDA_flr02 for the replacement. They are sized at 512x512, and had alpha channel on the texture. For whom of you understand on using the KotOR Tool, I believe you will find it easy on assigning each envmap to the respective texture [there are example of TXI's setup by double-clicking certain texture]. One thing that is important is to assign bumpmaptexture for them respectively with the appropriate bump-map [LDA_flr01B for 11 variant, and LDA_flr02B for 12].
I'll get to the point which is the result of the attempt:
It looked even more amazing in-game. By my perspective, is one of the [if not the] most beautiful scenery in the game
This area is tricky. As seen by the floor that the reflection is indeed the outside of the Enclave [CM_jedcom]. I think it should be either CM_Dantne, CM_danint, or CM_dantii perhaps? Which by their looks more resemblance of what's inside the Enclave. But each of the area model share the same textures so, more laborious tinkering [using custom meshes models] will need to be done then
Hope this findings could enhances your K1 experience!
