[C4D] I need help! / Re: Lights and Glows in Masks
« on: 2024-12-17, 01:43:04 »
Sorry for not updating this thread, but I had to meet the deadline so I came up with a workaround. I removed those large marquee Light Objects and replaced them with Spheres and a Light Material. This got me a workable mask. I'll have to revisit this now that I'm past this deadline. Thank you for replying though. Object IDs is something I've not learned about. Also that mask technique that creates a pass with flat colors that allows for easy object selections without masks.

[C4D] I need help! / Re: Random flashes with Corona Sun

Ha, I was going to comment on your dilemma, then realized the link pointed to my post a while back. Too funny. In addition to using the Clamping feature, I also had some IOR settings set to astronomical numbers. That was based on an old tutorial I followed. Not sure if this is mentioned in my old thread or not. You have to be careful with the Clamp setting though. You can remove too much of the highlights if you're not careful.

I also remember something about using an HDR vs. just a Sun and Sky object. Good luck.

I too have wondered about this as it doesn't make sense when using the Post Effects tab. I understand some new calculations, but to start from scratch every time just doesn't seem right.

I did a quick test with native C4D visible lights, Mograph and a simple plane and it works as expected so this issue is Corona or me. ha

[C4D] I need help! / Lights and Glows in Masks
« on: 2024-12-02, 17:23:09 »
I need a little advice. I have this animation I'm working on. This truck will roll into the shot and end like this. There are also cars on the truck. I'm trying to render the truck and cars separately so I only have to render the truck once, and I can switch out the cars as needed.

My issue is I can't get the lights or the Bloom and Glare included in the mask. As you can see more easily with the large banner and the bigger lights, they only appear where there isn't the alpha channel. I have tried so many things and can't get this to work. The lights are placed along splines via a Mograph Cloner, however, I've tried converting the Cloner to individual lights with the same result.

Any ideas what I am missing?

[C4D] Daily Builds / Re: Who has the Mac M4 pro or max
« on: 2024-11-12, 16:30:14 »
I don't like hearing "almost as fast as my M1 Studio Ultra." I know it's "Ultra", but three chips later should not be a competition at all.

Any chance you do my favorite old-school test, Grapes render test? That scene is in the browser. Just pure CPU rendering. Open, Render to Picture Viewer. Post render time. These new benchmarks are difficult to decipher for my brain. ha

[C4D] General Discussion / Re: denoising cpu
« on: 2024-10-21, 23:14:52 »
Maru, if the Denoiser switches between CPU and GPU in a mixed render farm or Team Render setup, is there a risk of flickering with different noise patterns? Just curious.

23
Is that a built-in script, or one written by a user? Would be nice if the C4D Remove Duplicate Materials worked with Corona mats.

Isn't Corona a CPU ONLY engine? Why would a CUDA driver cause an issue with Corona? I am NOT a Windows expert, just know enough to ask.

[C4D] General Discussion / Re: CoronaCore has crashed
« on: 2024-10-11, 23:39:43 »
This happened to my once, but that scene wasn't important so I recreated it. You already tried one trick of mine, so I'll suggest another. I would also send the Devs the crash report if there is one.

Now in the old days when you had a System Extension causing a crash, the easiest way I knew to narrow it down was to remove half of the extensions or in this case, half of the objects in your scene. Just delete half and hit render. If it still crashes, then the cause may still be an object in your scene. Delete half of the remaining objects and see if it crashes. Keep doing this until it renders. That means the offending object was in the half you just deleted. Hit undo until that objects come back and  inspect carefully or delete the OTHER half, and then again half of the remaining. Repeat. You might find something.

One time for me, it was a single point on a mesh that somehow was a few thousand units off to the side. So stretched out I couldn't even see the polygon. After I realized that and deleted that single vertex, boom. Rendered just fine. It's like it was out of bounds or something. Select of your meshes in Point Mode and select all to select all the points in your scene. Zoom out to look for any points that a very far out.

If the half method doesn't work with objects, could be a material that is doing something odd. You mentioned memory, but you didn't mention how much your system has.

A final point would be is there is no reason for you to be using v8 of Corona Render. Why? Generally speaking, it has become more stable as time has gone by. I know on my Mac system, the Interactive Renderer was unstable and I would stay away from it. The Interactive Viewport was even worse. Now, I can mostly use them both and pretty decent almost real-time rendering. I'm sure if I install v8, it will crash a lot.

Also, if you are simply testing the animation and not the render quality or speed of Corona, then of course you can hit the Make Preview option in the Render menu. You can easily render a "pre-vis" style animation which will give you the real motion and timing of the animation, but at viewport quality.

[C4D] Bug Reporting / Re: convert scene opacity error
« on: 2024-10-11, 20:03:33 »
Oh okay. You got me excited for a minute there that changing the engine makes the conversion better. It is sad that there hasn't been much progress in converting standard C4D materials. I know they still render, but I'm sure we are not getting the same results as if the material was built in Corona.

Tom, changing the C4D engine to Physical is something I haven't heard before. Are you saying if I have my Corona scene, import C4D materials, change the engine to Physical and then Convert Scene, or should this be done in a separate scene BEFORE bringing in the materials into the Corona scene?

Just throwing this idea out there. What if you set your scene with LightMix. Render the one animation in daylight. Then change the lighting in the LightMix panel and export the night version. I assume you can do this, but you'd only have to render once and transition in a video app between the two. I have not used LightMix for an animation, but I think that can be done. LightMix is pretty powerful.

I have had a similar issue, but it was always the Interactive Viewport. I opened your scene and viewport render, interactive viewport, picture viewer and VFB all matched.

The Linear Workflow Shading was ON for me. When I turned it off, then the issue showed up. Interestingly, previously for me. it was always an older project file. If I copied everything, created a blank scene and then pasted, this problem went away.

Maybe the Linear setting was a default at some point.
