Matcaps don't work

They are straight up ignored when not checking "Use complete materials", and just use Normal Texture coordinates with TexCoordMatrix1 when it is.

matcaps? As in, Blender's matcap lighting? or something from the bmd files ? I have to admit, it's been a while since I looked into what the materials contained, precisely.

Some meshes (eg. bombhei.bdl from SMG/SMG2) use matcaps as part of their texturing, and the matcap texcoords are not implemented correctly, as they don't even use the camera information

…you mean normal vectors / normal maps? the thing that's used to know how which way a surface is pointing at?

[edbefee3-3888-462a-9411-741b7e9eb54e]

i mean view vectors, matcaps are basically a bunch of math using the mesh's normal vector and the view vector

I'll work on rewriting the material pipeline to incorparate this (and many more changes)

er… OK, thank you! one thing to keep in mind is that, when the "complete materials" checkbox isn't checked, you should be able to export the model as an fbx file, then re-import it, and have the materials still work. …something that I admittedly didn't check since I ported the code for blender 2.8x.

It's possible to make it extremely close to ingame (if not identical)

note how the reflection on the glasses, fingernails, wand and star are

er… you should probably ask blender to show you what it looks like when rendered with Cycles, because there are small things that are rendered incorrectly otherwise. Like, I know it's the case with some transparency things, but I'm not sure where else it could pop up

[edbefee3-3888-462a-9411-741b7e9eb54e]

that's in blender, and it doesn't use eevee-only stuff

[edbefee3-3888-462a-9411-741b7e9eb54e]

it does indeed render quite well in cycles
