Anyone knows how to connect a procedural texture (noise for instance) to the bump map of the new principled shader ?
if I use “bump & normals” tab there is only a “texture path” string parameter
and the inputs for bump are all strings except bump scale and filter width

Thank you

I highly recommend you watch this:

Its the brand new masterclass…

Yes I watched it …

Probably it's not possible to do it using the pre-built normal and bump inputs in the principled shader but I guess I have to use material builder node

We very recently added new inputs in the “Other” group, where you also find custom uvs and displacement. Try it with the latest build!

I found that if you plug your procedural bump map into a ‘displace along normal’ node first, you can then plug the output dispN from that into the baseN or CoatN on the principled shader.

Thank you I'll try that
