Displacement

Hi there,

I put a translucent displacement material on my crystal-mesh (not meth!) but unfortunately it kind of destroys it at the corners (s. picture).
I already used the "optimise" command on the mesh with no result. Any suggestions?

Thanks alot!

Hi there,

for the sake of not making a new thread i will posting my problem too in this one!

also got some trouble with displacement on corners =/ is this a "normal" behavior of octanes displacement handling or is there a solution for it without patching arround the UV! :cry:

tryed some noise displacement with the example scene - corners always breaks up with "noise"?! =/

This is exactly the same issue, nbeynond.

I´m looking forward to any solution...

I think you don't know how works C4D shaders in plugin. Do you expect it's interpreting in gpu as tileable? No. It converts that to a image.
Always you should keep to feed the gpu by a tileable texture. See my sample for correct usage.

I don´t know what i have to expect - i´m no developer just an artist ;)

THX for the answer and example scene! :)

but still even on the correct displacement material the corner seems broken?!

and so the conclusion is we can´t use regular noise shader to generate displacement?!

i'm both. It depends to what are you doing. I hope that you understand the logic on c4d shader usages. Also it does not work on 90 degree connections i think. Make some bevel there.

still at this state the diplacement seems kinda "hard/tricky" to use... =/ (at least on hard surface)

Maybe! :?
Try changing the value shift.
Example:
Amount 0.010
Shift -0.010 or -0.005
and pyramid try using spherical UV
