View Full Version : Weird modelling problem
Instead of a smooth evenly curved surface I get the result shown below.
Strange thing is it looks ok in the editor window but something obviously goes wrong when rendering. The geometry around the 'dents' is pretty messy but even when deleted I get the same results.
Any thoughts on what may cause this strange sort of shifting geometry...? Or better yet, what may solve it... :)

can you post a file? i'm not clear what's supposed to be there and what isn't.
I included another picture of the editor window, unfortunatly I don't have my own webspace so I can't put the file up for download.
But the second pic should help clear things up. As you can see from the editor view, those 'second' dents shouldn't even be there and they're also in the wrong place (not in the center). I just want nice smooth dents instead of these dents in a dent...
Never mind the mess below (I'll have to redo that part).

Hm, erm, I dunno this looks to be more of an error you made, To make sharp extrutions in hypernurbs you should better define the area surrounding the extrude. For example, make and inner extrude of 0.01 and then extrude and you will have it sharp.
I know, I got a pretty good grasp of modelling in Cinema.
But I just want to get rid of the weird 2nd dent in each of the dents (wich you can see in the first pic).
Even if those 2nd dents are caused by something I've done they're still in the wrong place. The poly's of the bigger left and right dent are perfectly in the center of the surrounding poly's, but the dents are far from centered...
There is defenatly something wrong, but I'm having trouble explaining it...

did you check your weighting for the dents that are messing up?
Check point weights, poly weights and edge weights.

You can send the file to c4d@sean-paul.com and I will take a look at it if you like.

i dunno. a couple things:
points that have more or fewer than four edges coming into them can sometimes mess with weighting.
could the difference in the appaarent depth be caused by a difference in hypernurbs subdivision levels for editor/renderer?
if vestan can't help you, you can send me the file to the e-mail in my profile, but i probably won't get a chance to look at it now until tomorrow afternoon (EST).

I think that's your phong shading, try setting it to 50% or something....

Could this be an artifact from a light with a soft shadow? I "recreated" a similar problem here...
The pic shows from left to right -
Hypernurbs turned off (Editor),
Hypernurbs turned on (Editor),
Hypernurbs turned on (Renderer).
(sorry, bad compression)
...when I deactivated "absolute bias" of the shadow, the problem was gone.
Maybe that helps?
That fixed it, thanks alot...! :buttrock:
I completely forgot to even check if it had something to do with the lighting because I had them turned off in the 'editor' view... :hmm:
Thanks all...!
