thx for the link dewing

It is the recommended for beginners because all Sins models were done in Softimage XSI (or which the XSI ModTool is a free version), so the game engine is already built around importing XSI models. If you use another tool like 3d Studio Max or Maya or whatever else, you'd have to important them into XSI and fix them up before important into the game anyway, which is just adding extra work.

There's a tutorial in the Sins forge tools (in the Documentation folder) on how to import XSI models.

its really hard to know how its working

an little help is welcome here

For modeling, i use wings3D ( it is free, simple to use and only 7mb download )... for texturing, i use Gimp ( free ) with a dds plug-in...

But for the final stage, for the hardpoint, XSI is needed... and you need the Stardock modtools too, for convert the XSI file in .mesh file...

For new weapons effect, you need the Stardock particule forge...
