[C4D] I need help! / Re: Help optimising a scene (40 mins/frame)

« on: 2023-05-10, 21:49:39 »

I always use denoising. But I will look at specifying passes instead as there are some frames in the middle of the animation that take double the time, which is probably to do with my noise specification.
Thanks for the tip.

Thanks for your help. Things are speeding up.

I'll remove the SSS on all but the rubber elements next time round.

What do you mean by 'lower the MSI to 1'? Where is this?

I've just completed a short render of a simple product of a plastic fume cupboard. For reasons I don't understand the frames were taking as long as 40 minutes each (res=1080p). Even the fastest frame was 15 mins. I thought maybe the caustics of the glass were responsible so I removed them. Luckily I didn't need my computer for three days! But now that it's rendered I'd like to understand if I did anything stupid to make it take so long to cook each frame. Just in case the client has any change requests… I appreciate that on Apple Silicone Corona is running in Rosetta so it's not as fast as it has the potential to be (right?) but even so I thought I'd have better performance.

[C4D] I need help! / Re: How to use the Wire Shader?

« on: 2023-04-03, 08:00:27 »

I saw that help page after I posted. But I still don’t really know what it’s for. Why might someone use it over say, rendering the viewport?

« on: 2023-04-02, 23:54:05 »

I've just discovered there is a Wire Shader in Corona, but I've no idea what it's for. There are a few posts in this forum but would appreciate some tips on it if anyone can advise on what it is designed to do, or how one might use it.
Thanks

[C4D] Feature Requests / Smarter Cosmos library - thoughts

« on: 2023-04-01, 22:08:16 »

I appreciate the convenience of Cosmos materials and objects at my fingertips but find it a little basic in its current form.

For example if I want to search for a 'plastic' material I get zero results. But there a plenty of objects in there with plastic materials that I could 'borrow' from. Some more property tagging would be helpful.

Also, having massive thumbnails of the materials without text is nice to look at, sometimes I want to READ what the material is (especially for wood materials) so I can choose by name as well. The same way that C4Ds material panel allows me to view by material, or material list etc.

What's New shows me stuff tagged with December 2022 content. Which isn't that new really. Especially as there were a bunch of humans added in 2023. But if I type 2023 I get zero results, not April 2023, but only april2023. Some smarter search functions would be welcome.

Also I can't 'select all then 'delete'' in the input field to delete my entry. I have to manually backspace my entry like it's the 1990s.

I'm suer I have more ideas....

I’ve tried that but it bounced back.

I've been a user of the Corona Materials website ( www.corona-materials.de) for ages. Although Cosmos has some good materials browsing in Cosmos is really poor user experience so I'd often pop over there and grab what I need from the site instead.
After my holiday I popped back to look for a specific material and see that the site is pretty much broken. Is it an 'unofficial' site? Is it being shut down? Would be such a shame.

[C4D] I need help! / Re: Art on soda can material question

« on: 2022-12-08, 10:18:21 »

Physical materials all the way. I think I'll try to stack them, as I am not getting quite the right balance of reflective metal on the top of the can, and the more matt white on the artwork. My art is in the Base layer, that's the right place to put it isn't it?

[C4D] I need help! / Art on soda can material question

« on: 2022-12-08, 09:14:09 »

Hi — There are some good metallic base materials in the General material presets. I have some White artwork on a metallic soda and am not getting a good result just fiddling with it. Where would I put my UV'd bitmap artwork as a rule of thumb? Base later Texture channel? On Octane it goes in the specular (according to a video I've just seen), but I realise they approach things differently. Thanks

Thanks for your help and explanation, but I think you have shared the wrong file with me. That JB scene doesn't have any multi passes set up

Adding the Floor material to the Shadow Catcher's Environment is something I missed. But I'm still not getting quite the right result. It's getting closer, but the single output file doesn't have the scene alpha.

I just realised I add the shadow catcher as a second material on top of the background material. Not sure where I was when I was supposed to be learning that!

Your answer is how I expected to do it, but I must be doing something else wrong because it just doesn't work like that for me.
The shadow catcher is set to 'For compositing' but it creates artefacts where it intersects the floor in the Beauty pass. And when I use a mask it isn't a string mask but a multi coloured thing.

UPDATE: Just realised I set an Object ID and not a Mask in the MultiPass setting. So have the Glass mask sorted. But the contact shadows still escapes me.
