[AnneKitsune]

The png images found here https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/Cube/glTF cannot be loaded by the engine currently.

I'd like to take a look at this.

Do you have a gist with how you were loading the scene?

There is a lot of unrelated things in there. I suggest modifying the gltf example of amethyst.

@Valinora Are you current look this?

[Valinora]

@marciusvinicius I've been too busy, sorry

[marciusvinicius]

@Valinora I will try take a look, I'm a newbie here and I want something simple to start. thanks

@marciusvinicius great, feel free to pop on discord if you need some help.

[AnneKitsune]

So an easy way to start would be to

• Clone amethyst
• Replace add this file in examples/assets/forgotthename https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/Cube/glTF
• Change the gltf example to point to that file.
• Change the gltf example to not use joints (main function->renderbundle->remove with_joint if its there)

Thanks @jojolepro I'm starting this today. hope I can fix it :D thanks for all supported

Hey @jojolepro, Following your tips and using the 'gltf cube' I get the right result. How you can see above

Maybe I'm using something different from you, I'm on master and using the GLTF example to run this.

The only thing I note, is the texture don't look right, how you can see on this exemple redering on three.js They have some "stone" texture

Image with right texture

But This can be something with light, I can't say.

Not sure why, but the issue fixed itself. Thanks for checking it out :)

[marciusvinicius]

@jojolepro nice, Was nice, look the code, I'm understand better the amethyst now.

My guess is that those pngs are progressive, which we didnt support before, but someone made a PR not that long ago for that.
