Yeah there are weird quirks between the two. SubUV won’t accept anything going into its UVs input, but it will use Cascade’s linear blend setting, and you can use both SubImage Index and SubUV Movie on meshes. The standard Texture Sample will accept UV inputs for distortion and such, and I’m pretty sure you can use Random on meshes, but Linear (or at least Linear Blend) will break when using it on meshes.
