Short description of error

when trying to use bump maps - there is no result, both when using the bump shader node and when using normal mapping

Exact steps for others to reproduce the error

create any object, (plane/cube or any other), apply Principled BSDF, add bump node, add amy image of procedural map, connect image RGB to bump height, connect bump normal to principled normal - no result
[Based on the default startup or an attached .blend file (as simple as possible)]

To be sure, this is in the viewport? And you are switching to material preview or rendered mode? (Material 'effects' do not appear in solid mode.)

We require a simple .blend file to reproduce the issue.

Both, material/rendered & f12 all about EEVEE.

I can confirm that, though only when using a custom UV input.
Try this file:


If you connect Texture Corrdinates with UV to the Noise Texture it works, with the UV Map node it doesn't.
