Question

help with blender and horizon needed

Who can help me? I would like to transfer items from Sketchfab to Horizon to use in worlds, but I can't do it. I've tried this via Blender (4.3/4.4), but I can't get any further than downloading an item in GLBT or something and then ending up on a Blender screen. I've already tried several ways, but every time I try to import it into my item list, Horizon doesn't accept it. I've already watched videos, but I can't figure this out either. It's not explained clearly enough for me, and my English isn't that great. I can convert structures to PNG for my worlds, that's no problem, but it's purely about 3D items like houses and objects.

I believe file type must be FBX

To import a model, it needs to be an FBX file. You can read this getting started with 3D model import  documentation to see the basics of how to import an fbx file into the editor.

You can also follow along with this First 3D model import challenge to see how the import process works.

    I've already tried the fbx file, but Horizon won't accept it. I also don't understand how to save something on Blender. I've read pretty much everything I can find, but I just can't figure it out. YouTube is also a problem.
    That's why I'm asking for help.

    I'm sorry the import process is not going smoothly for you. Can you share what error the desktop editor is showing you when trying to import your model?

    As I mentioned in my previous reply, I would highly recommend following along with this tutorial and its included FBX file as a first step.

    In Blender use the 'Export' option under 'File' and choose FBX. Make sure 'Selected Objects' is ticked.

    If you have materials, which I am sure you do, make sure to follow the correct process, as this bit can be a bit confusing - https://developers.meta.com/horizon-worlds/learn/documentation/custom-model-import/creating-custom-models-for-horizon-worlds/materials-guidance-and-reference-for-custom-models

    As a basic test, with the default cube in Blender, create a material called 'Base' and make sure it is 'applied' to the mesh. Go to Texture Paint > Image > New and then save the Image as 'Base_BR.png'. The _BR part is important and can cause errors if incorrect, which I suspect is what is causing your import issues, so make sure you read the link above so it can tell you all the tricks. 

    Finally, export the default cube in Blender as 'Default_Cube.fbx' and make sure both files are in the same place so you can select them together.

    When you import into MHW, shift select 'Default_Cube.fbx' and 'Base_BR.png'. You should then have your 3D model and texture in MHW. 

    If all this works then it should give you an understanding of the export / import process and we can then look into your more complex workflow using SketchFab.
