How to extract/insert Models from/to allMeshes.g3d (CI)?

[Kratzean]

Download works, but the application doesn't work
Do you have a readme?

Now it works. the problem was, when I add a model, which includes a texture (like the creatures or the waterfall.l3d), thee compiler doesn't work.
I need a way, to separate the textures/models, like the other meshes and link they inside of the g3d file, but how?
