Title: Maru's random stuff
Post by: maru on 2016-07-19, 14:45:49
Removed the old thread since it was reeealy old.

Starting with a Corona fractal which is also a movie reference. I wonder who can guess what movie that is. It's also an image straight from Corona's VFB without any other post processing.

I know nothing about the movie, but your fractal is looking freaking cool. Gotta play to Corona's fractal someday :]

It's the often overlooked CFractal I believe - head to Add, open up the drop down, choose Corona, and the CFractal option is there. Overlooked I think because it doesn't have a practical value, but it sure makes some nice images and is fun to play with!

You can even stand inside them if you like if you use the Corona CameraMod for a stereoscopic panorama, quickie I did for fun attached!

Hah, that's crazy Tom! Never thought of that! I'll surely check it our with a VR viewer.

Maru how did you create such big image attachment in the forum ? i imagined the biggest was always 1024 pixels wide maximum.

Looks like the only limitation is 15mb file size. I just attached it, so it should work for everyone, unless I have some special forum privileges regardng this.

ahhh the 1st Megatexture/model megaspa, great picture, but this vanilla fog flavour is quite strong. It reminds me a little bit to the following clip, although it is german, you guys will smell the spirit.

It wasn't my intention to make it photoreal. I was just pushing VFB post processing to its limits. That's why I called it "Instagram" look. ;)
Title: Re: Maru's random stuff

I don't think it's Corona's post processing limits, but i'm affraid to imagine what to expect from you when Ondra will give us curves :]

Hmmm....why does this remind me of the movie-Jumanji? Is this a subtle advert for the new version of this movie? Is Maru working with the makers of the new movie or something?

Nice work, maru.

Testing scatter in Corona 1.5. ;)
No post processing outside Corona's VFB.

Random comeback! As usually straight from the vfb with no other post-processing. Basically a few Corona Scatters then some LightMixing. Everything is 100% procedural. The fog/clouds are fully 3d with a volumetric material.

Inspired by a movie I saw recently. ;)

Yup!

It was basically a plane with displacement, and a distance map to drive it away from buildings.

Actually I think I can share this scene. Stand by...

"... a distance map to drive it away from buildings. "

i am interested on this one. does this translates on c4d corona as well? i was wondering, how did you make this natural looking fog all around artefacts (buldings, etc)

Pure Corona. It's a metal-like material covered with a thin layer of glass with dispersion enabled. You can get a lot of cool effects with this (though hard to control). I'll post some more examples soon.

We are planning general forum migration/overhaul at some point, so who knows what magic will be available then.

Playing with the new bokeh. It seems that's it's a bit tricky to find the sweet spot, but here is center bias at 0,5 and vignetting at 2.

My head is spinning :] Marvelous bokeh! Now we need onion rings, dust map and CA and bokeh in Corona will be nearly perfect! ;]
By the way, my findings were similar, something of 0,5 bias and 1-1,5 vigneting gives "optimal" result.
Title: Re: Maru's random stuff
Post by: zuliban on 2018-02-10, 20:25:43
one of my most wanted features looks great ! my only observation is the ring around the cat eye get only half of it instead of the whole form other than that looks practically the same as a camera.
Title: Re: Maru's random stuff
Post by: romullus on 2018-02-10, 20:35:36
I think it's actually how it should be. It's called optical vignetting not without a reason. Here's couple examples where that phenomena is clearly visible:

Yes, to me it looks quite correct.
Also the ring bias and vignetting are controllable in + - scale, so it could be possibly tweaked to resemble some real life lens better.

@Romullus - what are onion rings? :O
CA would definitely be a good addition.

Post by: zuliban on 2018-02-10, 22:41:03
yes in the images half of the halo ring is stronger but still the other half has the ring on it and is hard to see it ,in the render it only show the half of the ring and the other half has not a weaker halo.
Title: Re: Maru's random stuff
Post by: romullus on 2018-02-10, 22:53:12
I think it could be just because maru used quite strong settings for optical vignetting. If you would use <1, then it probably wouldn't cut off those rings that much.

Love that addition, I had to keep 10,000s individual instances of rivets and screws in some scenes to get some randomization, looking forward to being able to collapse them now.

Well, the current workaround was to distribute random material IDs (Material By Element modifier), but now it's just much more convenient. :)

Some autobump tests. The cave wall is a procedural material with displacement and bump.

RAM usage:
Autobump off, displacement size 1px: 11,6 GB
Autobump off, displacement size 4px:  3,4 GB
Autobump on, displacement size 4px: 5,2 GB

Note that the quality of autobump off 1px is _similar_ to the quality of autobump on 4px, while the RAM usage is 11,6 GB vs 5,2 GB.
