1's not so much that a library is needed - more that guidance is needed to make sure you're building materials the 'right' way.
Well put, davetwo. That’s exactly what I was trying to say with my long and winding post. ;-)
I do remember the “Paris Apt” scene, that’s a great example.

Of course no developer should be tied up in creating this, but I saw that the Corona Team has a freelancer job posting out, for a new 3ds Max Material Library Creator.
Maybe it’s possible to hire a talented c4d guy to create some “material scenes” under Render Legions supervision, so we don’t feel “left out”.

Hi all,
I never found material libraries particularly useful.
In my view, things like texture quality, final render size, personal taste, etc vary largely and materials from most libraries are never really a perfect fit. That said, I do understand the convince to “just drop something in” and move on, but that almost never looks any good.
Everything looks good on a shader ball!

I think it would be a lot more useful for everybody, if the Corona team posts a “material scene”. For example a interior/ exterior arch-viz scene with high quality materials applied. This would give everyone a good starting point and the ability to dissect materials, understand how they are correctly applied, how the scene is lit and quickly experiment with variations. A scene like this could grow over time when new shaders etc become available.
To give an example, to this day I’m not really happy with the look of my stainless steel kitchen appliances. Of course I can make a stainless steel material or get one from a lib, but when applied, it lacks realism. Missing variation in anisotropy, subtle fingerprints, dents, etc. If I had a scene where I can see how a pro builds/stacks materials and I can see the rendered results, that would help me a lot more than 50 “different” metals from a lib.

This could even be a forum feature, if a user believes he/she can improve the scene, to upload their variation.
Of course not everybody here is in arch-viz, but the same principle applies.   

Maybe I missed the point and this thread is not about improving your skills…

It's been a while... Any updates on TR nodes disconnect issue? Any fix in sight?

Hey beanz,
did you see my steam mesh? No edges to chamfer…
It’s what Tom said, the problem is, it’s only calculated on the surface.
The proximal shader also didn’t do the trick. I just brushed in the fade in PS.

Any plans to give the volume mat a “inside mode”?

Thanks Tom and beanz,
will give that proximal shader another try.
With the gradient you still see a “hard” outline at the mesh edges. I tried round,  irregular shaped meshes and different gradients (circular etc) and also different mapping, nothing really worked.
That's why I was hoping, the volume mat could be 3D mapped inside the mesh.

Hi Tom,
thanks for the explanations. I already tried to wrap my head around the Proximal shader, but I can’t figure out how to use it in this context. Can you point me in the right direction?

“that at a certain distance from a certain object the Absorption color is pure white (which counts as zero absorption, that is, no effect).” 

How does the volume material get mapped inside the volume mesh? I thought I might be able to achieve the fading with a gradient to pure white, but that doesn’t seem to work.

Great exterior details. Love the muddy water around the house. It’s always so tempting to make things “pretty”, but then loose all realism.
I feel the grass etc in the first shot is too saturated for this kind of foggy morning light.
Anyways, well done!

Yes, please. I'll take one of these magic pillows that can melt into the sofa.

Really well done Vladimir! You put an amazing amount of detail into this scene.
Regarding the motion blur in the daylight scene, I believe there would only be a tiny amount of motion blur in the cars. At dusk the pedestrians would probably blur more. Maybe photograph similar light situations and see what that really looks like…
In the dusk shot, is that a teddy bear driving the car? If it is, love your sense of humor!

I’m trying to create the steam on top of a jacuzzi at night. The problem is I can’t get the volume material to fade out. You can see in the screenshots that the steam stops somewhat abruptly at the outline of the volume mesh. I tried a gradient yellowish fog to pure white and also a texture with a gradient to 100% transparency. The texture approach looked even worse.
Can the volume density only be controlled by the “absorption distance”? My distance is set to 40 cm, If my mesh is less than 40 cm the volume should be “clear” correct?
Does anybody have an idea what else I can try to fade out the “fog”, besides “painting it in” in PS ?

Thanks in advance.

Did you ever consider / try installing corona in dropbox and symlink back to the plugins folder?
I use this to sync my content browser and plugins that are installed in USER browser/ plugins folders.
I’m not sure if this could work with corona installed in the main app plugins folder.
I did try that before but it didn’t work right away. Might be just a permission issue. Didn’t have time for further testing.
The advantage would be to install once and auto sync to all machines.
Maybe the devs can let us know if that is possible.

It's working for me.
I'm on v.4 current daily, but I believe it worked in v.3."1" too.
See below.
Bottom layer is the long brushed bump, top layer is the random scratches. Top texture is only in the projector shader to scale it down.

Bug Reporting Cinema 4D / Re: Team render issues
« on: 2019-02-08, 17:32:44 »
I recently reported client disconnects with just 3 clients. At the time when TR server had the memory leak issue I only used 1 client and that also had frequent disconnects.
This happened in automatic and in manual mode. Can’t imagine that 1 client can cause network congestion, but who knows? 

Is increasing the interval and/or # of retries when frame sync fails a way to give that “keep alive car” a chance to sneak onto the highway?

As kizo mentioned, setting up a 10Gb network is a considerable expense, even for small networks.
Cheapest 8-port switch cost about $600, + NIC’s, cables, etc.
About $1k+ to network 4 machines, not knowing if that will really solve the problem.
I already spend a lot of money on RAM, trying to fight the TR memory leak. LOL.
I learned my lesson.

Since you know your customers best, maybe you can survey all your 10+ nodes customers (especially those that have nothing to report) about their TR experience and network implementation and pass along your findings?

Also, as Stefan (former Mr. VrayforC4D I believe) points out here TR is flawed and he advocates for a real DR solution like implemented for max.
Maybe you can pick his brain, since he must have a pretty good insight into the inner workings/ shortcomings of TR.

We love you Corona!

Another licensing question:
When does the license countdown clock start ticking? At the time of purchase or when I activate the license?
I bought a yearly license on day 1 (Jan. 7.) but did not activate it yet. Let’s say I want to buy another license now to get that sweet discount and activate that license next year. Is that possible?
I guess I’ll find out when I activate my license if I “lost’ a month.

FYI: My only reason to buy on day 1 was the rumor that Corona invites all “DAY 1” customers to Corona's 50th Anniversary Party in the Elon Musk Club on the CORONA Mars colony.
If that rumor is true, and I can’t think of a reason why it wouldn’t be true, please send invitations early, I need to practice some zero G dance moves.

Thanks, and looking forward

I don’t wanna beat a dead horse here, but I’m still getting random TR client disconnects that makes Team Render highly unreliable.
Not sure how much this is a C4D TR rather than a Corona issue.
I saw on the trello board that “Team render stability improvements” are planned for V.4
Will the “com error” be addressed that causes frame sync to fail?
Once I finish my current job, will install V.4 daily and check if stability has improved.

To recreate this error, almost any scene will do, just setting the render res high enough.
In my case rendering a 6k image will trigger client disconnects.

Some FYI”s
- Network: 1Gb LAN, Jumbo frames enabled in the entire chain.[/li][/list]
- Server/clients all macs
- Random clients at random times disconnects.
- CoronaTR manual settings:
 Tried many different combinations 10s-20s / 50MB, 75MB,100MB, 200MB all combinations had disconnects
- I have the 1WS/3nodes license - disconnects if I use 1 or all 3 nodes.
- Adding clients over time, to possibly not have them all send data at the same time, does not make a difference and shouldn't with just 3 nodes.

I noticed all TR consoles always say “rendering pass 2” no matter what actual pass gets rendered.
Could increasing the time between the 7 retries help?
