[C4D] I need help! / Re: Scene Converter Details
« on: 2024-03-19, 23:03:38 »
Well, I managed to find an expired demo of V-ray. I was able to open this scene, took forever though. At first, when this conversion window came up, I chose to update the Vray stuff. The materials just never finished updating as they just appeared transparent (checkerboard, but if I clicked on one the beach ball would come up so it was doing something. The ones that did finish, remained as checkerboards and took a very long time. I closed it out and reopened, but this time, I chose to hit cancel on that Vray screen which seemed to work. I could see the textures in the preview spheres Immediately. Hit convert scene and overall a good job getting me close to where I need to be. This scene is a city street and a handful of items did not convert completely. Anything with the tag below was left untouched. The street material was a complex material and I was only able to get it "in the ballpark", but usable. There were a couple of cars in this scene and none of the glass materials came through correctly. Transparent yes, but like air. Tomorrow, I may go through and see any other specific Vray shaders that didn't convert in case the devs don't have them all on their to-do list.

There are light poles in this scene too and they had fake light glows created with planes, a light glint/haze and a luma matte in the Opacity node. The opacity just didn't work right, even though it seemed to be set up correctly. I played with the exposure of the matte to no avail. Seems like the leaf materials for some trees had similar issues.

LegacyVrayShader did not convert at all. You can't even see what textures were used in them either.

Would be nice if the converter had some sort of progress bar, just for sanity's sake.

P.S. I did not explore the Corona Legacy material vs. converting to Physical if that makes any difference.

Thanks Tom. I was searching in a different help section. I should've mentioned that the scene I am converting uses very basic standard C4D materials as they came in via FBX. I don't have V-ray, so couldn't use the C4D that came with this purchased model. If I did have V-ray, how close are the created Corona materials' appearance to their V-ray counterparts?

[C4D] I need help! / Scene Converter Details

I'm trying to find details on what the options in the Scene Converter tool actually do. I'm talking about:

Metalness-->Autodetect, All Metal and No Metal

Convert Shaders-->As Selected and All In Selected Objects

I see a new Cinema Bitmaps option too.

I know nothing about the Tile Shader. I downloaded the scene and I also have no bump effect. I added the Filter node. I also tried a Normal node just to see. I increased the bump to 1000. I tried UVW, Object and World. The scale of the scene looks okay to me. I moved the sun to enhance any bump effect. Also tried subdividing the object several times. I got nothing.

Was just watching the Chaos Unboxed presentation. Lots of interesting stuff coming. Since this thread is about Vantage, they also showed Enscape, which to the uneducated eye, seems somewhat similar to Vantage.

The Cosmos a.i. material generator would be amazing if it produces truly usable materials.

Very interesting. So the quality is very good in Vantage, but not production quality. It seems like a condensed version of Unreal Engine. Not sure I will need it in the future, but good to know it might be there at some point.

So the big thing is adding GPU tech to a CPU render engine. Interesting. Sounds like Unreal Engine. I would also assume that Mac users might not be able to take advantage of this tech. Not Chaos' fault, just stating the obvious. Thanks for the info.

[C4D] General Discussion / Chaos Vantage
« on: 2024-02-23, 15:43:41 »
I keep seeing mentions of Chaos Vantage, but never knew what it was. I watched part of a Chaos video and the main feature, from what I saw, was real-time (or close to it) previews. Isn't that one of the great features of Corona and V-ray, and Octane and Redshift for that matter? We have ability to have good real-time previews and updates as you work. Why  is Vantage needed if the engines already provide a similar function?

Asking for a friend. ;-)

This post doesn't make any sense to me. You are rendering a sequence with PNG+alpha as the output. That is all you need in this case.

You do NOT need the Multipass function or the Save as PSD option at all. You are not rendering any extra passes so why would you turn it on? The only time I've used multipass with a simple alpha is sometimes, when rendering objects with glass, you don't always get the proper mask with different levels of transparency/refraction.

I don't mean to sound insulting, but I would expect this post to come from a newer user and not someone that has rendered over 2,000 jobs on a render farm.

If I'm not understanding your specific situation, I apologize and look forward to seeing what is going on. Good luck.

Submitted a ticket with the log attached. I did so a basic search for the names of the materials, but did not see anything. Hope this helps.

Tom, what log file do I need to send? I opened the Console, but only see one Corona listing from last November when I installed v11.

[C4D] General Discussion / Cosmos and Vray
« on: 2024-02-18, 00:37:42 »
So I'm exploring some materials in the Cosmos browser. Oh, here's a nice looking asphalt material, let's take a look. I hit download. Perfect. When I click import, it says "You need Vray and Vantage". What is that all about? Why am I being served Vray materials in Corona? So far, I've only found two, but am surprised. Is this a mistake or is their a filter to only show me Corona-compatible materials?

[C4D] General Discussion / Re: Best Images for Dome Mapping
« on: 2024-02-14, 16:44:01 »
Thanks for the info. Yes, I did discover the indoor close-to-the-camera issue with Dome mapping. Recently, I had to show some 3D capabilities and didn't have much time, so I tried the dome mapping feature. Once you figure out the scale and height, it was pretty quick to set up a shot. I was also impressed how good it looked when I did a simple orbit camera move. Really sold the idea of a 3D space.

Just got back to this. Ah it is a command in the Corona Proxy palette. Good to know. Thanks.

I don't have the current version of C4D, but I have used the Takes system quite a bit. I noticed your paths are Relative. Could it be there is a different default in the newer versions of C4D? Is there a default setting that is expecting an Absolute path? The only other thing is I don't remember seeing brackets when using the Tokens. Is that a thing? [  ]

Just a thought. Good luck.
