[C4D] I need help! / Animation Output CXR or EXR

« on: 2024-10-10, 22:34:29 »

What's the setup for outputting multipass exr(crx) animation frames. I tried to use the native save dialogue in cinema but I'm only getting the beauty pass. I don't see any other way to do it; not in the setting or in any of the documentation on line. There's a mention of "editing 100 cxr frames" in batch in the image editor but how to you get those cxr out? I'm used to the VRay which has its own non-native save dialogue, wondering if I'm missing that somewhere in corona?

Edit : picture viewer also doesn't output multipass.

[C4D] I need help! / Re: VRayProxy in Corona

« on: 2024-10-10, 20:05:16 »

I'm coming from VRay for Cinema, and while that implantation was not nearly as complete as the one in Max, it is quite workable. I also assumed that there would be some interoperability between VRay and Corona but it seems like that assumptions was wrong. It looks like Max users have created some scrips(as always) to fill in the gaps for VRay to Corona or the other way around. The lack of even a material converter(the scene converter isn't suitable much of the time) is quite painful - big red "unsupported" everywhere, just as a reminder. It seems like Corona and VRay are much more segregated than I thought despite being part of the same company. Of course now I feel like my VRay assets are useless in Corona so I need to start re-thinking whether this will work.

Regardless, I guess I will continue to use VRayProxy in Corona until it proves unreliable.

[C4D] I need help! / Re: Corona Standalone - lots of issues

When rendering animation I need it for consistency, and to save memory and time not having to start up cinema - you can read about it in the corona documentation. I've been using VRay standalone with vrscene and command line for a while and it's very convenient and reliable. I want to use Corona now because a lot of people seem to like it so I'm trying to sort out an animation pipeline.

 Ill just submit a support ticket.

[C4D] General Discussion / Re: Cinema 4D 2025 + Redshift

Cinema users are kinda spoiled, like I take it you guys have never used Max? Autodesk bundles Arnold with Max but people still pay for VRay and Corona. But also Max is more than double the cost of Cinema for a yearly. Is it doubly as good? In fact you could buy a year of Cinema, corona, arnold with free redshift and it would still be less than Max plus "free" Arnold.  Just think about that for a moment. If you use Cinema over Max thats $1K to play with every year that you wouldn't have otherwise. If anything, you run Corona in Cinema you have a powerful CPU only engine, then you have redshift if you every want to try GPU.

[C4D] I need help! / VRayProxy in Corona

« on: 2024-10-10, 03:55:16 »

It looks like VRayProxy objects will render in Corona - I'm wondering if this is this going to bite me in the a$$ later?

My current options for vegetation is either to start from scratch; export max fbx, then corona proxy one at a time(can't believe we still can't do multiple like in max), build mats for each species, done. The alternative is just use VRayProxy assets. Anyone else use VRayProxy in Corona?

PS. This could be useful for animated assets since VRayProxy can take animated .abc

Bump, any thoughts?

[C4D] I need help! / Corona Standalone - lots of issues

« on: 2024-10-09, 18:38:05 »

I am trying to get the Standalone working and I've run into multiple issues:

I'm getting an error Chaos.Corona.Multipass.MaskTexMap.It has something to do with the multipass but this is pretty vague. I made sure all my multipass masks were as they should be but not sure what's up. Even if I put a blank one in, it errors. This is really maddening.

If I disable multipass masks it will render but some of my tree are missing leaves and the sun seems to be disabled? Imo, standalone really needs to be 1:1 with your 3D app output, like I thought the whole point is that you don't have to babysit it. If standalone is this unreliable I will have to really contemplate whether my short corona experiment will be a long term no-go.

Last question: does Corona standalone have operators or commands to modify render output or is it just the save file? I'm familiar with vray standalone, the corona version is new to me.

[C4D] I need help! / Re: Video textures

« on: 2024-10-03, 22:24:54 »

For the video part, yep, the technique in that OG thread still applies.

- Get that video loaded into a native C4D bitmap loader (just drag it into the node editor, Corona Bitmap doesn't support animations but the native bitmap loader does)
- Plug it into either Light MTL or the Self Illumination slot in your Physical MTL
- Render it all out.

That oughta do it :) If you encounter any roadblocks, we are here.

Is this also how you would do an animated gobo? For gobo it would have to be a light material or light object I suppose?

[C4D] I need help! / Re: Animating Exposure change not working...

« on: 2024-10-03, 22:19:47 »

For the camera to work I would uncheck all the tone map stuff in the VFB, add a photographic exposure then it should work. I would avoid any other method besides a camera change since in reality that what you would do; most likely you'd close your aperture, hence the clickless aperture ring on a lens.

disclaimer, I'm coming from vray from like last week so I might be wrong.

[C4D] I need help! / Animated asset error - Final render

« on: 2024-10-03, 22:15:05 »

thank you in advance for you feedback.

I'm working on an animated tree asset and it looks fine when I render with the IPR but when I render final, not so. I brought it in as an .abc and even baked it to PLA but its still giving me an incorrect result. The part thats giving me an error is the leaf and twig layer.

Edit : didn't see the more attachments

[C4D] I need help! / Re: Material converter Vray - Corona no maps

« on: 2024-10-02, 06:39:41 »

And not to forget that Corona can render quite a few V-Ray materials without any conversion :) You just can't edit them is the thing.

Thanks for the heads up, apricate your time. It looks like my issue is that the VRay materials I'd like to convert are Node - if I convert to VRay standard or "classic" first its all good but if they are nodes get striped of their textures. Is there any plan to have the converter work with nodes? I'd love to skip this step.  I'm sure this has been asked before but I'm new to Corona after 10y in VRay.

Hello there.
I think you might be interested in the following post, as this is a topic previously discussed: https://forum.corona-renderer.com/index.php?topic=42289.msg223090#msg223090
You can look for additional related threads here in our forums where users may have suggestions about it.
I hope this helps.
I'm sorry for any inconvenience.
Have an amazing day/evening.

I'm trying to get a sense of whether this is normal and how useful or not the scene converter is for materials. Do you have any experience with it. Honestly, the other discussion is not super helpful. The scene converter for VRay is not very useful for example, but the material one is, so I'm trying to nail that down.

Regardless, thanks for the reply.

[C4D] I need help! / Material converter Vray - Corona no maps

« on: 2024-09-28, 01:00:39 »

I have VRay and corona installed. I just canceled my VRay sub to move to Corona so I technically have both lic currently. I will be converting a lot of VRay assets during the next few weeks and when I run the scene converter - I assume this is the way - all the maps get deleted out from the scene manager and the materials only have sharers not maps.

What is the workflow for vray-corona mat conversion?
