I really like the models in this tileset, they are great!
Something is wrong with latest release:
in the xml I see:
<surface partsize="256">
<texture path="textures/surface3a.bmp" prob="0.5"/>
<texture path="textures/surface3b.bmp" prob="0.5"/>
</surface>
Ground textures can either be given in new syntax giving one big texture which is cutted into into small pieces of given size like this:
<surface partsize="128">
<texture path="textures/way.png"/>
</surface>
Or in old syntax, where you have several tiles, like this:
<surface>
<texture path="textures/surface1a.bmp" prob="0.15"/>
<texture path="textures/surface1b.bmp" prob="0.17"/>
<texture path="textures/surface1c.bmp" prob="0.3"/>
<texture path="textures/surface1d.bmp" prob="0.21"/>
<texture path="textures/surface1e.bmp" prob="0.10"/>
<texture path="textures/surface1f.bmp" prob="0.02"/>
</surface>
Don't mix old and new in one tileset!
I miss good textures for the way and I don't see the colored way texture you showed in your screenshot. Another texture which does not show is the cliff texture.
