maya ramp (U,V wave) issue

[jerre.l]

I would like to control the v-wave attribute of a ramp texture with another ramp texture to create a falloff effect on the amplitude of the v-wave. When I create this network it seems to work fine in the viewport and it renders fine in maya software. But when rendered with vray the result is incorrect. Am I missing something here? Please see the included maya 2018 example file to see the problem.

yeah seems like the noise variable doesnt work at all and the noise frequency doesnt match in vray either. Well not in 3.6 anyway.

It seems that currently, we do not support procedural textures in the V Wave attribute of the Ramp node. This was added to our system and it would be most probably improved in the future. A possible workaround would be to use a file note in the V Wave attribute instead of a Ramp.
