[PC] Richard Burns Rally .SGS/.SGC models

huckleberrypie · June 22

I know the guys over at the RBR community are at least planning to work on the game's model formats so they can be edited in Blender, but I'd like to know if it's possible to rip them for the time being as I've tried ripping the character models from it using Ninja Ripper but ended up not getting a T-pose.

SGS.7z Cars.7z

huckleberrypie · June 27

Anyone interested?

shak-otay · June 27

Low poly models usually don't raise that big interest but the mesh format shouldn't be a big obstacle, or should it?

edit: didn't know whether triangle strips is the best choice here. Saved with normal triangles, drag&dropped it onto Noesis, F4 for backface culling,

doesn't look much worse, imho. But after reviewing I'd suggest using strips.

Same goes for characters (.SGS files), right? I know @Karpati already reversed the car model formats but not the character stuff iirc.

Dunno. If I had known the cars have already been reversed I'd checked the character SGS instead.

Sorry about that. What I do know is that both share more or less the same structure but .SGS has skeletal model information. I could open some of the more simpler ones in Zmodeler 2 e.g. a can of Red Bull but not the human characters themselves.

Char mesh format looks simple. For the skeleton you could try use Durik's skelfinder, read two posts here.

Index and vertex buffer locations seem straightforward, but finding the stride and count is a little confusing for me.

shak-otay · June 27

"stride" (or FVFsize in hex2obj) is a multiple of 4 for float based formats. Using vertex start address 0x3f94 (type in 3f94 without the 0x) for mechanic-1-4_01.sgs and trying 12 in a first step and pressing the go2 button you'll see "NORM" in each 2nd line in the lower left window. This means the FVFsize is 24 in this case.

The vertexcount is calculated automatically (see lower left window) after pressing the go1 button. Provided you set the correct start address and FI count of the FI block. That's just a matter of experience. Or simply divide sizeOfVertex block by FVFsize. Works in most cases.

Struct of SGS/SGC is pretty much same...

What about a Noesis script?

I am able to figure out where the vertices are and more or less the count but the faces are a clincher to get.

Faces are simple for the mentioned mechanics:

EDIT: There's one problem tho: I don't get any UVs for some reason.

I have made a Noesis script but it's basic. Just simple mesh export. No materials/ no bones/ no skin.

Anyway this is mesh struct. Just basic.

Would you mind sharing the script? Or are you still in the process of improving it?
