weird uv / unsupported feature in spirit tracks models in viewer and exported models

[steventylerseanherr]

hello
at least 1 model in spirit tracks seems to use some kind of offset that apicula doesnt seem to support

the line in the grass here should be lined up with the rest of the grass to give it a smooth transition to sand

and here in the desert
it does not do this ingame
dumped model do the same

using what i know in blender i can easily fix this on exported models


but without a material editor of some kind
i dont know what is correct and what isnt without having the game right beside me

Please attach the .nsbmd file and any necessary .nsbtx. Also, are you importing through .dae or .glb?

Thanks. Looks like #25, there is clearly trailing data at the end of the material block for a texture matrix. I've never figured out how those work though, so don't expect a fix to be forthcoming.

Note to self, here's the hexdump:
