Yeah, the internet says, that it is there since R25. But I guess not that much people are using it :)

[C4D] Bug Reporting / Track Modifier Tag ignored by Corona
« on: 2023-12-23, 10:42:31 »
Hey There!

A colleague of mine just recently discovoered, that the Cienma 4D Track Modifier Tag is completely ignored by corona on rendertime.
Unfortunatly I am on holidays right now, so i can't build a test scene. But what he basically did was keyframing an object (not parametric) to drop down on the "ground" from a certain height and use the track modifier to give it some springy bounciness, when it hits the floor. In the viewport it works as it should, but the bouncing is completely gone when rendering it. So corona basically renders the keyframed animation without the additional movement, caused by the track modifier.

I have to admit, that i never heard of the track modifier tag before, so i couldn't come up with a solution/workaround for this. But maybe you can set up a simple test scene yourself and see if this phenomenon is happening to you too.
If not, i can do this, but not until two weeks ;)

I wish all of you some nice holidays and a happy new year!
Keep up the great work you're all doing!


Hey Tom,

thanks for the help, now that whole thing makes sense :)
I watched the Quick Tip a few weeks ago, but there was no explanation of the two different types of MB afaik.

Really appreciate all the support work you guys are doing. Helped me a lot of times to get projects done and make the customers happy.

Have a nice Weekend!

[C4D] I need help! / Corona Velocity Pass Camera vs. World
« on: 2023-10-12, 09:24:13 »
Hey there,

maybe a stupid question, but can someone tell me whats the difference between the World and the Camera setting in the Velocity pass?
Is it maybe comparable to the "Enable Objects" and "Enable Camera" in the corona motionblur rendersettings?

I'm a bit confused here :)
I used the search function in the forums, but didn't find anything.

Thank you and have a nice day!

Ah cool. Then i got that wrong. Thanks for clarifying ;)
I guess i have to have a little talk with my boss then, who is always happy to spend money :D

Thanks for considering bengamin! :)

@mte: I considered royal render too. Does it support corona? I didn't find anything about that on their website.

I'll give that a +1111 ;)

Only solution right now would be either to change the save location and then manually move/replace the mask/pass sequence or to change the filename so that the rgb/beauty pass doesn't get overwritten and then manually delete the "fake" beauty pass. But then the new sequence still has a different filename, wich means you have to re-import/replace it manually in you editing software of choice ;)

Thanks Evan - but I dont think this works for stacked or alpha'd materials.

Seems like decals are the way to go. I just worry about them being less 'sticky' than the regular way. More prone to be accidetally nudged etc.

Maybe you could put it as a child of the decaled object and to be absolute sure, put a protection tag on it?

Aaaaah....ok then our IT-guy didn't install the latest version, as i expected :D

Thanks for the heads up. then this thread can be closed.

maybe i should add: Whe physical camera size is 0cm, everything works fine ;)

[C4D] Bug Reporting / Physical Camera Size and UHD Cache
« on: 2023-08-17, 11:10:35 »
Hey there,

i might have found a new bug ;)

First of, my specs:
AMD Ryzen Threadripper 3960X,
64GB Ram,
win 10,
Cinema 2023.2.2
Corona 10 Timestamp: Jun 20 2023 12:40:33

So here's whats happening:
When i increase the size of the physical camera in the corona camera Tag (e.g. 0,5cm) and hit render with UHD-Cache on (no matter if still or animation setting) the render is stuck at calculating the cache, black vfb and 100% CPU usage. It's not freezing though, only when i cancel the render, cinema freezes and is only gonna quit via task manager. I let it run for about half an hour, no change. Image resolution doesn't matter.

I attached a simple scene for you to try. Just increase the camera's physical size and hit render.

Thank you all so much for your indefatigable efford, to make corona a great render engine ;)

Have a nice day,


I can confirm, that the manual TR settings inside the rendersettings do have a huge impact on renderspeed. I tried a lot lately and for me a setting of 60s/150mb works quite well. But as tom said, the settings depend a lot on your setup, network connection and so on. We are using teamrender server on our little farm ;) So the update interval can be set pretty high, since there is no live preview. I guess you have to play around with these settings a bit, to find the ones which fits best for your setup.


Hey Dave,

as far as i know, this is not possible. I have this problem too (Brushed metal logoplate with alphamasked logo stacked on top).
So, to answer your quastion in the thread title: I don't think you're stupid. And if you are, i am too ;)

Maybe meanwhile there's a solution for this. But if so, didn't hear of it so far. Did you try to use the corona decal object, maybe it works there?


[C4D] Feature Requests / Standalone Network Renderserver
« on: 2023-07-27, 08:16:44 »
Good Morning!

First of, i have no idea if this is even possible, but what about a Standalone Solution for Corona Network Rendering?

We have a small renderfarm consisting of one Server Machine and two client Machines. The server runs cinema's teamrender server, the clients run cinema's teamrender client software. To be honest, i'm sick and tired of cinema's teamrender solution in this configuration. The server software is just not robust at all. It is very delicate on how fast you start jobs after each other, cancelling and deleting jobs is just a plain nightmare. When you have to restart the server software, all of a sudden, jobs with status finished are in the queue again, even jobs you manually deleted on the servers file system are back after a restart and blocking the queue with status "failed" wich forces you to restart the server again. It's simply not possible to rely on that setup at all.

So my hope is, that you can come up with something robust and relyable, so that i can just drop as many jobs as i want and it renders, without having me to check every 30 minutes if everything runs fine.

Would be interesting to hear your opinion on that ;)

Thank you and have a great day!
