[C4D] I need help! / Re: Capture Light in Multi-Pass
« on: 2022-11-30, 16:13:33 »
I came up with a solution, although maybe not the best way. I did a separate render where I put a plane that takes up the entire screen lined up with the poster. I put a mostly black material on it and compositing tags on the lights to not be seen by the camera.

This gives me a luma matte basically. I then add to the graphic and set it to Screen or Add. I also use the poster to clip the highlight effect to keep it only on the poster.

[C4D] I need help! / Capture Light in Multi-Pass
« on: 2022-11-30, 01:33:56 »
OK so if you look at this image, my task is to add the Christmas lights around the edge of the poster. I have the wires and lights, I have the bloom and glare, BUT how can I generate a layer that only has the light on the sign? I want to set it up so the sign can be switched out in AE or Premiere, but the layer with the light spots will still affect it. That make sense?

The second image points to the light effect I'd like to capture on it's own layer.

If neither of those ideas work for you, I would suggest not trying to do everything in one shot with only one tool. In other words, you can easily solve some of your issues manually. If that distant area of land should have either low-poly foliage or none, just cut the ground object there and apply a texture of your foliage. Would look fine at a distance and render super fast. You could render a still of the foliage in the distance and use that as the texture.

I assume you are also taking advantage of the Scatter Camera Clipping feature. This will at least remove all the clones on either side of the view. Just use the Extend View feature to ensure you don't get gaps or funky shadows. In fact, you can use a spline to eliminate clones in those far off area. Super easy.

Feel free to move this thread to another section since this has turned into a how can I improve this image, which is great.

Soon after posting, I kept looking at the ice and knew that was a problem. I think this render is much better. The main differences are the material on the ice was scaled up and uses less displacement. I have a light focused on the ice to brighten it up a bit, but it was too bright and the refraction went nuts. I also switched the Reflections Override with a monotone studio light image.

I was already rendering this before I quickly glanced at that article you posted. His liquid settings are basically default minus the color thing with the neck. The most obvious thing Corona is not creating since the liquid is a hard line against the glass is the way liquid creeps up the side making additional refraction effects. In a still image, that can be faked in Photoshop obviously. My liquid actually has a little more refraction than his in the article. I rendered a test with just the liquid and it it most certainly refracting.

Appreciate the feedback though.

Work in Progress/Tests / Virtual Whiskey Shoot
« on: 2022-11-28, 01:14:01 »
Set up this virtual product shot. Modeled everything myself in Cinema 4D, although the bottle is not an exact replica. I'd say the ice and liquid are an area that need a little love for realism, but over all I like this result.

The first thing that hits me in the face right away is the water. First, you wouldn't have waves like that in a pond. Second, if you did have waves, the scale of those ripples would be very small. Mostly you would see a very flat surface on the water. Then you might add a ripple ring or two indicating a bug or small fish touching the surface.

This image shows the scale of any ripples I'd expect to see. Of course, there is something creating them, so either it's very windy, a duck, turtle or fountain.

There is something off with the mountains. They look far away and too close at the same time. The night shot in particular they look wrong. Not sure what it is.

It looks very nice overall. What are you trying to "sell" with this image? The overall feel for architectural design? The interior design? Those things will affect which areas you need to focus on.

One thing I like to do is to drop a human model into my scene. Plenty to choose from in Cosmos. Assuming you have created your project to real-world scale, this should help you see any scale issues. For example, the stove does look a little small from the front, but we can't see how much space there is between the counter the stove. By putting a human that is built to scale next to the stove, if will be obvious right away.

Anyway, I like it. Adding the staircase and extending the counters against the back wall were good ideas.

I think the main issue in this render is the rocks in the foreground. There seems to be too much detail, similar to a photo being over-sharpened. I think you need to lessen the bump effect.

There is some odd lighting or shading on the house above.

My apologies. I have updated the link.

I use a Shadow Catcher material on a plane all the time with masks and alphas. If you set it up correctly, you can get all the layers separately, or you can even save an After Effects project file with everything already stacked.

I've attached a scene you can pick apart. You need to set your Shadow Catcher to Environment and Compositing. You must also drag a material into the slot provided, because if you had a white box sitting on that orange background, you would get some color spill. By making a material that matches you final background color for the poster ensures you will have the correct color that may be reflected on the surface of your box.

I've also enabled the Multi-Pass function. In the render settings, I also set it to save a Multi-pass image. This scene will give you 2 PSD files. You will have to do a little work, but not much. Just load the alpha channel as a selection and use the Float command to make a new layer based on your selection. You now have a perfect object(s) layer with a built-in shadow. The second PSD will have a clean mask just for the box in case you need to adjust the shadow.

As another option, if you select PNG as the output format, you will get all these layers as separate files. The only advantage to using the PSD format is that you could go up as high as 32-bit if you have very complex and subtle shadows and transparent areas.

Hope I didn't confuse you. Ha. That was a little rambling on my part.

[C4D] I need help! / Re: Take Manager Camera Exposure
« on: 2022-11-26, 20:08:24 »
When I use the Take system, I'll usually have a separate camera for that Take Also, don't forget about a custom Render Setting assigned to that Take as well. Might already know that, but wanted to make sure.

You didn't say you were using Team Render, so not sure that old bug is causing this problem.

@Beanzvision Do I get a prize for spotting the Pixar ball in that kitchen scene? ha

Tried your suggestion and had the same error.

@MacMDX Did you use the correct mode? I looked at the DoF and it only changed when using the one mode.

Updating a few machines so I can use my mini render farm. I logged in remotely to my Mac and I download the v10 Daily Build and run the installer. I had a similar error when v9 came out. At some point, I get an error saying there was a problem with installing the material library. It will finish the install and appears to work inside C4D, but there are errors in some of the materials from the library. They seem to be the newly added items in v10. Below is a screen shot of one section. I also say errors in the glass, nature and plastics sections. v10 installed perfectly fine on the Windows 10 PC and my 2017 iMac Pro running Monterey and an M1 Mini running OS 11.4 Big Sur.

The problem Mac is:

Version • 10 (Daily Build Nov  3 2022)
2013 Mac Pro with OS 10.15.2 Catalina (I will be updating the OS soon)
C4D r20 and r25
