Hello everyone.

So very few people here from XenTax knew me for trying to rip models from Giana Sisters: Twisted Dreams. Well, I have the good news that I eventually figured out the model and skeleton format! I mainly use MeshFinder made by Durik256. It's a bit tricky as I had to do A LOT of fail & retry but the results were worth it.

Long story short, the vertices data are 32 bytes long in half-float; 8 bytes for the position, 8 bytes for the normals and 8 bytes for the two UV maps (UV 1 is the first half and UV 2 is the second half). I still have no idea what the other 8 bytes are. Bone indices and weight are 4 bytes each, each bytes represent a bone which means a vertex can be affected by 4 weight groups. The skeleton is abit tricky for me to explain, so I hope the picture below can explain itself.

With everything in place, the model can be exported with everything it needs. However, I've come to an issue with the tool regarding the bonemap. I always export it to the tool's format (.durik256) and use the Noesis script to convert as the tool doesn't let me use the other export options. but when doing so in Noesis, It always says "weight contains an out of range bone index", even though I double checked multiple times.

I've come to the conclusion I might be doing something wrong with the bonemap. Or it could be the tool that can't understand that FF means 00 in the bone indices, and not data for a non-existing 256th bone.

Here are the files below. The model can be found in giana_cute mesh.bin.nx and hold vertices, weight and face data. It used to be combined with all the models of the game, so I isolated it for convenience. rendershape.bin.nx holds the skeleton data and can be found at the address 1D0D0. I also added the template so you wouldn't have to insert everything on your own.

If any here who is familiar with MeshFinder and can help would be appreciated, altough I highly doubt only Durik himself can help as he made the tool and Noesis script.

I can't see any element buffer info. It must be in another file. I mean element count, index count and offsets.

Well maybe in rendershape.bin.

Element buffer? Honestly, that's the first time I read about it. I have other files that might help, but I'm not sure if that could help as I'm not familiar with the element buffer at all you mentioned.
