Still new to Blender - and this must be a beginners question.

I've made a rough, but usable UV map for my object. The UV checker texture is distributed as expected but my bump is not. Coming from Maya I'm used to bump being distributed as a 2D texture, but it looks like the blender Bump node is using the mesh normals instead. Anyway, I'm been loosing hair over this, can anyone point out what I am doing wrong? (please see image below - I did try to change my bump node to "2D" with no effect)

Thank you in advance!

All the best, Jeppe

By default an Image Texture will use the UV of your object, but a Noise Texture won't.

If you don't plug anything into your Noise Texture, it will be projected onto your object as if you used the Texture Coordinate Generated output, which will take the proportion of your object into account, if it is stretched on Z the noise will be stretched as well:

Instead use the Object output, which will project the texture the same way on all the axis:

And of course if you want to use the UV unwrap, use the UV output, and make sure that you've applied the scale and that the UVs have the correct size.
