[C4D] General Discussion / Interactive Render Region (View port) on the roadmap

« on: 2018-02-24, 01:51:27 »

Hey devs,

I'm nagging again!

I keep noticing the IRR on the roadmap under the Interactive Rendering card. Just out of curiosity, what would this implementation look like? :)

Cheers!

Hardware / RAM Temperature

« on: 2018-01-31, 09:58:40 »

Hello there,

So I have to admit I usually don't pay attention to RAM temperatures and traditionally it isn't much of a problem in single socketed systems. Long story short, I upgraded RAM on my main workstation today and I noticed how things can get a bit more tricky with dual socketed systems.

Obviously I can only fit 4 ram sticks in there because of the Noctua towers and I thought the two 2696v3s would appreciate being kept cool. Two sticks are at the top of the coolers and two below. The second CPU is hitting ~67 C max.

Anyway, I started thinking about ram temperatures. Afaik most manufacturers suggest temps below 85 degrees C. My hotest stick is hitting 55 while the coldest is 48.

So yeah, just wondering if anyone has any information about it? Its winter time here so I suspect that in the summer I'll see the temps rise to like 60+.

Also, if anyone else is sporting two big Noctuas, did you perhaps manage to somehow cram the sticks below the coolers?

[C4D] Resolved Bugs / Subdivison Surface Editor and Renderer Bug

« on: 2017-11-24, 12:52:29 »

Hey there,

I've got another bug to report. This time is the Subdivison Surface generator.

Corona only takes the "Subdivision Editor" value into the account when rendering. What it should is it should have the Editor value be displayed in the viewport  while the "Subdivision Renderer" value should do render time subdivision.

This is with the latest daily build - 11.10.2017 .

Cheers!

[C4D] Resolved Bugs / IPR & Final render differences

« on: 2017-11-18, 23:42:58 »

Hello,

It seems like I have another bug to report. I hope its not a repost.

There is a difference in the image when working with the final render compared to the IPR. It appears that when geometry is a bit troubled (but still works fine in the viewport / final render) the IPR just looses its cool. :)

Generally what appears to be happening is that some materials just produce odd reflections and they don't respect some of the material parameters like glossiness etc...

It very much looks like a phong issue to me.

Attached is the screenshot and the file has been submitted through the helpdesk.

Again, I hope its not a repost :)

Thanks!

edit: The IPR is on the right, the final frame on the left.

[C4D] Resolved Bugs / Corona AO map - Max Distance

« on: 2017-10-09, 09:55:23 »

Hello :) I think I've found a bug with the latest beta (9.4.2017).

If you set up an AO shader and you play with the Max Distance parameter it works fine. Unfortunately if you slot in a texture map in the "Max Distance texture" slot then the Max Distance parameter doesn't work anymore - it literally has no effect at all.

Contrary, in 3ds Max, you can still use the Max Distance parameter to define the radius of the AO effect but it uses the the "Max Distance texture" as a mask.

The current workaround I am doing is to set the mix mode of the "Max Distance texture" to multiply. That then lets me control the radius as well as the mask for the AO.

Over :)

Gallery / The Art of Pole

« on: 2017-10-04, 14:52:50 »

Hello guys and gals,

I've got a project to share. This one is about the art of pole dancing.

The amount of hard work, discipline and muscle strength required to be good at pole dancing inspired us to create a set of pieces portraying the art of pole outside of the typical public perception.

Pole dancing is not just about strip clubs and heels but can be a form of art and a very creative endeavor.

I (Nejc) was responsible for the scene modeling, lighting and shading aspect while Natalija (www.natalijajagarinec.com) chipped in by doing the posing and clothes. The 3D model is from DAZ.

While we have a ton of critique for this piece ourselves we nevertheless welcome any form of constructive criticism.

[C4D] Resolved Bugs / General speed issues

« on: 2017-09-25, 12:55:54 »

Hey! Another speed issue post :)

Material Editor being slow
https://www.dropbox.com/s/4zf1cbiywl6bcec/Untitled%20Project3.mp4?dl=0

This is a tricky one because it varies. Sometimes material previews take 2 seconds to refresh and C4D lags really bad in between. I've talked to a friend about this and his material editor appeared to be more snappy. It could be anything really but I just figured it might help reporting this. Sometimes it takes 3 seconds just for the preview to refresh if you've changed glossiness from 1 to 0.9 . What really seems off is that most of the editor freezes a lot of the time too - Unfortunately I didn't record that part though.

This does not happen with the Standard / Physical renderers.

I think quite a few people are experiencing this with V-Ray for C4D and the ADVbitmap. If you change any value in there it just takes a looong time to refresh and everything becomes kind of unresponsive.

On my previous PC I don't remember having these problems. Sure, it takes a second to refresh but at least everything else in the material editor was working as it should.

Ray total / Ray Actual generally seems lower in C4D compared to 3ds Max.

I don't have any video links for this one but generally speaking, a shader ball scene in C4D gets me a stat of 4k of actual rays.
A relatively complex interior scenario in 3ds Max can do 10k of actual rays.

In general I feel like 3ds Max is noticeably faster when it comes to clearing noise - I think we are all on the 1.7 daily so I am wondering what could be wrong :) If need be I can prepare two identical scenes to showcase the problem but I don't have a sub for 3ds Max starting tomorrow :)

It really looks like the C4D version is a lot slower for some reason - at least for me.

