Thank you.
That’s ok I don’t need the Fab link. I can repro the issue indeed. I’m on it.
Don’t try to edit the model. It’s going to work eventually.
I’ll keep you updated.
Hello, this issue has been fixed.
However there is a catch.
Anisotropy in sketchfab was done in a time where it was not very widely used in the industry and lacked a standard way to describe it.
With Fab, we want to focus on being able to export models to any DCC, and for this we support glTF format.
glTF has an extension for anisotropy that has a specific parametrization and we are now using something compatible in our viewer.
it is described here if you want more information glTF/extensions/2.0/Khronos/KHR_materials_anisotropy/README.md at main · KhronosGroup/glTF · GitHub
In short, we don’t support the “flipXY” flag that was there in sketchfab, and that you used for this model.
When you load your model you will see a warning mentioning this, and you will see that the anisotropy effect is actually rotating with the vinyl.
But, in this model particular case, because the anisotropy texture is centered, it can be fixed with a trick.
You need to go in the anisotropy textures parameters and set the UV scale U value to -1 instead of 1.
here is a video demonstrating the workaround.
Of course, after that you have to save your changes.
I hope it helps
Apologies for jumping in on this thread, but I’ve been trying to migrate my stuff from Sketchfab, and I get a warning saying that my model has an anisotropy flip x y texture and I might need to tweak things. How exactly would I go about doing that? Or do I need to make changes to the texture itself?
