1: Missing Polygons. In XSI the polygons are there, ingame their not.

2: Theres an invisible collision sphere around the middle of the model, Not sure what to do, Ace said if you delete the collision it will be fixed

3: one of the turrets is ment to be underneth the ship, but it appears ontop next to the other one

To try and fix polygons, triangulate the mesh, and if that doesn't work, re-draw them.

triangulating in XSI is retarded, the game does that for you when you export anyway. the polygon is just flipped, open the display options for your 3d view and go into the performance tab and turn on backface culling and that poly wont show anymore because its flipped. also you turret got flipped cause you probably cloned it from the top and just mirrored the transforms to put it on the bottom, you have to FREEZE the transforms on the turret and then FREEZE all objects so that they dont revert to teh way they were. the reason why you have an invisible collision is cause you didnt make a collsion or you did and just arent calling it right in the odf so the game makes a sphere around the model.

okay, And how would you freeze transforms?

on the right panel, transform|freeze all transforms and make sure you freeze the geometry after that since itll add the center modifier in the modeling stack in the explorer.

after that since itll add the center modifier in the modeling stack in the explorer.

Sorry, diddn't quite under stand that

you dont really need to understand it just do as he says , but anyways basically all he saying there is that if you press 8 and open up the explorer window and click on the modeling "stack" youll see a center modifier that correlates to what you did with the freeze polygons. Hope that helps

okay, did all that and now Visual Munge comes up with errors
I have a feeling that those might be my fualt, I remade the turret models and nulls


EDIT: i can't get rid of the errors, I think i'll just make the two turrets without dublicating them :p

I think i know whats happening

When ever i munge after saving a new msh, Pc_modelmunge crashes

it only started doing that when i triangulated the model, is there a way to undo that?

yeah theres a quadrangulate button, and again, triangulation has NOTHING to do with anything thats going on with the model, the exporter triangulates the model for you when you export to .msh, no game engine out there supports anything higher than a tri. all your errors are from not making req files, go over some of the docs on creating a side, i ususally make a new side for each vehicle i make just to test. not a single model of mine has ever had to been triangulated, but i dont understand how so many people have flipped polygons when ive never had that problem.

1: Mini, I know how to make sides, I learnt how to do it in a few minutes
2: I never put it in a side, i only do that when its finished, it saves time just to stick it in your world folder
3: I fixed the problem by putting in the collision model again

PS: thanks for the info/help
