Displacer deformer bug?

I've been posting up a storm haven't I....
I seem to be hitting every bug and limitation there is lately. Lots of fun :(

Anyway, Just came upon this weird bug. Apply cloned spheres with a noise shader in the bump channel renders as expected.

if I add a displacer deformer to the group, the bump channel effect goes away.
Known bug? Anyone else come upon this?

After some fiddling, appears to be related to the render perfect setting of the sphere...

strange bug, Can't wrap my head around the logic of whats going on. It isn't the displacer in fact that is the problem, but that the bump only works with a perfect sphere. Uncheck that option and the bump goes away (deforming a sphere with perfect turned on disables the perfect effect to be able to deform)

Int he noises change it from texture space to UV and you'll get a working result, but it will take a lot of tweaking to get the same look again.

Thanks for checking Kai

Yes--I got it working as needed, but it really threw me for a loop. I set up this sort of "rig" often and don't remember having this problem. Sent off to Maxon--I'll see if anything comes of it...

yea I can't for the life of me see why the bump isn't working when perfect is off

Just following up--this was confirmed as a bug by Maxon.

A perfect sphere does not have any geometry and is, together with the Floor object one of the two procedural objects in cinema4D which does not have any polygons and therefore won't work with any typical polygonal render process(like displacment)

Hi Paul

Displacement works fine as I'm not using typical material displacement but a displacement deformer

Its the bump map that gets affected.

Talked to Maxon texh support and they are aware of this error.

Right, that's why it turns it off form being a perfect sphere, but not being a perfect sphere shouldn't break the bump like it is, that's the issue
