KHR_materials_variants extension with sceneform

[Efor18]

Hi, Is this glTF KHR_materials_variants supported by scenform? How can I switch between different textures contained inside the model?

Here is an glTF model sample that contains different variants using this material extension.

Can someone help me or point me in the right direction?

Thanks in advance

Hi,

You can ask if the KHR_materials_variants is currently supported by Filament directly on their GitHub.
If it's the case, it will be handled by Sceneform.

For changing the texture inside Sceneform, have a look to the image-texture sample

Hi @ThomasGorisse,

Thanks for your reply, it looks like is not yet supported by Filament, there is a request for it here

Do you know if there is a way of changing the texture of just a specific part of the model, not for the whole model? I.e: In a model of a car, change just the texture of the wheels.

If your wheels are defined in a separate entity inside your glTF, you can change its texture by calling this:

model.setRenderable(this.model)
        .getMaterial("wheels")
        .setTexture("baseColorMap", texture);
