Stone Ore
Modified file: \_(Model)\Resourses\Ore-lambert2.(Material).xdb
It was too bright, so I changed the lighting to:
L_NORMAL
Crystals
Modified file: \_(Model)\Resourses\Crystal-ruby.(Texture).dds
They were too bright and pale. I simply made the texture much darker and a little more saturated. Now they are like the originals, but with an improved texture.
Gems
Modified file: \_(Model)\Resourses\Gems-lambert2.(Material).xdb
They are very dark on maps with evening or night lighting. I changed the lighting to:
L_SELFILLUM
Chests
Modified file: \_(Model)\TESTS\dev\chest.(Model).xdb
The gold texture was too bright, and the glow was clearly unnecessary. I removed the glow:
L_NORMAL
Now the model is slightly higher above the ground, which causes a shadow to be drawn along the edge of the gold. It needs to be lowered (4E9A1489-3FAB-4CE2-A07C-011B96F9778E) slightly below the ground. For now, I simply removed the shadows:
false
Grass
However, it still doesn't look very good on the battlefields, so I reverted to the original. But at least its glow can be fixed.

It stands out too much on evening and night maps. I removed the glow:
L_NORMAL
Next, a controversial point, some may disagree.
Reverted to the original water
I'm not sure that transparent water is a good idea. Crooked texture seams are often masked by the water, and in large bodies of water, the ground is often textured haphazardly, most often simply uniformly. And in the Dungeon, transparent water is simply not visible.

P.S. I won't list my preferences for ground textures and some objects, but I also changed a lot there...
To top it off, here's another replacement for the underground gates:

I also modified this mod - I removed all the purple tint, but the link is to the original.
