Ok, I've been learning on how to port properly weapons using maya and stuff and now I've got some weapons fully animated, working with stats and sounds. However, some of them seem to have little holes on the geometry, like the stg44, wich has a small invisible surface on the part where the gun canon joins the rest of the weapon. I think this is due to maya reducing polygons in the exporting proces, so some surfaces may not align properly.

Any clues? Here's an image of the issue:



(I think I can fixing by modifing geometry in maya, but i want your advice)

I am not sure you can fix this

Well I know for sure Cowman doesn't know how to fix this...
I know how to fix this but it's quite complicated and that easy to explain on here, if you want you can add me on Skype and I'll try talk you through it 

go to the hypershade panel on maya and remove the transparency channel for the material. That should solve the problem.

No that isn't the problem, the problem is with the meshes not the materials...

you have probibly deleted a mesh that was there and didnt realise thats all i can think of
