Issues with exporting.

[stevenjwbrooks]

Unknown data type encountered. <class 'IDPropertyGroup'>
eg: <bpy id prop: owner="MAPdxMeshAdvanced", name="shader", address=0x00000261D05C5F88>

I get this error.

If i import a PDX model and re-export it immediately i have issues.

I would love any help.

Could you give me some more info:

• Assuming you're using Blender, which version?
• What model are you trying this with?
• Can you toggle the Blender console and copy paste? (window > system console)

[stevenjwbrooks]

Let me know if you need anything else.

[stevenjwbrooks]

For some additional info:
I continued testing.
if I import and PDX mesh and make no changes an export works.
If i change even a texture, it doesn't.
If i use a freshly imported PDX material on my mesh it works.

Do my Textures need to be dds files?

[stevenjwbrooks]

Changing my texture to a dds seemed to work. Will follow up soon.

[stevenjwbrooks]

Yeah switching my texture files to dds' caused it to export correctly.

It wasn't clear to me that the textures needed to be DDS, even though the texture moding guides on the wiki talk about DDS.

Maybe a check, or suggestion that the files are in the wrong format would be good?

So the addon doesn't touch or care about textures in any way. But it does care about materials, which is what is throwing that error.

Basically in order to tell the game what shader to use, the Blender material needs a custom property on it

It's very simple, just text which goes through to the game. The material you are exporting doesn't seem to have this and instead has some data that to be honest I'm not sure could have come from my addon.

Failed writing property: shader

In your logs, I can't actually see you import the N-1 Starfighter .mesh file anywhere. So I don't know what source file you have for this, but it's likely broken in some way and not actually designed to work with my tool. Your best bet is just to replace the materials on it with ones made from scratch.

Interesting. I got it all working and implemented in game. I'll take a peek at what your mentioning next time I look at it. But the difference between working and not working for me was dds vs png. I'll try and see if I can figure it out. Or share you screenshots of my workflow.
