sc 4.5 new chunks

[Frozandero]

This is a PR for making cgf-converter work for SC 4.5. It is a starting point after I experimented a lot during the weekend. It does export the meshes. However I don't think it is release ready for now. I am just creating this PR as a reference point.

FYI I have no idea about animations, if they work or not. My focus was getting the meshes converted.
Additionally wolf and f7c mkii, did export too but couldn't load their materials using the SC blender addon. Very much possible that these changes are not enough to make everything work.

Also seems to not fix the USD exporter yet, I will also work on that but I am not sure if SCBP importer would support it so I can only test it with singular assets.

meshes do export now, however I am still seeing issues with some materials (clipper interior is plain white). Wolf doesn't load its textures at all.

These might be due to the fact that I am not running "export missing" on the sc blender addon but as I mentioned in my reply, this change seems to slow down the logic somewhere.

I tried pressing export missing, on clipper here, it said 241 files need exporting but it was very slow and blender stopped responding by the 7th item and I gave up. I can look into it more during the next weekend possibly.

But I published so that people can check for themselves and improve on it or just use it as inspiration and throw it away completely.

Can you change the target for this PR to release/v2.0 instead of the animation branch? That way I can merge it down to mine and keep the changes separate. And thanks a ton for doing this!

[Frozandero]

I did change it but it still builds on the CAF because I don't think my changes are standalone compared to it I did make some changes to existing chunks in that branch to skip padding bytes in some cases that were causing read errors on the files I was trying to convert. I can look into it more, Saturday.

And again it seems incomplete to me, however I lack the older SC files to test the "changed behaviour" compared to older version to know what is missing. Maybe some stuff were already broken before the 4.5 changes so idk.

[Markemp]

Ok, makes sense. I'll go over it and get some feedback in a bit. 👍🏽

I'm taking a look at this now, but I think I gave you bad advice asking to change the target to release/2.0. You have a lot of the files that I'm working on in feature/caf-animation-support, so it's making the PR a bit difficult to parse. Would it be possible to make the branch straight off of release/2.0 and just include the SC ones you were working on? That way I can merge it down into my animation branch and that should be able to handle all the animations.

This is my fault for letting the caf animation branch fester for so long. I need to finish that up and get it into the release branch, but been struggling with the SC animations. I'll probably make a separate feature branch for that, so that I don't get too far behind on the current work. Sorry for the change in direction.

[Markemp]

Oh wait. I can just merge mine into the release branch and that should make this PR more readable. Let me do that.

[Markemp]

I've merged my animation work into release/v2.0. Can you rebase or merge the latest release/v2.0 into your branch? That should reduce the diff to just your SC 4.5 format changes and make review much easier.

[Frozandero]

Rebase done

Sidenote, I was testing the USD export today to see and found there is some issue related to bones still, probably a trivial fix. Though starfab workflow uses .dae so I only thought of testing it today.

I am planning to check the material id issues that cause some parts to have no materials but that will probably be its own thing (Likely a thing that can be fixed by the new IvoMtlNameVariant chunk but I couldn't find the logic there, which is why I reverted it for now, to not clutter the PR.
