[C4D] General Discussion / HDRI Lighting
« on: 2023-03-18, 13:40:23 »
I have noticed over the years that many times when you grab an image to use for lighting, it may also come with a low-res blurry version called Environment, a medium res clear version-2k usually and one large file coming in a 16k or so.

What is the proper use of that small blurry file? Environment override? What's the advantage of using the blurry image versus just letting the sky provide reflections?

[C4D] General Discussion / Affordable Render Farm Services
« on: 2023-03-13, 21:32:11 »
I know there are some posts about farms, but they're all over the place and many are very old.

I have some architectural type animations I need to do. Static room and simple, slow camera moves. It's just too much for my old iMac Pro. A 10 second move can easily be 24 hours with moderate number of passes and denoising. There is a long list of farm services on Corona's web site. It's a little daunting. So far, Rebus is the only site that I can input my exact CPU. The others I have to guess a comparable chip and fingers crossed.

For Corona peeps that have used farms, what is your top five companies I should look at for price/performance? I assume I'll have to be careful with shared textures and the Corona Bitmap problem.

The other question is, I have been using the daily builds, but not using any specific feature of v10. In the past, I have rendered newer Corona version on nodes with a lesser version of Corona without problem. I'm sure I could go back to v9 and save again. Thanks for any advice.

Gallery / Endless Engines Community Challenge
« on: 2023-03-12, 22:46:43 »
I didn't find out about this challenge until two weeks ago, but I managed to get something together by the deadline. It's put on by Clint Jones (goes by pwnisher online), formerly of Corridor Crew. Great YouTube channel if you haven't checked it out. They break down all sorts of VFX shots with industry experts, have their own in-house challenges and great how-to videos. Any way, Clint has does these in the past where he provides a starter scene with some elements that needs to stay mostly intact, but you can do anything within that space. Their are only 120 frames and he strings them together into a super long collage. Then they pick the top 100, then the top 10 for prizes. I didn't have much time to put into this, so I chose a theme where I didn't have to rig a car or character, mostly straight out of Corona v10 daily. I added a little smoke and exhaust fire FX in AE. I also chose a nostalgic theme, at least here in America. The young Boy Scouts will make these wooden cars called Pinewood Derby with a kit and certain parameters and race them against the other scouts' cars. Gravity only so they have to think about aerodynamics and weight distribution. I built these cars based on the cars I helped my son build. The red one got second place overall.

This is my entry. This clip loops four times. My idea was the cars are racing on their own when nobody is around. Fun and good practice. If you search YouTube for Endless Engines, many of posted their entries. Lots of creative stuff.

[C4D] I need help! / Odd Motion Blur
« on: 2023-03-11, 22:33:26 »
I know there are some lingering motion blur issues floating around, but didn't see this one coming. This is a closeup of a wheel that is rolling and moving to the right. It looks like I'm getting just horizontal blurs instead of radial. Could it be the forward motion is greater than the rotational?

These are also displaced, white tire lettering if that makes any difference. I'm going to jack up the rotations to see if that changes anything.

[C4D] General Discussion / Problems Updating Payment Info
« on: 2023-01-17, 20:18:26 »
So I have already reached out via the help link on the 2Checkout page yeasterday. The responses are slow and my subscription is set to expire today so I'm posting here too without personal info.

The form refuses to take my new American Express card info. Keeps saying "Invalid Card Type." Their first advice today was simply to clear the cache and try again. Nothing. I replied, but I may not hear anything until tomorrow. There are three credit cards listed on the payment form, JCB, Carte Bleue and Dankort. That's it. Now I'm stuck.

Any advice on this?

[C4D] Resolved Bugs / Possible Bug
« on: 2023-01-07, 01:22:32 »
I have a project that I want to render on my small farm. I Save Project with Assets to ensure I have everything since this will be on another network.

Since this is an animation, I always like to pull up the texture manager make sure I have all green checks. Well, there are a bunch of materials that apparently didn't make the trip. I do see the word "shared" quite a bit in there. I believe every material in this scene is from the material library or Cosmos. Perhaps one or two I have a PBR set for. Nothing complex.

It is also possible that any missing textures may not be in the view of this camera, but didn't want to take a chance.

Is there a workaround for this? I would imagine this is a big problem for anyone sending their project to a real render farm.

Just realized I have Version • 10 (Daily Build Dec 20 2022) on the remote Mac. Doubt that would cause this though.

[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.

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.

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:

Found an old C4D scene and finished it off with Corona. I need to learn more about adding some subtle fog to this scene. Maybe play with depth of field too. Enjoy.

[C4D] Resolved Bugs / Decals Don't Work with Instances
« on: 2022-11-20, 19:17:49 »
Main issue. It appears Decals do not work with C4D instances at all. Tried Instance, Render Instance and Multi-Instance. If I just drop a stacked material onto the objects, the grunge shows up in all instances no problem.

I thought, why not try this Corona Proxy object instead of using C4D's Instances. First of all, very clumsy to use. Multiple steps, save each one, blah, blah. Should just work with a click. As you can see in the lower image, not quite the look I was going for. I have read in other old threads, that you need to combine into one mesh and drag materials into those channels. What goes where? I have no clue. Clunky. If you have a bunch of houses or buildings this would take so long.

Anyway, Decals don't work with Instances.

[C4D] Bug Reporting / Problems with Takes
« on: 2022-11-05, 00:28:47 »
I'm not certain this is just a v9 issue or not, since I haven't used the Take system in a bit.

If the Corona preferences are set to always use the VFB, the command Render Marked Takes doesn't seem to work. It seems to be rendering somewhere because if I hit render again, it asks if I want to abort the current render. Not shows up on my drive however. When I switched the preferences back to C4D's Picture Viewer, everything worked as expected.

Also when rendering multiple takes, I keep getting the window indicating I am missing all or most of my textures, but nothing is actually missing. When I continue with the job, rendering is as expected with zero missing textures. Rendering the same scene with a simple Render to Picture Viewer gives me no warning and also renders as expected.

Not sure what's going on there.

[C4D] General Discussion / Does Scene Converter Work?
« on: 2022-10-26, 18:11:03 »
I have stayed away from the Scene Converter since it does such a poor job with Reflectance, and have just built new materials with those assets. I saw a new Kit Bash collection I was interested in, but they currently don't offer Corona setups. They do have C4D and VRay. Any chance Corona can covert Vray into anything useful? If yes, would I have to also own Vray, which seems silly?

An entire Kit Bash would probably have hundreds of materials that makes it daunting to convert to Corona.
