Maru's random stuff

[maru]

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.

[alexyork]

Lovely. Reminds me of this:

[romullus]

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

[maru]

Lovely. Reminds me of this:

Bingo! :D

[TomG]

A fractal Lament Configuration! And looking quite lovely too.

[maru]

VR with DoF? No problem! ;)

[steyin]

Just don't 3D print a puzzlebox, just in case.

[mferster]

Cool, how was this made? displacement?

[TomG]

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]

Straight from the V-F-B!

[romullus]

Now where's my Italo Disco cassette... :]

[zuliban]

looks really nice and retro the last time i saw something similar was a far cry game

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

[lacilaci]

Nice one. Looks like that dubcat logo.

[maru]

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.

[maru]

Random thing. All procedural, and without any non-Corona post processing.

[Ondra]

yeah, I see a thing in there. But maybe it is just my smutty mind :D

[TomG]

Perhaps HR Giger is an influence on Maru's work? :)

[maru]

:P

Well, you see things in nature!


The original idea was to create a rock like that with a nice material.

[maru]

Corona 1.5 has a built-in Instagram. This is straight from VFB again.

[TomG]

I know constructive criticism posts are preferred over simply saying "Awesome!" but I am going to simply say - awesome! :)

[romullus]

Add a few bubbles here and there and you can easily sell this as a photo from Yelowstone :]

[rozpustelnik]

Composition and detail-wise still closer to uncanny valey than photo-realism, but nice try Maru! :)

[Fritzlachatte]

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.

[maru]

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. ;)

[romullus]

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 :]

[maru]

Random stuff #23

[dubcat]

Reminds me of the DOTA 2 logo for whatever reason :P Cool stuff :)

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.

[maru]

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

[maru]

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. ;)

[Nejc Kilar]

Looking great Maru, the volumetrics really make it work :) I wanna guess the movie was Blade Runner, huh?! ;)

[karklinskarlis1993]

that fog looks marvelous.

i am trying to achieve same cloudiness. can you tell more about setting up this fog?

[maru]

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...

[karklinskarlis1993]

"... 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)

[maru]

As promised. Have fun!

How do you like my *´¯`*.¸¸.*´¯`* sραcε αgε sнα∂εя *´¯`*.¸¸.*´¯`* ?

[TomG]

Where's the like button :)

[romullus]

Post in on facebook, then you could like it ;]
@maru, any 3rd party plug-in involved, or it's just pure Corona power? :]

[Zray]

As promised. Have fun!

Thank you. It would be good if you can add the like or thanks button for website.

[maru]

@maru, any 3rd party plug-in involved, or it's just pure Corona power? :]

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.

[romullus]

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.

[zuliban]

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.

[romullus]

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.

[romullus]

This: http://www.imaging-resource.com/?ACT=44&fid=17&d=3663&f=onionring_vanwalree_onion_aspherical.jpg
There's a nice article about bokeh characteristics and the reasons behind one or another phenomena (onion rings explained in aspherical lens elements section): https://www.bhphotovideo.com/explora/photography/tips-and-solutions/understanding-bokeh

[zuliban]

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.

[romullus]

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.

[Fluss]

Lovely bokeh! Corona is getting better and better

[maru]

Finally :)

• Added randomization by mesh component (contiguous triangle group) to CoronaMultiMap and CoronaUvwRandomizer

[romullus]

Suddenly the tree became much more realistic, yay! :]

[pokoy]

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. :)

Didn't it!

[Alexandre Besson]

Unfortunately still not compatible with instancing engine of railclone.

[maru]

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.

[Beanzvision]

Loving the cave scene ;)

[maru]

Happy Easter to everyone! :)
