WIP t6 custom map loading by LJW-Dev · Pull Request #539 · Laupetin/OpenAssetTools

LJW-Dev · 2025-10-11T11:20:27Z

Notes:

Techsets are loaded and dumped with my custom implementation, I think it should use the official techset structure but this isn't super important.
The world asset uses a .fbx file and uses OpenFBX as it's loader
It doesn't use any xmodels apart from the skybox, as I found them too complicated to load from the world asset. Definitely should be implemented somehow though.
You need 6 gsc files for the link to be successful and for the map to load on bo2, but 4 of them are redundant (the _fx and _amb GSC files). This could be changed to make it simpler for users to create their custom maps, but i'm not sure if simplifying it is a good design choice.
Maps require footstep tables, but there's no loading/dumping of them right now. I add empty footstep tables so the map will load, we could change this so users can edit the footstep tables but i don't know how this would be done.

note: techniques should be dumped in seperate files from technique sets, but compiling them all into the techset works as well but is harder to read.

…instead of a stream.

…eam, and added techset loading code

…missing image check to the BSP compiler to reduce the output prints when an image is missing.

Hey there, thank you for the PR, the feature is pretty awesome :)
I've looked through a lot of the code by now, sorry it takes so long, it's a big PR 😅
I probably won't have that much time in the upcoming days, so i'll submit the comments I have currently.

I haven't looked at CustomMapLinker.h yet, though since I do not know that much about the BSPs yet, I probably won't be able to say about that part 😅
So generally my comments are more related to code structure and memory management for example.

Also please forgive that I'm adding a lot of comments, it's just my style of doing code review (I'm adding a comment when I have any special thoughts about some place so it ends up being pretty verbose) and does not mean that necessarly everything needs to be addressed or must be solved in a particular way necessarly.
Also I can address a lot of the stuff as well, you don't have to do everything 😛

Again, thanks for putting the work in :D Looking forward to this feature and how it evolves

Done: - Moved custom map structures to their own objcommon header file - Updated GfxLightGridRow struct - Reverted shader_bin file path - Renamed Project Creator to BSP Creator - Removed model loading from BSP creator - Cleaned up BSP Creator and updated the names of structs WIP: - Update BSP calculation code to be more readable and use unique/shared ptrs

- Converted BSP tree generation to use unique ptrs - Updated the linker to use BSP tree unique ptrs and use the new structure of custom map structs

- Updated names to allign with the BSP naming structure - Updated constants file and assoicated uses

- Updated file structure to use BSP naming scheme - Re-wrote BSP creator to use c++ more efficiently

Right now i'm moving to using GLTF as i found it to not have these issues that FBX has had, hopefully switching over would fix the 1st issue (the branch is updated to use gltf ##now).

I agree a warning would be good when it sees not a world material, but when custom materials become possible i doubt many map makers would use the same wpc/wc/etc naming scheme so a full error would be too much. Maybe there's a way to tell if the material will/won't render apart from their naming scheme?

Feel free to add a pull request to the branch if you want to add changes though.

Added the ability to dump and load technique sets.
