Support blender 2.8/2.9 #5

Open nguyenbs opened 3 years ago

nguyenbs commented 3 years ago

Please do support for newest versions of Blender

davidejones commented 3 years ago

@nguyenbs I haven't tried the latest versions. Do you have any example of the error or issue with it?

davidejones commented 3 years ago

@nguyenbs I tried using the 2.8 and above and see the issues. I think at this point the code needs to be completely rewritten.

In the meantime i hacked something together so you can do a basic import in the newer version. You can try using the io_alternativa3d_tools.py in the branch davidejones/280-support.

For the longterm I might take a look at rewriting this addon its really just depends on how much freetime i have and how much interest there even is in this addon anymore.

I'm aware this isn't really maintained but on blender 3.6.0 (lol), using the sample a3d files provided with this repo, it creates errors when importing anything. sprite.a3d:

Python: Traceback (most recent call last):

Might see if I can fix these various issues myself perhaps? I don't think I will be needing the a3d format since the a3d engine can import other formats just fine but this seems like an interesting thing to tinker with. I assume that the main issues come from API changes in blender.

@Pyogenics I'm always surprised when someone is using this still! So I had started a larger rewrite of this after the initial comment but didn't get very far because of other work.

I'll see if i can throw together something hacky to make it work in 3.6.0

davidejones commented 1 year ago

Hey @Pyogenics If you want to try out this test branch I made using blender 3.6.1 it may work a little better. https://github.com/davidejones/alternativa3d_tools/tree/davidejones/361-support

Pyogenics commented 1 year ago

Yes, it seemingly worked.
