Material fails to compile when virtual texture is connected to opacity mask only through Set/Get Material Attributes

If we connect a virtual texture to the opacity mask output of a material the material will fail to compile. This is expected.

However if the opacity mask uses a regular texture connected via SetMaterialAttributes and GetMaterialAttributes nodes and any virtual texture is connected to other properties in the SetMaterialAttibutes then we still see a compile error.

It seems that the compilation validation logic is checking all texture samples connected to MakeMaterialAttributes instead of just the ones connected through the OpacityMask pin.

In a project where Virtual Textures are enabled, create a material like below.

Note that the texture connected to the BaseColor pin is a virtual texture, but the one connected to the OpacityMask pin is a regular texture.
Observe the material compilation error: "Sampling a virtual texture is currently not supported when connected to the Opacity Mask material attribute."
The expected behavior is for the material to compile.
