December 21, 2025Dec 21 Hey Reshax fam! 😊 Need some help with a game asset! 🛠️ I got a 3D model from Motorstorm Apocalypse (Evolution Studios) and I'm trying to figure out the format. Suspecting it's .rpk (sample file attached). Anyone clever wanna take a peek? 😅 Game: Motorstorm Apocalypse Developer: Evolution Studios Format: Suspected .rpk Appreciate any help! 🙏 Supercar42.zip
December 29, 2025Dec 29 Supporter Hey, there's a driveclub.bms script from Aluigi which just cuts the rpk into pieces. I'm not clever enough to get better results for supercar42.rpk .

Why did you use the DriveClub script? Are the two games using the same engine? The last picture is definitely something. Crazy UVs from what I am seeing. One last thing, is that Windows 98 I am seeing.

I have no idea - I searched for "rpk" and that was the script I found. Quote One last thing, is that Windows 98 I am seeing. No, the test.obj pictures are from hex2obj.

Also in conclusion… the hex2obj tool didn’t work?

My analysis didn't work (to get correct parameters). It's like not having the correct coins for a gumball machine. Then you won't get your chewing gum.

January 2Jan 2 Author Very very interesting.

January 3Jan 3 Supporter I'm sorry, I've spent much more than the 15 minutes mentioned above. I gave you the parameters so that you can check it yourself.

January 21Jan 21 Supporter Check whether it uses face count (instead of face index count like H2O, which is 3 times face count for standard triangles). Also the padding for vertices is different from FVFsize, the latter is the size of the vertex block while (afair) 'padding' is FVFsize - sizeOfFormat, so padding= FVFsize-12 for floats.

Please check these screenshots out for that thing you mentioned

Can you translate the parameters you gave before into the below format so that i can input in the Modelreseacher. Vertices: Offset Type (float, half-float, etc) Count Format (XYZ, XZY, YXZ, YZX, ZXY, ZYX) Padding Pad Inter Faces: Offset Type (integer, short, byte) Count Format Padding Pad Inter Byte Order: Little Endian Big Endian
January 23Jan 23 Supporter vertices are half-floats and the padding should be 4 (FVFsize-6). Divide faceindex count by 3 to get the face count (roundabout, for tristrips it's a little bit different, usually). But I used automatic face creation with hex2obj, Dunno whether MR has that feature.

Okay lemme try this. Also do you know how to delete topics that I myself created?
January 24Jan 24 Supporter Only moderators can, I think. (I saw users who placed a "can be deleted" in their opener post.)

Alright man, i think at this point you have done welll for me. i willl close this topic. thanks thanks friends you have tried. i will askf or this post to be deleted
January 25Jan 25 Supporter That would delete the work I've done already, too. Very uncool move! Why not wait 'til MRU is ready to process the file in the linked post? MRU= ModelResearcher Ultimate. edit: author of the clone has been banned Edited February 13Feb 13 by shak-otay issue
