[C4D] Feature Requests / The curious case of the Hair material preview

« on: 2018-09-16, 07:20:30 »

I sometimes create my own mat. previews. (the files in C4D Folder/library/materialpreview/ )

For the hair-material, I wanted something like the Arnold preview. Lazy as I am, I just converted the file.
The original uses a spline object which I reconverted to hair, cause splines are not supported yet.

However, the preview is pretty slow with hair. The override to use the original scene doesn't do much, it seems to depend on the pass or time limit but renders way slower(~ 10x) than the file itself at the same resolution. Rotation is futile.
It works fine with polygonal geometry but a poly mesh would increase the file size too much, for my taste.
The colors are also a bit off.



Could we get an optimized preview scene for hair?

At file opening, HDRI shows in solid color... still not solved.

...

Can't confirm that on Win 10, R19

Btw, @iacdxb, at first I thought you'd eventually notice but after a year or so, it's not funny anymore.
You should check your self-description under your avatar.

No need to thank me or maybe yes, because I bet I'm not the only one who had noticed it.
If I remember correctly, Nostradamus and the Voynich manuscript left some prophetic hints about that.
Nevertheless, I don't think I'll be seeing the change until Monday when I should regain consciousness.

I think you should ask this in the general help section.

I'm not doing your homework but I will give you some tips:

-You can disable the opacity and diffuse channel, they're not relevant here.

-If something is too opaque, the opacity channel is the last resort, after you have generated the overall look to an acceptable degree.

-If you want nonrefractive window glass, use the "thin wall" option in the refraction settings.

-Volume settings don't make much sense if you have unclosed/one-sided geometry.

-Jet fuel can't melt steel beams.

-You should be able to achieve your goal by only using the refl. & refr. channels. Leave the refr. level at the standard 100%, you can tint the "inside" with a color and you won't need much. (usually below 50% saturation)

-The devil's greatest trick was to make women believe, that yoga pants are normal outdoor clothing.

-It wouldn't hurt to give the glass a little bit of thickness.

-Rodents make bad romantic partners.

I've just had a small look at the file and didn't add lights, so I can't tell you if you should enable caustics for that part.
It depends on the desired look. Try what looks best.

Good luck.

Ok, I hope I could help at least a little bit.

A lot of my comments boil down to hoping to one day have just one engine that I can use for all types of 3D imagery instead of having to switch around between multiple render engines for specific needs...

PAINT 3D! Just wait, it's time will come.
But honestly, I think if there'll ever be an all-in-one package, then it'll be Maya. Autodesk just needs to buy a few more companies.

Ok, one last thing.
Have you tried Ozone for C4D/Vue Xstream?

You can make very nice clouds in there. The image still has to be composed but it should work faster than Arnold.

A support for the native cloud tool(or full Phys. sky) would be great, together with the option of adding CRN materials to add high-frequency details.

You could also try Navie Effex. It's for free now and you can load open VDBs and use them with AR.

Well, that's all about clouds and C4D.

edit: I just read that Furryball for Max, Maya, and C4D is for free now. Since Furryball supports pretty much all of the Arnold shaders, you could try and render the clouds with that.


edit2: one more critique. ;-)
What time of day is shown in your image? Clean clouds, especially in the morning have a well visible pink tint.

I often look at the sky, so the reverse engineered UFOs from the USAF that were shot down in Antarctica can't catch me.
Bob Lazar is still working for the government, he's lying to us!

Well, ok. I see no other way than compositing the image from different renderers. After all, they do it in movies too.
Baking doesn't make sense if you need a procedural 3D noise.

What I would recommend is to try Houdini. There you can create such things with ease using a non-destructive workflow. It has many presets, free stuff to download and almost everything has OpenCL support. It actually could make most C4D plugins obsolete. Terrain with erosion, vegetation, vdb modeling, fluids, liquids etc. etc.
The built-in Mantra & Renderman engines are quite fast drawing the media, but since you have Redshift, you could install it without any additional price iirc. You'll have more than enough noises for clouds ;-)

The Basic Non-Commercial version is for free,
the other two types depending on how much you make per year, but still, they're within a very reasonable price range.


