X Import for wpc_x

edb · (This post was last modified: 04-27-2023, 10:10 PM by edb.)

Hello,

I've added .x import to complement the export part of the wpc_x plugin. I've tested with various .x files and I've added a pull request.

wpc_x.tar

branch name: eb/x-import

I found and tried importing some x file models by googling.
It was difficult to find x file data...
The sites introduced below are programming tech blog so,sample models are simple.
In each site,there is a screenshot about the 3D model for itself.

Also,I installed Blender-XFileImporter for what kind model inside in the files.
Some sample files(Contain Animation,skinning,terrain) could not import even by Blender.
So you don't have to deal with everything. Smile

------------------------------------------------
Import failed
dosei.x in XMesh.cab
It is a charactor model with 3 material colors using.(9668polygons)
https://asura.iaigiri.com/OpenGL/gl44.html
https://asura.iaigiri.com/OpenGL/Downloa.../XMesh.cab
Import the file but nothing action.

Import failed
Box.x it can download from Box.x XFile from a tutorial site.
https://yttm-work.jp/gmpg/gmpg_0022.html
It simple data just a cube only. But Import failed both of Wings3D and Blender.
Nothing happen(It has no UV data)

Nothing happen
It simple data just a cube,all faces are textured(bomb.png) (12polygons)

It is a simple car model that has 3 colored materials.(44polygons)
Author said the file it made by LightWave6.5 with DirectX Exporter plug-in.

Thanks tkbd, I'll be looking into those .x files soon.
I might also implement binary support.

I've made a bunch of fixes after trying the different files,

The newest beam build of x_import.beam:
wpc_x_import_1.tar

edb · 09-04-2023, 10:56 PM

Hello,

While doing tests with the importer a few months ago I've noticed the exporter wasn't making the models "left handed".

I've found some time to make a change to DirectX export to add handedness and the models can be exported "left handed", with "right handed" being the same as before.
wpc_x.tar

My github branch for this change is:
eb/x-export-handedness
