How to rip models from Unreal Engine

[Kino-san]

Hey! Thank you for your answer! So yes, the models already submitted contain .png texture files, an .obj, and a .mtl file. At least one also has a .DAE file, I haven't taken a look at that one yet. So I have good reasons to believe the submitters converted those from .psk (which is a format unrelated to sketchup if i understood things correctly) and the associated files into an .obj file. I dug a little into the .mtl file and found the following mention : "3ds Max Wavefront OBJ Exporter v0.97b - ©2007 guruware", so i suppose it's the software they used to convert them (captain obvious, I know). But I have no idea what file(s) went into making the .mtl file, and if i can make a similar conversion with blender.

I don't know if this will help, but the files i extracted from the game contain the following :
- "Animset" folder, containing, i assume, informations about animation. I suppose i can skip those
- "MaterialInstanceconstant" folder, containing .mat and .props.txt files. I don't know what those are
- "SkeletalMesh3" folder, containing .psk and .props.txt files. The .psk is the 3d model
- "Texture2D" folder, containing, you guessed it, the textures under .png form.

And I don't really know which of the .mat and .props.txt files are relevant, and how to mix them into a .mtl file. I didn't check if i can covert the .psk into .obj with blender, but that's an issue for later.

Anyone got any advice for me on this?