[C4D] Resolved Bugs / VFB Stuttering

« on: 2017-09-25, 12:54:00 »

Hello everyone, I've got some potential bugs to report! :)

VFB is sometimes painfully slow

https://www.dropbox.com/s/myqi41tknbam5kb/20170925_103005.mp4?dl=0
https://www.dropbox.com/s/0mcirisuiim01x0/Untitled%20Project.mp4?dl=0

As you can see on the two video examples above the VFB stutters. A lot. Its not a "I can't work at all" type of a problem but it is still very annoying as it happens on all sorts of scenes. It also makes spinners hard to use and the render region harder to draw.

What has been done to try and solve it?
- Kudos to the devs for sending me a private version with different thread scheduling (which I think is implemented in the latest dailies too). I tried it but it doesn't appear to help.
- I tried messing with the "Renderer" options under "Preferences" (Custom thread number, Thread Priority etc...) but it does not appear to help.
- I also tried disabling B&G effects but it doesn't help either.
- The VFB interval is set at 2000ms but again, it does not help.
- Tried deleting the C4D preference folder.

Below you can see a comparison video from 3ds Max:
https://www.dropbox.com/s/sph3qz77f8d4z9b/Untitled%20Project2.mp4?dl=0

This issue has been discussed in the past but we haven't really solved it so thats why I am opening another thread. At the time I just thought I better not waste the developers time with what appears to be a problem on my end. Turns out there are quite a few of us having the same issues though.

Oh and I really wanna say how great the devs are, the last time we tried to solve this one we've really engaged on the issue but unfortunately I had other projects to attend to so we haven't really figured out it.

Specs:
Intel Xeon 2696v3 x2, R9 390, 32GB RAM, Windows 8.1

Hope I am making sense here :)

[Max] I need help! / [solved] Shadow catcher shadows on a transparent PNG

« on: 2017-08-10, 14:41:47 »

Hey guys,

This one is a short one. Might be a dumb one too but is there a way to get shadows to show up on a transparent .png image?

Thanks! :)

[C4D] Resolved Bugs / C4D crashes when switching scenes

« on: 2017-07-04, 10:50:44 »

Hey peeps,

Turns out the latest Corona daily (corona-c4d-win-2017-06-27) is unstable for me when switching between scenes.

The crash happens when I render Scene 1, hit stop and then jump into Scene 2 and start rendering that one -> Bam, doom, crash.

Its on a Dual Xeon config with an updated Windows 8.1 .

Hope it helps :)

[C4D] General Discussion / Corona Bitmap tiling

« on: 2017-06-30, 17:44:24 »

Hello,

So maybe I am not doing things right but I do have to ask - is tiling in Corona Bitmap even working?

Anything I input in there just doesn't seem to work.

Am I doing something wrong or is this part not implemented yet?

Thanks!

[C4D] General Discussion / Slowdowns

« on: 2017-06-13, 11:15:47 »

Hey guys,

I have a bit of an issue but its possible its not strictly Corona related - hence the General thread here.

Lately I have been noticing that whenever I render a more complex scene out in Corona (and to an extent it happens in V-Ray as well) the VFB and the whole Cinema gets really choppy. I mean really choppy... Like up to the point where its kinda hard to drag out a render region in the VFB. The VFB refresh rate also plummets.

Oddly, this does not  appear to happen with the standard / physical render.

I also experience slowdowns when messing with material previews sometimes.

The solution that I've found was to limit the amount of threads C4D uses. The problem with that is that I can't appear to limit them to 70 (I have a 72 thread dual Xeon). Pretty much the only value that appears to be working is a value below 36 for some reason. Obviously that halves the performance so it isnt a good solution.

I am posting here to start a debate, maybe I am not the only one that is really bothered by this "problem".

Cheers!

edit: I had this issue on my i7 4790k as well but I suppose it was a little less pronounced.

[C4D] Resolved Bugs / Multi-Pass crashing

« on: 2017-06-01, 13:06:32 »

Hey there,

So I am having this weird crash that happens when I enable multi-pass for the first time in a scene I already previously rendered.

Pretty simple scenario, you render a scene -> stop the render -> enable multi-pass with a bunch of passes (don't think it matters which ones) -> hit render again -> crash & burn.

At first I thought it was just one scene but now I realized its happening pretty much every single time I repeat the process.

What my workaround is is that I enable Multi-Pass -> Save the scene. Render & Crash -> Reopen the scene and then proceed to render again.

Not sure if this was reported before or is a known behavior in general.

Cheers!

edit: Ugh, forgot to list a few things.

Hardware / Biggest Noctua cooler on the Asus Dual socket WS

« on: 2017-02-21, 12:45:27 »

Hello everyone,

I am potentially looking into buying a really good cooling solution for a dual Xeon configuration. Summers get hot so I'd like to go as big as possible.

My question is, what is the largest (and most effective) Noctua cooling solution you can put on a dual Xeon rig on the Z10PE-D16 WS motherboard? Ram clearance is also important so lets say we got 8 out of 16 slots in use...

I'd really appreciate any and all opinions you guys have on this so feel free to chime in. Thanks in advance!

[C4D] Resolved Bugs / Render region, one click bug

« on: 2017-02-18, 17:12:56 »

Howdy,

So there is a bug where if you select region render (in the c4d viewport) and click anywhere in the viewport - this action is going to crash c4d without a save.

Do note, if you click & drag a region render it works perfectly. It is only crashing if you create a 1x1 pixel region render by just clicking anywhere in the viewport once you have region render selected.

:)
