Cycles render with volume to capture god rays


My first time rendering with volume after upgrading my PC, render time was 2 hours with 3000 samples with Cycles.
it still need an denoise process.
but so far i’m satisfied.
i don’t if it’s good not not good enough, i’m hoping for inputs, thanks.

and also made an animation out of this model too, but rendered in Eevee.

extra.
if you want to see how i painted the model and rigged it, here’s my video.

I really like this!

I like the still image, it’s very good, but I have one small problem with it. I see a light source behind the dragon, like a cave entrance, yet the god rays are from a light source in the upper left of the image, which can’t be seen.

Maybe I’m just over analyzing things…

The first animation looks amazing! You should seriously think about rendering that out as a full hi-res video.

How did you create the dragon? What software did you use? I ask because I’ve been working on a serpent myself and would love to know how you create it.

Great work!

i know right? i use hdri from blender folder though, but the light came out and bouncing everywhere.

you are right about cave entrance, i made it that way.

for the hi-res video i included it at the end of this video https://youtu.be/v0qY8JPs6ls as bonus clip, i can’t post the hires video on this forum, max .gif 5mb

i made the dragon using zbrush, i needed the details like this


i can’t sculpt high details in blender, it’s too slow.

Hi there, I believe your first Cycles render doesn’t worth the two hours you needed for it, you can get very good results with Eevee with a fraction of that and using volumetric effect too.
I believe the picture will work best if you remove (or reduce) the fog effect on the left side of the image.
I really like the first video, it is really good.
On general, if you add a bit of post, this can come out with great result. Great job!

i rendered on the first run with 200 samples, and noise on the god rays was like old tv.
i did try it with eevee first, but eevee didn’t deliver a good result with indoor or maybe i need to spend more time with eevee.
about the fog that would the anisotropy, so confuse with it.

Thanks for the info! And thanks for pointing out that the hi-res video of the animation was at the end of the video links you posted.

I’m really impressed! Not often that I would say that, but that’s really good work!

How many hours did you spend on the dragon? I mean I see a lot of sculpting work, then you’d have to retopo and paint, then rig it as well.

Thanks for sharing!

thanks.
for that model, head, scales, fins, teeth, neck around two weeks, i was gonna go for whole body, but i calculated it’s going to ttake a month, so i stopped at the neck.
depends on the details, just look at the reference images, i always use pictures of lizards, look at the scales, how it formed, analyze it, that’s how you know how much details you need.

the reason i rigged it, because of my goal was to render it with posed model and animate it for short clip, thanks to eevee, very powerful render engine on dark environtment.

In Cycles, it’s better to render volumetric fog as a separate pass (with the solid objects as holdout). Volume fog can be denoised much better and at a lower sample count when it’s not mixed with a background.

how do i seperate volumetric render pass?

Here is a video that explains it. This one goes one step further and renders the volume pass in Eevee, though you could do the same technique with Cycles.

This video is more or less just step by step instructions, but passes and compositing is actually a rather broad topic, an entire sector of 3D art just like modeling, animation or rendering.

If you want to understand what is happening in this video, you would need to learn about view layers, Blender’s scenes system, rendering with transparent background / holdouts, and the compositor.

How you make the link appear like that? It is a html code insertion? Because it looks different…

  1. Upload the image for thumbnail first, and copy the code…


  2. Click hyperlink

  3. Insert the address in the first field, and paste the uploaded image code in the “optional title” field


  4. Result…
