Models

Hello, sry if this is not the correct section, i been looking for many webs, is someone know what is the correct number of polygons or how complex models accept the borfs map editor, i been playing with dragonica models and those models are accepted but only in the editor, when i try to test it in game, the dont see, the tiles are occupied but i cannot see the models... i been trying many models from different games and even different kind of pages, but still cannot find model to work properly.... sry for my bad english.

thx in advance.

Best regards
