Ok so tool is starting to frustrate me. I am trying to build a beta of my RPG map so i can see how things are doing. This is the error when i type in:

tool structure levels\rpg_beta rpg_beta

Couldn't read map file ' ./toolbeta.map'
building intermediate geometry...

EXCEPTION halt in .\intermediate_geometry.c,#444: triangle->material_index>=0 &&
triangle->material_index<old_material_count

I'm assuming i made an error in the bitmaps seeing as the word most used is material but im not sure.

Hmm i probly forgot to add one of the names in there somewhere. Thank you for your help it was much appreciated.
