Resident Evil Mercenaries VS (iOS) - Extracting 3D Models (*.mcms)

[Codwai]

Hello everyone, I would like to ask for help in extracting the 3D models (*.mcms) into any other format. I believe the format is simple, considering the models are low-poly. I’ve also included a *.mcts file, which is the texture file, in case anyone wants to check it out. I would be very grateful if you could help me.

your *.mcms file is written in blocks. I made a test plugin that opens models as a point cloud. fmt_mcms.py

*(faces are not simple, need to look into them in more detail)

by keyword POSX you can find all meshes, step back 8 bytes and you will get the number of vertices. stride 8 bytes, vertices as signed short

there are also many textures

example of some meshes (point cloud):

Hello, thank you for the response. As I don’t have much knowledge in reverse engineering and coding, I’m having trouble understanding how to search for the keyword ‘POSX’ and work with the vertices. If you could guide me more on how to start or suggest any tools, I would greatly appreciate it!

I used the hex viewer HxD, and noesis (python) for quick viewing. You can go to the tutorial topic of this forum to learn more about reverse. Use for example my meshFinder (still in testing), or hex2obj from Shakotay, or ModelResearcher.exe etc.)

The files from the attached "sample files.zip" do not contain the "POSX" characters.

Did you use other files from the game?

(I did not downloaded the game.)

You're right. My mistake. I wrote in the wrong topic.

there was a mistake, I wrote in the wrong topic. I corrected the first message, but my subsequent answers remained relevant
