Hey all,

Been a while since I've posted here. I'm curious if anyone has had an issue with the new Physical Renderer in v13 of Cinema 4D.

Here are a couple comparison frames:

STANDARD render:

PHYSICAL render:

I'm using the basic settings + the indirect illumination for the phys. renderer:

You'll notice the following issues:
1) The cap on the sweeps NURBS is offset
2) The material on the globe is incomplete and jagged

I thought it might be an problem that I'm running my apps off an SSD drive (an OWC Mercury Extreme Pro). I tried it on the built in hard drive and got the same result.

Anyone else have a similar issue or advice on how to better work with the physical renderer?

Do you get the same results when you expand the shape and make it editable? I have not come across any of these issues.

Well, what else is in the scene? To me it looks like your phong is whacking out and in turn seems to do weird things to the rendering evaluation...

Hey guys,

Here's the scene file:

taking too long to render, but for me look very similar so far.

Im on Windows7, no SSD, just regular ol platter drive.

Well that's strange. Anyone know why this would be happening? I just installed v13 a couple weeks ago...

Very odd, but I'm on a Mac OSX 10.6 NVIDIA GeForce 8800 GT and it's rendering fine with these settings:
Sample: Adaptive
Sampler Subdivision: 2
Shading Sub Min: 2
Shading Sub Max: 2
Error Threshold: 20%

So I tried the same file with the same settings on 2 other mac pros, and my laptop.

alt Mac Pro render 1:

alt Mac Pro render 2:

laptop (just a small area, but you can see the same problem happening):

So that's 4 systems I've rendered on here with inconsistent errors...

I'm wondering if this could be some type of conflict with a plugin, script, or something else?

Any Maxon folks on this board?

Well you may be correct - I just restarted, tried rendering one frame and it's rendering without error.

...and I take that back.

Put the settings on high:

I'm getting the same crappy result:
http://dl.dropbox.co.../c4d/phys-4.JPG

The same issues with caps on the Sweeps NURBS and the awful banding and lack of texture - still happening.

[vozzz]

just rendering a scene with those settings you posted, and so far seems fine. only got 4 blocks, but the texture is there, no phong breaking.

[daveglanz]

OH WELL.

This is one of the more spectacularly odd scene files I've ever seen.
I can't still actually figure it out yet. The physical render should have no effect on the geometry of the object... especially when there's no displacement involved. I've received the same errors and in multiple renders, with multiple settings. I haven't given up quite yet on narrowing down the problem.

*BTW... fuck Nick Campbell and his render hungry lights.

@the_Monkey, are you on a mac?

[daveglanz]

Thanks for looking Mike

[jayfaker]

I don't have R13, but stupid question: Have you tried copying everything into a new scene file yet? The only thing I can think of is that the scene file itself is screwed up, which may be why everyone is getting the same errors. I've had to do this plenty of times before.

i opened his scene file though and it works fine...

[eyedesyn]

Was working with a scene file just yesterday that added bright hot spots on geometry with no lights in the scene, no Luminance on materials or glow, nothing, and there were what appeared to be light spots/glows/photons showing up on a piece of geometry using GI QMC+IR. If I deleted the object (which was essentially a cube) the light went away. Very odd.
