PBS_ColorSplat Metallic and Specular have an Alpha Clip (cutoff) field but lack the blendmode to take advantage of them #3910

Closed Epimonster closed 1 year ago

Describe the bug?

There's an alpha clip slider on both splatmap shaders but no cutout/alpha blendmodes, putting an albedo texture with an alpha channel does not do anything. At this current moment it serves zero purpose.

N/A

To Reproduce

Spawn out PBS_ColorSplat_Specular or PBS_ColorSplat_Metallic from a material tip.

Add a texture with alpha to the albedotexture fields, or adjust the color fields to have an alpha lower than one.

Modulate the alphaclip field and observe no changes.

Expected behavior

If you did what I described above nothing should happen. The expected behavior is that there should be an enum that would allow you to change blendmode to "Alpha clip" or "Cutout" when in this blendmode alphaclip should change how the material renders depending on its value.
