Corona Renderer for Cinema 4D - general / Normal Map for AE?
« on: Yesterday at 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 need help Cinema 4D / 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.

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 / Corona Flickering Problem

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)

Bug Reporting Cinema 4D / 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:

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.

I'm running Corona on a Mac, OS 10.12.4.

Version: 5.0 daily Aug 30 2019 (core 5 (DailyBuild Aug 30 2019))

I wanted to render an animation and use the Gather Data for Later feature of the Denoiser so we can experiment with the looks. This feature only works if you save an image as a .CXR file which I can do if the Save button is held down in the VFB. I see the option to "Automatic save on render end" setting, but there isn't an option for the format of that save. As far as I know, I would need that .CXR format.

Is this possible in the current state of Corona?

Can anyone enlighten me on the LicensingServerLogin.txt process for Macs? This is for Team Render use and one Mac just won't see my Licensing Server or the text file. I only see instructions for Windows users. I put this file in the app directory, but it doesn't see it. In fact, I've put this file in several places to no avail. I have not run out of render nodes if you're wondering. Thanks for any help on this.

P.S. Not sure if this is a problem or not, but after a while, the Licensing Server window where you type in your login info turns completely blank, as in just a white box where the login fields used to be. Maybe just a screen issue, but thought I'd mention it. Doesn't seem to affect most machines however.

We have two licenses so at least six nodes are available. For some reason, one Mac won't connect to activate the license. Any ideas how I can troubleshoot? Everything is the same version and I have used that Mac recently to render.

Thanks.

As much as I love Corona and the images it can produce, sometimes I feel like I'm still using the Beta, except now I'm paying for it.

On ANY Mac in our studio, the Interactive Render window will eventually crash C4D EVERY time. This happens on a range of Macs from the thin bezel iMacs with i7s, Mac Pro Trashcans™ with E5 chips, to the iMac Pro Xeon W chips. MacOS Sierra to the latest OS. 32 GB RAM up to 128 GB RAM. I mean EVERY time it crashes. I recently used it for a very "long" time without a crash... about 10 minutes. These crashes just make C4D disappear instantly with no spinning beachball and no crash report or recovery scene file. Very frustrating that I can't use a major feature of this software so I can see my lighting in real-time like Max users can, or Octane users, or Redshift users or even Cycles users. I assume V-Ray too.

I can't really upload a scene since every project has this issue and I believe it's all Corona and not the machines or C4D. Cinema is the most stable software I've ever used.

I just tried turning OFF Motion Blur in IR and turning ON Path Tracing, both of which are on be default. The IR was more stable, but did crash after 30 min. just playing with some light settings. I guess I'll try with the non-daily build of v4, but I'm not getting my hopes up.

 So I see the latest v4 build had added "Displacement Layering." We've been having issues getting displacement to work when using a Corona Layered material, or as a stacked material in the object manager. Can someone explain exactly what was added? Is this a node feature?

Bug Reporting Cinema 4D / Crash When IR Is Running
« on: 2019-03-05, 16:46:16 »
This seems to be a consistent problem with the Mac version at least. If I have the IR running, at some point it will crash, but it seems like it's during different actions each time. This time, I was adjusting a deformer's settings when the crash occurred, but it happens all the time when the IR is running. I have a ZIP ready to upload.

Scene and crash reports uploaded.

So here's a short clip of a scene I just rendered. Overall, I'm very happy with the results, even with my limited knowledge of Corona. In this section of the animation, we're seeing a lot of movement in the chrome bars along the sides of the screen. There is no movement at all at this point in the scene. There are a few lights around as you can see in the screen shot. I don't believe is the standard idea of dancing noise, since there are many areas in this shot that are perfect for dancing noise yet there is none. I tried rendering as high as 60 passes with and without denoising. Still they dance. Follow the link below to see the clip. Yes, I did also try the Flicker Free option as well with same results, which seems to confirm to me that is't not really noise, but maybe fireflies. Not sure how to tackle them. I will say in this instance, I can just use a still image when it's not moving, but I'm sure I will need to move the camera at some point. I'm also uploaded the scene for you to examine. Thanks for your help.

In the image below, I will be replacing the blue material with a video or static image in AE on the left image. As you can see, will need to have a shadow pass so I can composite those shadows back over my new screen images. The resulting shadow pass (right image) has me very confused and I can't seem to find anything online more that "here are the multipass options" and how to enable them. I was expecting more of a grayscale version of my scene so I can Multiply it over the RGB image. What am I missing here?

Bug Reporting Cinema 4D / IR Not Stable on Mac
« on: 2019-02-06, 18:28:19 »
I've reported this issue and uploaded file in the past, but the problem persists with version 3 release (Build timestamp: Jan  6 2019 17:30:37, Version: 3.0 (core 3). I know there is a new build, but haven't tried that yet. Judging from the change list, I don't think it would make a difference. The IR will seem to to work as it's supposed to for a while, then just when you get comfortable and just work, boom. Crash. Most of the crashes I experience with Corona is when the IR is running. Doesn't matter how simple the settings are or how large the output is. If it's running and you do normal speed work, it will crash. I'm to the point of turning it off and just hitting the render button so I don't keep getting interrupted.

I can upload another file later if you want, but I need to keep working.

Work in Progress/Tests / Glass Render Test
« on: 2019-02-05, 01:10:48 »
Thought this came out real nice. There is still some noise present even after setting it to many passes (over 20 min to render). Don't remember how many and I lost the file. Still looks amazing though.
