System Information
Operating system: Fedora 31
Graphics card: Intel

Blender Version
Broken: (example: 2.80, edbf15d3c0, master, 2018-11-28, as found on the splash screen): 2.82 beta

Short description of error

Combine XYZ node binded to vector input seems to give bad value.

Exact steps for others to reproduce the error

Create a shader with only a wave texture, texture cooridinate and mapping.
add a Value node + a combine XYZ, bind the value on Z
Set Z rotation on mapping to -45 => strides are now horizontal
bind the combine XYZ on rotation mapping and set value to "-45" => strides are obliques

See capture

Regards

The value input should be Radians not degrees. The mapping node has a hint so that the UI uses and shows degrees. There is also now a Degree to Radian conversion function in the maths node which you can use instead of the Value node.

It seems that rotation input wants radians, while the mapping value is set in degrees. That's finally not a bug but a display confusion. Maybe change documentation ?

Oh, we found the solution at the same time :)

That's what I realized after writing my report. Sorry for that.

Thx for finding the solution yourself!

Will close as resolved then... [hint is not super obvious, but it is not a bug in the end...]
