nope still not working

in the sketchup the model is clear nothing wrong but when i export in fbx file in 3d max i can't remember how look when i import it but in maya is black model with many edges/lines/triangles,but now with obj file is better maybe the fbx exporting is not working well in sketchup

i think i find solution with obj exporting

why when check to show hidden geometry is not showing nothing ?

any suggestions on fixing the model ?

after checking the triangulate all faces is happen this on maya and 3dmax

playup is plugin for exporting models to cryengine

i check it but is not showing nothing i export with playup even in fbx format but same result

thanks for quick responding but the mats are not the problem the problem is that triangles/edges that sketchup is makes without seen it,how to fix it

why is this happening what wrong im doing to happen this,i use cleanup but doesn't help,please some on help me
