I''ve done a beautiful ship () with 3DStudio , export it into a 3DS format and finally convert it to X format. But when I want to render it I''ve some big matters: Some objects of my ships are not drawn, some other are drawn but their normals are inverted and finnally with only 18 000 polygons I get 13FPS although I''ve a 2Ghz with ATI RADEON 9500 pro.... Why? The other thing I don''t understand is that in most cases, objects that causes matters are instances (when you mirror or clone an object on 3DStudio and you specify it to behave like an instance)... Thank you for help.

First suggestion is to load the file in mview and see if it renders correctly.

3DS files don''t contain normal information, so a lot of meshes start with some basic data problems when you convert 3DS -> X.

Assuming you''re running 3DS, and not 3DS MAX (where, you can just export to X), you don''t have a lot of conversion options to get from 3DS -> X.

I might assume you''re using conv3ds.exe to convert (are you?) 3DS -> X which has its own issues, but unfortunately I don''t have a better suggestion for a converter. Someone else might.

If you want to use your models in your game then you should create a low-poly version of your model. Your ship for PC should be in total around 1000-2000 max or for XBox can be up to 4500 but not more as you probably want to render some other stuff. If you use some decent culling algo then you can push even more polys.

Some invisible objects in your model must have normals flipped so make sure how you model it.

Try running in full screen mode. That could dramatically increase your fps (at least thats the case for me).
