UVmap named channel not working with RT, bump map

[andybot_cg]

When I render with RT, the named UV channel is not used for the bump map. If I change to manual mapping and use the channel #, then RT works fine. Example file with both UV map options attached. Latest 3.6.03 & Blender 2.79 build (splash screen says 2.78 tho?)

This is still a problem. Has this been looked into? Thanks.

I thought to start a new thread but found this. Its still the same, with Gpu render, mapping settings needs to be Manual to get bump, even mesh is uv-wrapped.
