AFAIK in all case you want to precalculate tangent for better normal mapping. This option can be probably removed and forced to always be true

Hello, I was trying to mod my SuperTuxKart v1.2 installation to look like a mix of various old SuperTuxKart versions. When I try to export an old SuperTuxKart v0.7.0 model into an SPM, clicking on File > Export doesn't show it.

I have installed addons in \AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons and enabled them.

I have downloaded stk-media-repo from https://supertuxkart.net/Media_Repo and patched them with original STK installation folder, and I can open built models from the STK installation folder.

But if I opened the same file with Blender 2.79, the rendering will be different.

Blender 2.79 can't install the latest addones, and Blender 4.1 with addons cannot open .spm files even after patching the media repo to the original installation folders.

Should I install specific version of Blender, or use the conversion python script to convert the .spm files in installation folders?

My working environment:
Blender 4.1
SuperTuxKart 1.4

Windows 11 Home 64-bit (10.0, Build 22631)
13th Gen Intel(R) Core(TM) i5-13500H
Driver Version: 31.0.101.5186

Currently using stk-blender with commit 88ff5df.

Currently its very nice to be able to simply click on export and get everything exported into the right place.

Unfortunately when clicking export kart it still opens the file explorer. It should just export it into stk-assets/karts or stk-assets/wip-tracks

Currently when doing quick iteration we need to constantly switch back and forth from Scene data to some other menu we were working on just to export the scene.

Moving it to the top allows to export at any time without disrupting workflow

When exporting the .spm model from blender, the model has no materials in game, it defaults to a white shader. The kart folder has all the textures there.

The materials.xml file is exported with no parameters. I tried to manually set them in the same way as other custom karts but that didn't work.

When I add a main driveline, lapline and checkline I have this message for export.

Thanks

Hi ! I can't import .spm files in blender 2.80. I've copied io_antartica_scene and io_scene_spm in ~/.config/blender/2.80/scripts/addons.
Thanks

We may need something like this:

# .distance property in blender 2.8+ is no longer configurable in GUI, we use the "Radius" now
# which is .shadow_soft_size in API
instancing = []
for object in bpy.context.scene.objects:
    if object.type=="LIGHT" and object["type"].upper() == "LIGHT" and not object.data.name in instancing:
        object.data.energy = object.data.energy / 100.0
        object.data.shadow_soft_size = object.data.distance
        instancing.append(object.data.name)

"Radius" in blender 2.8x is .object.data.shadow_soft_size, so we need to use it instead of .distance

blender expert is it correct?

Hi,
While importing STK files to blender, i get the following issue:

Here's my files:

Due to the deprecation of object proxies in favor of "library overrides" starting in blender 3+, exporting fails with error "Attribute Error: obj has no attribute proxy."

the link "https://docs.blender.org/manual/en/dev/getting_started/installing/configuration/directories.html" is broken

Would you mind uploading a up to date blender exporter for STK to blender extensions when it's launched?
This would be interesting for contributors for STK.

It will be seen by thousands of Blender users!

I believe there is a bug (or at least a bad programming design) in how the Activate field is filled out by its pull-down (for checkline, runline, and lapline objects). The Activate field is meant to be filled out with a checkline group name. The pull-down displays a list of Blender Object names of all checkline objects, along with their checkline group names.

The problem is that clicking an option in this list does not fill out the Activate field with a object's checkline group name, but rather the option's Blender Object name. If the Blender Object name of a checkline object is not the same as its checkline group name, this results in track faliure. In the case of a track with multiple routes, parallel checkline objects (that is, checkline objects that are part of the same group because they are on different routes) must have different Blender Object names than eachother (because Blender objects cannot have the same Blender Object name), and thus only one such parallel checkline object can have the same Blender Object name as its checkline group name.

While this flaw does not ultimately prevent the addon (or even the drop-down) from functioning at all, it does place an unnecessary burden on the user, if they use the drop-down picker, to make sure they always make the Blender Object name of checkline objects to be the same as their checkline groups, and when multiple routes make this impossible, to always pick only the object in a checkline group with the same Blender Object name as its checkline group. A better design would be to have the drop-down fill out the Activate field with, not the object's Blender Object name, but rather the name of the checkline group it is a part of, since this is the data that the Activate field is meant to be filled out with, and not something that may or may not be synonymous with the name of the checkline group.