PS: about your image, forgive me if I'm bothering, it's just one of my pet peeves... Large-scale scenes.
You should add a subtle volume to the scene to fake Rayleigh-Scatter. Also, a second flat, soft cloud layer wouldn't be wrong if it's not overdone. There you wouldn't need fancy scattering.
I also think that a small amount of a multiplied noise layer for the terrain, but also the water, to create a bit more variation could do wonders.

@Shawn

You could also use C4D's 3D cloud modeling tool (physical sky).
I doubt that there'll be much visible difference to the Arnold Volume. 3D noises work here too. Worst case would just need a little bit of post.

Arnold is still a great renderer, but unfortunately, it's designed to handle heavy TB sized scenes and therefore, a monster of a "computer" would be the best for that.
Arnold machine:


However, I'd say that if you need a biased renderer, go with Redshift. It has the familiar Arnold workflow and the speed is insane. My test scenes were easily 20x faster in Redshift, even though I used more bounces, a higher shading rate, and a much higher resolution. (BFBF on a GTX 1080)

For unbiased stuff with many bounces, you can still use Corona.

I guess it might be possible to run a supersampled approximation scene in the background, but then again, it's too much hassle just for that.

What about an optional info channel of the rendering which shows pixel variance per material(/id) with a drastically reduced bounce number as a blue-red gradient?

What about memory-display instead of MS? Same problem?

[C4D] Feature Requests / Re: Material Node Graph Performance Profiler(toggle)

« on: 2018-08-23, 14:45:03 »

ok, compromise. just show the time for the material.
as there are always multiple ways to create materials with the same look, it would be neat to see which way is more efficient.

I'd even be happy if it showed me a 1-5 star rating for the currently connected node graph. the values aren't that important, only the difference.
Since you can have the timings shown in the xpresso nodes, I assumed that it wouldn't be an impossible task.

A toggle to show the computation time of the nodes.
It'd be nice to have something like that:

Yes, please share it.

After my involvement in Project Blue Beam, the CIAMossad is making my life hard. The so-called holograms are actually real people who were phase shifted like LaForge and Ensign Ro in one of the episodes of Star Trek - TNG where the Romulans tried out some new technology to move their ships through matter, similar to Project Pegasus in a later Episode where the Federation tried to replicate a cloaking device and gotten that as a result.
Riker was involved in that too, but this time he was on Picard's side.
The Illuminati Lamp People used one of Elon Musks Mental-RayNvidia's Jensen Huang's I-Ray satellites to wipe the memory of NOTHING SPECIAL.
But I shaved my head, so the Melanin in the hair cannot function as an antenna amplifier. (I think that feature is missing in the hair shader)
However, the CIA NWO spooksfriendly agents for information retrieval also INVITED me out TO A NICE CAFÉ and I am VERY PLEASED.
Anyway, since I'm bald now, the Satanists Jehova's witnesses switched to spraying Chemtrails over my house or general area, not sure. The airport is not that far away and I see lots of planes. I fear that they're going to use the planes to drop needles filled with Vaccines to give me Autism and thus forcing me to use SketchUp PRO.
I also suspect that some of the dogs in the neighborhood are watching me. I've sent a bag of fecal matter to a laboratory to find out if the dogs were part of a Dog MK Ultra programschool, which one can find out by measuring the sodium levels.
However, I dunno, so I lay out poisoned sausages on the streetcandy. Where are the PETA animal death campsis a Volvo when you need one?

Better safe than sorry my mother always says.

But what do you mean by the "Redshift way"? Exposing all the parameters to the node system?

Redshift can take a lot of attributes from the native hair material and create something similar.
I wouldn't expose all of them. That'd be counterintuitive and not very Corona-like. Mainly diffuse and gloss types, but also things like the HSV randomization in the native hair shader to be somehow converted to melanin randomness.
If the native material worked properly, we might not need it.

Hi Shawn, I am guessing you mean the "C4D hair material" instead of "standard Corona material"?

I just tested all the various material on the hair object in Corona and everything works: Corona Material, Corona Hair Material and Cinema Material. The only thing that doesn't work is Cinema Hair Material, which we need to fix

At least the geometry can be controlled by the hair material.  However, I'd go the Redshift route concerning the material properties if someone wants to keep the c4d like hair.
