Looking 4 experienced and not very busy addon maker!
1) Please take a look at this trench model and tell me - why hidden textures don't want to work?
(Test mission and unpbo-ed addon included).
2) Would you be so kind to re-texture this piece of polygons with 2 dummy textures
(to be replaced with 2 island specific textures of earth surface and soil), so it will
be rather good looking on desert and snowy maps.
--EDIT--
Fixed config - thanks to h-
Still need help with retexturing.
