How to render Cinema 4D Pyro in Arnold Renderer! (Quickstart)

[@misterdoctor9688]

Hi. I didnt get. I have the same version of arnold, but first render looks totally different, theres only smoke in ipr, no fire. U can see this even without volume material. How?

[@the-astropath]

It's hard for me to diagnose without more information.

[@the-astropath]

Make sure you're pyro object settings are the same as mine.

[@misterdoctor9688]

u didnt do any changes in your settings on 1:10, but still can render pyro even without volume material. i did the same and theres no fire fire in my ipr, i can see only smoke if my quad light has 10 intensity and exposure

[@ssjenforcer191191191]

@@misterdoctor9688 same here. I only have smoke no fire. When I started doing the exact same things in the video my smoke was white-grey when his was immediately the colour of fire. I don't understand as I did everything EXACTLY the same as him.

[@rorycchan]

i have the same problem… it appears only smoke…

[@ssjenforcer191191191]

I was finally able to get my render to work, but the IPR window is totally bugged for viewing pyro. I'm not sure how you got yours to work, but my IPR window doesn't show any colour other than the smoke. The fire renders fine but there is no colour for the fire in the IPR at all; only the smoke colour is visible in the IPR. I did everything exactly the same as you, but my IPR cannot see the fire.

[@zahid_bhat]

try caching it and import the vdb files in the pyro object and see if you see the fire in ipr

[@mouaadjaaidi5011]

You need to apply to it (to the pyro object) an Arnold volume Cháfer. Then, enter that shader and check the channels it's accessing. You'll see that for the color/temperature field the channel is "heat". There's no heat channel in Pyro. So just remove that and write "temperature" so the shader will access the pyros's temperature channel. It's just a naming convention mismatch, it happens a lot when using .vdb from different sources that use different names for their channels. Hope this fixes your "bug".

How do did you manage to get several colors like in the intro with the orange and blue? I also want to multicolour my smoke but I find it difficult. Thanks for the tutorial!

thank you

[@the-astropath]

You're welcome :)

Dear Mac Users: Do not try this on a Late 2015 iMac with i5.

[@thewayne9747]

Thank for this tutorial, but at the end when I cache, like you did for make the last render, it's still black for me, how I can fix that ?

[@the-astropath]

Did you select the vdb sequence?

[@thewayne9747]

@@the-astropath yes

[@thewayne9747]

@@the-astropath yes I did that

[@thewayne9747]

@@the-astropath at the beginning in the viewport everything works, but as soon as I go to cache it as you did in your video for rendering, nothing is displayed when trying to rendering the frame

[@the-astropath]

@@thewayne9747 It's hard for me to help without seeing the project file. You can always read the Arnold documentation for all the details. That's what I used to learn.

more Arnold ! tutorial pls i subs

[@muser7935]

Onley smokes appears in IPR. what is the issue >>> thanks for this tutorial BTW

[@PD-ws4td]

In the volume shader, under "emission", you'll see something called "channel" where it is written "heat". Simply rename this "heat" to "temperature" and the problem should be fixed.

[@theterifique9727]

When i cache my sim it just disapered. You you help me please ?

[@the-astropath]

You have to select the .vdb sequence you cached. That way it imports the whole sequence.

[@theterifique9727]

@@the-astropath i go in file name and select the first vdb exported in the cache section, and it doesn't work. That's sooo weird, i searched everywhere on the inernet and followed step by step each tutotial but nothing.

[@theterifique9727]

@@the-astropath that's the error message: [volume] IoError: could not get size of file C:\Users\Shadow\Desktop\Nouveau dossier\Scène de simulation_0000.vdb

[@the-astropath]

@@theterifique9727 well what's the file size of the vdb it should be decently large. If it's only a couple KB something happened when you cached probably.

[@theterifique9727]

@@the-astropath well the biggest one is 250 000ko. I don't think that's the problem. I updated everything too.

I love ARNOLD

[@jordanwright5795]

This is absolutely fantastic. For so much of my client work I have to use Redshift as that’s part of the pipeline many of the agencies I do work for have shifted to. When it’s up to me or when I do personal work Arnold is by far my favorite renderer to work with. It’s great to see Arnold get some love here. The pacing, clarity and conciseness of your tutorials is perfect. Exceptional work. Liked and subbed.

[@the-astropath]

Thanks Jordan, more Arnold videos to come :) I agree, I think Arnold get's looked over a lot because it's not pure GPU render engine like Octane or Redshift.

[@kalootmultimedia7989]

i dont know how can i select the .vdb sequence that cached....would you please tell me.... becouse my render is turn out black also...

[@limell1704]

Я так понимаю pyro на arnold рендерится только на cpu? Нельзя никак на gpu сделать? А то процессором же долго будет

[@Namirov_V]

Thanks bro ! Now not need more buy redshift - you safe my money !

[@22carmoon]

Bam! Straight to the point. Learnt alot from this tutorial, thank you.

[@salahdaoui-l4u]

Thx

[@chrismiless8300]

pls make more arnold tuto

[@the-astropath]

More on the way!

[@lightning4201]

Ty. Glad to see Arnold getting some love. Don't think it's talked about enough. Great tut.

[@the-astropath]

Arnold is one of my favorite renderer's.

[@lightning4201]

@@the-astropathHaven't used a lot of them but it is my favorite thus far. Do you find it a bit slow compared to other GPU renderers though?

[@the-astropath]

@@lightning4201 Yes, it's generally slower than redshift or octane, but it has it's benefits.

[@AswanthaDomainCreates]

Arnold pyro is not working on GPU rendering. Is there any solution?

[@the-astropath]

I used the CPU for this render. Arnold GPU doesn't have all of the same features as the CPU.

[@AswanthaDomainCreates]

@@the-astropath thanks 🤝

[@art_means_artificial]

why arnold? and how to get rid of noise in arnold for animation?

[@the-astropath]

Because I love Arnold too :) more Redshift videos are coming too. There are a few ways to address the noise in Arnold. Increasing Camera AA samples is the easiest but I'm going to go over more details in the next video I put out.

[@lightning4201]

@@the-astropath I also find I get noise more in my animations; I am using the GPU render though so if you have tips that are not going to drastically increase render time, that would be great. Thanks for al you do!
