Issue with VrayALSurface SSS not reading bumpmap

[MikeAtDIG]

Using the VrayALSurface Material with SSS at 100% shows no effect from bumpmaping/normalmaps when using CPU rendering, but renders fine when using GPU. Only the reflections and diffuse show bump/normals
Using Vray Displacement does however render the normalmap effect on SSS, just not when plugging a map directly into the materials bumpmap slot.
This issue seems to persist on both Vray 3.x and Vray Next Update 3.

Thanks in advance for any help solving this issue.

Hey, Mike,

Thank you for the post. Can you try this setup as a workaround?

Cheers,

I tried it, but this doesn't seem to work. Here are some images to show the differences.
First Image: Default ALSurfaceMtl with bumpmap/normalmap ( no effect )
Second Image: ALSurfaceMtl + BumpMtl (some effect, but not right)
Third Image: Default ALSurfaceMtl +VrayDisplacement (No Tessellation, only the normalmap produced by it)

I'm not at home atm so i can't render a VrayNext GPU version, but the results are consistent with the displacement version, just, without the displacement.

Any word from a dev on this? Perhaps any other workarounds? Or confirmation that it's a bug that is being looked into?
