Awesome discovery.

Thank you very much for sharing!

Hmm.. This doesn't seem to be working for me. I seem to get a lot of artefacts when used on more complex surface. Like a hand for example.
I'm using the mix material as suggested. It looks fine when placed on a simple cube but on more complex geometry it seems to start to get funky.
Any thoughts on a workaround and is this an issue likely to be fixed in the 3.0 update?
Thanks all.

Hmm, for me it works without material Mixer node also. I tried (it's loose node on right bottom) both (with and without mixer node) and it looks exactly same. You even can plug in just one input for material mixer and leave amount at 0 ot 100% (depending which one you plugged) in and it still works, But this way it's one node less, or I'm missing something ?

In your example Lewis, are you certain (sorry to ask stupid question) that the bump is contributing. Does it look different with/without the bump input?

Yes, those small noisy bumps are from noise procedural. If I disconnect bump then i get smooth sides of mountains/rocks.
Check the difference (sorry for watermark I've not activated license here at work machine since i have only GTX 660 so i don't really use it at work anyway so this is on Octane 2.16 demo in this example )

Hhm, Now see that confirms what I thought, that bump and displacement 'do' work. Why are folks saying it doesn't work?

hi Lewis,
what happen if you use a normal map with displacement?

Hmm, good point, I've not tried/tested that but then agian why woud you need displacement and normal map in same time when normal map is just "faking" displacement effect ?

I thought normal was used (sometimes) as better bump. I have models that have displacement and normal (rather than bump). Havent' set them up for octane though
