Corona Renderer for Cinema 4D - general / Normal Map for AE?
« on: 2019-12-05, 01:38:30 »
What I want to do is render a pass with the normals of a material and use an AE plugin (like Normality) to change the reflections on a surface, i.e. change the reflections from trees to a city street. I can get normal maps out of Corona, but they are yellow to pink instead of the typical purple-to-pin-to-green. Is this possible?

Thanks.

I will confirm that the Xref issue is indeed a Maxon issue. I had this problem last year and learned of this bug over on C4DCafe.com. I didn't realize you had Xrefs in that scene or I would have mentioned it. Xrefs would be very useful if they worked properly, but I don't trust them. I've had a car model's parts explode when trying to scale it.

Doesn't X-Particles utilize elements from Mograph and Instances and Multi-Instances? I'm not sure, but I seem to remember some mention of this in the past. Perhaps when they solve the existing issues with Mograph, it will make it easier to get Corona and X-Particles to play nice together.

@DH3 This sounds like the same issue we had, as well as others in the past. There's a bug with the camera tag and the devs are aware of it. The simple workaround is here in a quote from my previous post:

"As far as I know, the Corona Camera Tag on the Mac is still an issue. If you copy the camera tag setting to the Camera/Post Processing tab in the render settings and check Use Photographic Exposure, everything renders fine. At least it's an easy workaround."

@redstarcg Just saw these shots. Very nice. Can you elaborate on what we're looking at? Just the Expedition is CGI or are the entire scenes? How much retouching was done vs. just Corona? Thanks.

Motion blur has several known bugs they're working on. Curious though, did you test whether it's Enable Camera, Enable Objects or both?

FYI - Knowing more details about your project would help. How large is your render size? Animation? How long?

@Barendby We had a similar issue recently and the issue seemed to be when using several nodes in particular, having the "Client Update Interval" too low (sending data more often), then this seems to overwhelm the network. Go to the Team Render tab in the Corona render settings and change Configuration to Manual. Then you can change those numbers. By default it's 5 seconds and 64 MB. If your frames take a few minutes to render, try 30 sec or more. Otherwise, every node is trying to send 64 MB of data every SECOND back over the network. This can get out of hand quickly.

Let us know if this works. Here's a recent thread I had started on this topic.  https://corona-renderer.com/forum/index.php?board=49.0

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.

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.

Then the clients start dropping off the render job. Didn't matter if we launched the render from the Mac Pro or the iMac. We have a couple of Windows 10 clients too, but only render clients.

Bug Reporting Cinema 4D / Re: Corona Flickering Problem

@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.

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)
