Forgot to revisit this thread. We think at some point we may have reduced the interval down to 1 sec when we had problems. The funny thing is, when we got it to work, the number was increased back to the original 5 sec.

Thanks for the reply. Yes that makes a lot of sense as far as not overloading the network. No point in sending tiny chunks every second, when you don't need to. Some info on our LAN. Seems to be fast to my little brain.

10 packets transmitted, 10 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.153/0.186/0.220/0.023 ms

10 Gbit/s


The nodes can range from one to eight. Some scenes are too slow on certain nodes. So if we do use all eight nodes, it would make sense to increase the time interval AND the size of the chunks, correct?

Could be also you're using a demo material you downloaded. I've seen that before.

[C4D] I need help! / More Team Render Woes

« on: 2019-10-16, 23:57:27 »

So for some reason, we started getting this strange error when using Team Render. We were rendering a still frame at 4k, with some Depth of Field effect. Previously, we tried an 8k still and could not get it to work at all. Not sure if it has anything to do with Maximum size of packets settings or not, but I've never fully understood those numbers. Although, after we changed to to Interval to 1 and Packet Size to 30, it seems to work better. I just revisited an old thread where TomG talked about large size images and manually setting those numbers to 20s and 256MB.

@TomG Yes, I did upload the scene file. I referenced it in my original post. It was uploaded as part of another thread about crashes, "Crash_SceneFiles.zip" but I figured you can use it here as well.

@Jojorender and @maru We are in full test mode right now and will implement all your suggestions and post back with the results. Thanks for the input.

[C4D] Bug Reporting / Corona Flickering Problem

« on: 2019-10-11, 22:10:08 »

MacOS 10.12.4
Version: 4 hotfix 3 (core 4 (Hotfix 3))
Cinema version: R20.059 CINEMA 4D Studio (single-license)

OK so this has always been a problem with Corona whenever there are very reflective materials. The first time for me was a chrome material. After posting the scene, the devs said my settings for the chome were "crazy." So ever since, we've been using the formula the devs suggested. For reference, I uploaded this scene to the private uploader yesterday concerning crashing issues. Please see the file:  Crash_SceneFiles.zip

Here's the test that's behind this almost black image. This is a single frame of an animation. Rendered twice on the same machine. I stacked them in Photoshop and told the upper layer to use the mode Difference. This will show only the pixels that are different from each frame. In a perfect world this would be solid black as they are the exact same scene, at the exact same time, rendered on the exact same PC. This example is using 30 passes full denoise. WHY are these two frames different? Do the rays being shot into my scene equate to a simulation, where each moment in time could be different each time I render?

I'm also attaching an animated GIF that I hope you can see the flickering well enough. There is a little dancing noise, but it's those bright pixels that appear and disappear randomly and the denoiser doesn't touch them. This animated example was rendered with 100 passes. This reduced some of the flicker, but still way too much for an animation. These cars will slowly rotate so it will be easy to see the flaws.

Also, this Vimeo link show my first render attempt. Maybe only 16 passes, you it really shows the flickering. (can never get Vimeo links to work on these forums for some reason)

Also, when you look at the warehouse and cars scene, I've had problems with those bright reflection "fireflies," but they don't get smoothed out by the denoiser since it's not really noise. We are using the settings for chrome that the devs here recommend.

[C4D] Bug Reporting / C4D Crashing Frequently Lately

« on: 2019-10-09, 22:08:15 »

C4D crashes a lot lately, something I'm not used to dealing with the Cinema. Usually the most stable program I've ever used, and I've used a lot since 1989 (hello Digital Darkroom on floppy disk). Today I was looking at a non-Corona scene with TopCoat material to see how they are built in the reflectance channel. Crash. I then had a Corona scene that's somewhat complex. Also crash. I've uploaded a ZIP file with both scenes and all the crash reports.

When I search the text file, the word Corona is all over it and Tom's name too. I have also removed all other plugins from my system to help avoid these crashes, but obviously that didn't work. I've also tried the latest v5 daily builds with the same results.

Here's some system info:

Any chance you can post your scene file or at least some detailed screen grabs? I'd like to see what your fixture model looks like and to learn how the Volume is set up. I tried with a light fixture model, but I'm not getting good results. Did you use a Corona Light object or a Material?

@Designerman77 Yes, you can use a local network without internet. The process is the same on Windows for the Client. Prefs, Announce to Network, Token. Also make sure you have any 3rd party plugins on each client.

Sometimes I find, in order to see the Windows client on my Mac, I need to Add Machine (in the Render Machines window) and type in the IP of that machine, followed by a colon and the port number. Typically would look like this — 000.000.00.00:5401. That last number is the default port so try that first. If successful, it will then ask for the Security Token for that client. Since you're not running a paid render farm, I'd keep that token super simple to remember.

First of all, your examples look fantastic, but I need a little more detail. "Simply model and be done with it." What does that mean exactly? Did you model light cones and apply a Volume material?

@davetwo That's very curious. I launch my render from my Mac and use a Windows 10-based render client and I have this problem. Wonder why you don't have this problem?

[C4D] I need help! / Looking for Advice for Volumetric Effect

« on: 2019-10-04, 20:27:06 »

This effect with the lights in the background could very well be made in Photoshop, but I was trying to recreate it, at least most of the effect in 3D. The second image is my closest attempt. I cut holes out of a plane, but then added some geometry in each hole to help create more streaks in the light. It's in the right direction, but not quite. I have tried many things such as using a material on a light, having non-lighted discs with a light above to create the cone effect, etc.

I know I can use actual geometry with volume material, that is my next test. Just wondered if anyone had any fresh ideas in the 3D world.

« on: 2019-10-03, 20:44:35 »

I would check the simple things first like if you have a huge texture file when you don't need it. If there is a magazine in the background and the largest it will ever been seen is 50 pixels wide, make sure you don't have a 16k image in that material. Won't render any better, just take longer to sample that huge file down.
