Not Working in ios 12 and xcode 10 about gltfscenekit HOT 5 OPEN

I'm seeing this issue running the Mac version of the sample as well.

from gltfscenekit.

Fixed by making sure all relevant shaders were added to the macOS/iOS projects.

from gltfscenekit.

Are you referring to these?

GLTFShaderModifierSurface_pbrSpecularGlossiness_doubleSidedWorkaround.shader
GLTFShaderModifierSurface_pbrSpecularGlossiness_texture_doubleSidedWorkaround.shader
GLTFShaderModifierSurface_pbrSpecularGlossiness.shader

And:

GLTFShaderModifierSurface.shader
GLTFShaderModifierSurface_alphaModeBlend.shader
GLTFShaderModifierSurface_doubleSidedWorkaround.shader
GLTFShaderModifierFragment_alphaCutoff.shader

Because I changed the target membership on them and it still doesn't work...

It actually works with iOS 12, still no success on macOS Mojave 10.14.12.

from gltfscenekit.

It works on iOS 12. If you are getting nil errors due to shader its because you aren't properly embedding the framework. If you aren't using a dependency manager you may have missed the build flag that is set. Did you make sure to add the build flags?
