Now this is the kind of open-ended theme that we can all shoe-horn whatever we want into that I like to see! :joy:

Looking forward to seeing what you all come up with!



I’ll try and get more done soon :smiley:

Just a quick update (ahem, took 1hr on my old card!!! I never used to need a good graphics card! Scouted something, new card coming soon, then I’ll have a real play)

Good to see you all, have fun!


You’re right… Didn’t see any of that in the atmosphere

THAT has been a hell of a break:
Welcome back! :slight_smile:


I never really left, but only celebrated my 2.8 birthday yesterday…

Moved into 3d printing and cnc routers so simply not been rendering.

So many keyboard shortcuts have changed, I’m all over the place.

Hope you all well and I have missed the Weekend Challenge dearly :smiley:


Volumetrics in Cycles is sooo awesome. Okay they really are awesome but…

First cloud setup at high definition was going to be a 21+ hours. Reduced the definition and went down to 13+hours. Reduced again and now down to about 8 hours. I am at the 6 hour point of rendering so hopefully done soon.

@rarebit, what do you normally carve on your cnc?

Cycles, 3000 samples, smoke physics, default ivy generator, filmic, vignette and name added with Paintshop Pro

Simple setup of 4 smoke flows in one domain and then strategic point lights plus a very long render time. Volume step size finally set to .03 and resolution definition set to 200 and high resolution to 2. Cloud material set to blue and lightning to red. All purple color is from their interaction.



Pure entry, 1000 samples. Turned out OK, had to ignore a little speckle on one of the clouds after messing with the lighting. Despeckling almost got rid of it, but also ruined most of the image, so I left it alone.

So proud of my cloud :slight_smile: Thanks to one of @Iridesium’s YouTube tutorials.

I’ll be doing clouds this week!

Hi @rarebit, welcome back :slight_smile:


Didn’t realize it was that long since you been on. :sweat_smile:
Been a while.

I was think something a little more intense for the the eyes to see in my render when I start on it tonight. :eyes:
I’ll be working on two projects tonight have to finish one of them.

I’m going to come at it from a different angle. :speak_no_evil::v::face_with_hand_over_mouth:


Eye candy! Can’t wait to see the awesome render. :smiley:

Ooohhh :speak_no_evil: you cought on to my riddle didn’t you. :sweat_smile::face_with_hand_over_mouth:

You can use color corrections, and filters in the compositer to get some variations of your render.

As far as the eye can see. :see_no_evil::grin:

I have an extremely ambitious idea… Pretty sure I’ll not make it on tome, but we gotta try, right?


PURE “rain”
I was forced to not use volumetric due to extremely long render times so it is not as accurate I intended.
Cycles 128s


quick update:


You can put a square over the field and can use prinapaled volume bsdf and put it in the volume connection it works faster than the older blenders I just used it this morning and I was like. :scream_cat::drooling_face::dizzy_face:
Then you can go in the compositer to do fog if you need to make ajustments.
You can put a color gradient texture into a colorramp then connect the colorramp the the principled volume shader then connect it to a mix shader with layer weight facing connected to the factor and another volume connected to the bottom then run into the volume input.
You will have to put a rotation on the gradient incase you need to rotate it. :v::+1:

Thanks. It seems to be easier than that i have used :wink:

You should see my pre render scene it looks awesome. :v:
have a little to much going on in the compositer will have to make a few adjustments to it. :grin:

I thought it was real for a second and i realized I modeled it. :sweat_smile::face_with_hand_over_mouth:

made in cycles as a displacement map. :slight_smile:
render : 30 minutes
sample 500

here a fix all problem with first one
