Hi there,

I was wondering if someone could help me with this issue, I'm just trying to get procedural noise to work as a bump map, without UV's, just using the object's local transform.


Thanks,
Pete

The principled material doesn't have a bump height input. Try computing the bump normal first, and then connect to baseN.

Hey thanks jsmack! That works great.
It's strange but I can't get anything working in that dedicated bump section, it even looks like it has an effect value that should work.


Anyway, your solution is working great so I'll just stick with that.
Thanks!
Pete

The dedicated bump section only works with a provided texture. The effect scale applies to the bump texture. In your screenshot the texture map input has a float connected (from the noise), but it only accepts a string (a file path).

If you are coming from Maya, I can see why it might be confusing. Things are a little more literal in Houdini.
