Bumpmap strength not working in Cycles?

[jjn (Jens)]

Hi,

I’ve noticed this since a couple of versions back when my renders suddenly looked really weird on old files. It seem the Bumpmap strength is not working, no matter what I set it too it looks all the same. Doesn’t matter what type of material I use either. Am I doing it wrong?

Bumpmap is borked… try adjusting strength as in the thread below.

Bump textures not rendering at all

Hello McNeel folks, The ability to render textures seems broken. When I add a bump map to a material, the texture shows up in Rendered view, but then dissapears in Raytraced view. This is happening on very different computers, both our classroom Windows 11 pc’s and on my MacBook Pro. [Rendered texture] [Raytraced no texture] Here is my test file. Texture not rendering.3dm (4.8 MB) And here is the System info from my MacBook. I don’t have the SystemInfo from the classroom computers but …

no that does not fix it anymore, that fixed it before it broke entirely.

i reported it months ago it has a tracking number but nobody is on it. i stopped rendering with cycles since then. actually a stop ship issue but nobody cares and noone communicates anything. one of those strangely beghosted bugs. i really don’t get it.

Bumpy Bump?

thanks @nathanletwory, since @andy did not respond and it still is broken i wonder if anyone feels responsible for it? Rhino is unusable to render since then… neither V8 nor Wip 9 work, the bump is so heavy and exaggerated its practically useless now.

Ah okay! That makes sense regarding my latest render in the gallery.

I wondered why the table top just didn’t quite work for me, but I assumed I had to rescale the bump strength. I couldn’t be bothered.

Oh my, that’s really bad. I’ve been such a fanboy for Rhinos/Cycles strong rendering features. Guess I gotta fire up Keyshot again. Please @user_9123125 fix this asap, IMO this is quite a serious bug.

Hej Jens -
