Is there a way to open the .s3d files?

[Wolfshead Sky]

I've asked this before, but kept getting pointed to programs such as S3dspy and the like, but all that did was help me extract the textures. That would be fine if that was my goal, but it isn't. So before any helpful individual (and the odd snippy one that is no doubt trolling about) decides to point me to something like that, I'll try to nip it in the bud [You must be logged in to view images.

I am NOT after a program that simply lets me extract the BMP textures. I want to open the actual 3D model itself in a program such as Blender.

Is there a way to do this? I've done some digging but haven't found anything useful.

Thanks in advance! [You must be logged in to view images. Log in or Register.]
