Bounding box based UVW on mobile?

Hi Guys,

I have an issue with the BoundingBoxBased UVW function in the material editor.
If I use it to generate gradients procedurally for example, it works fine in normal preview mode:

But If I change to mobile preview rendering level, the Bound location obviously completely breaks, like so:

Any ideas? Is Bounding based UVW’s not supported for mobile materials? And if so, are there any other alternatives for getting interesting patterns procedurally without UV’s?

Thanks in advance!
