Unity .model

Post by SickAlice » Fri Mar 02, 2018 6:25 am

Sorry if this is been approached before but not being able to find is part of the problem as I'll illustrate. I run into common Unity files as do you of course, .43 being one. I can open that in a variety of programs just fine. The other common are ones with the extension .model. As a common keyword and one that of course is just the generic for 3d types period I can't seem to find squat out about it. Other engines tend to have things like this, TMNT Secret Of The Ooze for example uses the same filename yet I doubt is a related file. Still makes searching and Googling it difficult. Thanks anyone who replies. I will provide an example if needed but figure it's commonplace and anyone has run into it already. Also as a sidenote yet related anyone have any luck with the official Unity engine and game maker/editors? I've had it for over a year now, licensed and still I can import it's filetypes yet do nothing with them much less never even see a preview or something.

Sorry, I had my drive tied up doing something for my mums. Here's a sample, the title character from Hello Kitty Cruisers for Wii U. Unlike the Kart series the driver model seems to be separate from the vehicles which are .43 files instead.

Kewl. So any to go from there to a script? Coding isn't my strong suit and I've never been able to use that program properly despite a year or better of trying to learn. Ty, the intention is to distribute them for modders as well cobble up some mods for Mario Kart.

you'll need a formula to calculate the offset address of the vertex block. I came thus far:
  • size of face indices block at 0x40: 0x4CF8
  • first address after FI block at 0x44 + 0x4CF8 = 0x4D3C
  • DWORD 0x848= 2120, vertex count
  • 0x4D40 +2120x32= 0x4D40 + 0x10900 = 0x15640
then stumbled over the unknown offset (0x15B20 - 0x15640):
unknown offset 0x4E0= 1248
to start address of vertices at 0x15B20

I believe in learning to fish as much as the rest but I went through all this more times than I count and still failed. I'm only on polynomials in school myself to get a picture of my level and more studied and leaned to artistic skills whereas the calculation side has been neglected.
