[C4D] General Discussion / New Tool From Insydium

« on: 2022-03-17, 19:21:25 »

Not sure if this is a stand-alone, or an add-on to X-Particles. Looks amazing either way. Curious how this might work with Corona Render.

[C4D] General Discussion / Scatter and/or Proxy Questions

« on: 2022-02-22, 22:35:38 »

So I've come to rely on C4D's Mograph Cloners, mainly for duplicating rows of cars in a line, grid or along a path. So simple to add randomness and amazing Effectors.

I know Scatter will be far better for grass, trees, rocks and other things I'm not aware of yet. Should I switch to Scatter to clone my cars? Is it more efficient and easier on the viewport? No effector FX?

Also, right now I usually have a hidden folder in my scene with let's say 4 different car models and a copy of each one in several colors. I'll make an Instance of each one and drag those into the Cloners. Easier to select and move around. As long as they are all set to Instance and not Render Instance or Multi-Instance since those options give me problems with Corona. Any advantage to using Corona Proxy instead?

Thanks for any insights.

[C4D] Bug Reporting / Crash With Chaos Cosmos

« on: 2022-02-19, 20:02:43 »

I was trying out the new Scatter feature and had a small mountain with a tree from C4D's assets browser and 100 copies For some reason, the C4D material on the leaves wasn't rendering which bugged me, even though this was a Scatter test. I thought, let me grab a tree from Cosmos. As soon as I clicked on a tree, it shot me to a web browser, not a page, just brought Firefox to the front and C4D crashed in the background. No file was generated. I've attached the crash report the Finder brought up in case that helps at all.

I'm wondering if every time I use C4D and Corona, I'll have to go to Chaos and log in. Seems like a pain. What if I love internet for some reason? I'm screwed? If I do lose internet, what happens to the assets I previously downloaded?

[C4D] General Discussion / Physical Material and Paint Flakes

« on: 2021-12-22, 20:00:30 »

I'm trying to get good with the new Physical material system and I'm liking it. One question I have is how would I go about adding a car paint flake effect using this system? Ironically, the material library's car paint examples are using legacy materials and layers. Can the flakes be done withing one Physical material?

[C4D] Daily Builds / v8 Is Very Stable!

« on: 2021-12-21, 21:47:21 »

I'm very happy with v8's stability so far. In the past, I wasn't able to keep the Interactive Renderer or the Interactive Viewport running for more than a couple minutes before a crash. Now with v8, I have worked for hours without a crash. So much better. This behavior is with C4D r20 and r25.

Well done devs!

[C4D] General Discussion / Corona Volume Grid Animations Not Working, At First

« on: 2021-12-01, 16:57:36 »

So I wanted to play around with some volume files so I found several free VDB files on the web. Any time I tried to load a sequence, i.e. an explosion or fire, it just says "Size: empty" and nothing loads at al. From what I've read I just need to select the first file of the sequence, but nothing worked. I tried to load one of the frames and had the same error.

The solution was to delete the first first frame that was significantly smaller than the rest. I assumed this file had the "instructions" to load the rest. After I deleted this file or moved it out of the folder, the VDB sequence loaded as expected.

Hope this helps anyone else stuck on this.

[C4D] I need help! / Get Rid of Fireflies in Animation

« on: 2021-11-26, 16:40:42 »

I love Corona, but damn if I can't avoid fireflies to save my life. I will upload a scene after I post this. As you can see in this clip, I have fireflies all over the place. I will admit, on the first clip with all the trucks, I had some old chrome materials that were set to 999 IOR reflection. I fixed all of them and you can see in the single truck test, I still have fireflies in many other areas that have much less reflection. I'm assuming reflection is the main cause, but I'm only guessing. The full truck shot is using a simple Physical Sky with basic settings.

The full shot used 15 passes with High Quality Denoising. I also tried Noise Level limit of 5, 4 and 3 with either no change or even more fireflies. Clearly, adding more passes isn't the solution as far as I can tell. The step below the door of the truck is really bad. Upon closer inspection, I'm guessing the source of the fireflies there is the pill-shaped bumps, which are actual meshes and not Displacement.

I'm open to all suggestions.

[C4D] Corona Goodies - User Contributions / Free Tree/Shrubs/Plants Pack

« on: 2021-11-17, 18:26:51 »

Just found out about this site giving away a free pack of 90 (think) models including Max with Corona materials. I haven't opened it yet, but they look very nice. Just have to register, no surprise there.

https://maxtree.org/products/plant-models-vol-60/

Edit: Turns out only the Max files come with Corona materials, but all the pieces are there to build them yourself and see how close the converter gets. They are fairly low resolution textures, but the price is right.

[C4D] Daily Builds / v8 Daily Build on M1

« on: 2021-11-15, 18:07:29 »

So the latest build of v8 installs an M1-native Corona. If I'm running a r20 Team Render client via Rosetta2, is the render engine still running in M1 native mode and theoretically faster?

[C4D] General Discussion / Noise Level Question

« on: 2021-11-10, 00:13:12 »

I'm curious. Is the setting for Noise Level a smart system where it applies more light rays or passes to certain noisy areas, it is it a blanket system? So if the noise level renders with 25 passes, is it the same as me manually setting the passes to 25? Just curious.

[C4D] General Discussion / Avoiding Sky Pinching

« on: 2021-11-06, 21:50:47 »

So I'm testing a scene for a shot in a commercial. It is only lit with an HDRI in a Corona Sky object and no Sun since I was getting nice lighting and shadows. What is the best way to avoid the "pinching" of the sky in the reflections? This includes trashing this setup for something completely different.

Running v7 Hotfix 2.

I see Dome Mapping is now supported in the latest build. Why do I want that?

[C4D] General Discussion / Hotfix Question

« on: 2021-10-20, 06:25:35 »

A friend of mine that I got him into Corona, might need to send a job to a render farm. He was running v4 of Corona so told him to update the latest Hotfix 2. He informed me the render farm (not sure which one yet) supports Hotfix 1. Knowing he's not using a specific tool that only appeared in Hotfix 2, would he get into any issues rendering a Hotfix 2-saved scene on a Hotfix 1 render farm?

I know he can install the older one, but if he really doesn't have to...

[C4D] Bug Reporting / Crash When Replacing Materials

« on: 2021-08-07, 03:52:18 »

I had previously posted about a crash when dragging materials from the Content Browser to the Material Window. Not sure if this is the same error or not. Now, I've had a couple crashes when running the Interactive Viewport.

I paste a car model that has C4D materials into a scene that has existing Corona car materials. I like to drag the window glass Corona material on top of the C4D glass material using the alt/option drag feature. This replaces the old material with he Corona material everywhere it is used. Very quick way to set up my model for rendering.

Even better is to use one of the interactive render windows to get real-time feedback. This type of crash seems to mostly happen with IR running.

I've attached the bug report and something called trigger. For some reason, C4D hasn't been creating the scene file.

[C4D] Daily Builds / Release 7 Missing DLL Error

« on: 2021-08-05, 16:42:15 »

Not sure if this is the right place to post this question, but here it is. I'm a Mac guy, so these errors stop me cold since the error is not specific. I installed r7 on my other Windows 10 renderbox with no issues. On this Windows 10 installation, I'm getting this VRCRUNTIME140.DLL error. My first question, is this telling me that reinstalling the Corona installer will fix this? I also got this error when unpacking the ZIP and running it from there, so I'm confused on how to fix this.

Any suggestions is much appreciated.
