Gltfio material samplerExternal

[ThomasGorisse]

Hi,

Can you just confirm that since there are only SAMPLER_2D generated by the gltfio MaterialGenerator even for the

// Transmission Map
{ type : int, name : transmissionIndex },
{ type : float, name : transmissionFactor },
{ type : sampler2d, name : transmissionMap },
{ type : mat3, name : transmissionUvMatrix }

there is no way I can use the default glTF material to apply an external Stream parameter without swiping the whole material to a self made .filamat?

Thanks

Correct, you'll need to rebind your primitive to an alternative material if the built-in glTF material doesn't suit your needs.

If your application is written in C++, one other possibility is subclassing MaterialProvider.

For anyone looking for a sample, here is an implementation using MaterialBuilder in a Sceneform context :
