General CG Discussion / Re: 3DS MAX 1017: new UI (new icons, again?!) and new "ART" renderer engine...
« on: 2016-03-30, 01:00:02 »
The Noise-filter in the render dialogue looks interesting - I would like to try it on animation and see what it does. _ I did some previews of a file I am currently working on - did 1 minute low-sample render and the noise-filter did a good job cleaning it up.

I know we are getting a noise filter for corona in the up-coming version. I downloaded the latest nightly build but not yet in. Can't wait to see what your filter does.

Personally I am again disappointed by this release - there are new features but in my view not enough for a year's work and the cost. I would love to see them adding more modelling, sculpting (as much as Maya at least) etc..

One plus is my test-file saved so much faster. My files sometimes starts to get slow when saving (without adding significant data) and I then have to merge back in to new file.

Yes after effects use premultiplied or straight mode - but it still causes issues especially if there is heavy motion-blur or depth-of filed causing larger transparent edges. The problem is less visible if everything is in focus.

In this case doing motion-blur and dof in post will help

But the ideal is to have the edge-pixels colored with colors as close as possible to the backplate, which means the area-render around the selected object.

[Max] I need help! / Corona Render Selected on black cause wrong edge anti-aliasing
« on: 2015-11-19, 02:18:05 »
Please see the attached images

1. CoronaRender_Ideal_As-it-should-be.jpg: Explains using the Max Render Selected with Auto Region option: This is in my case is the ideal since the edges are Anti-Aliased with the correct background and overlapping objects. Good for compositing. It does not work for animated objects or camera movements since the region is locked in place on a network render and do not follow the selected object. The render also takes longer since other objects not selected that fall within the region are also rendered.

2. CoronaRenderSelectedWeakness.jpg: This image show a blow-up of the edge pixels with unwanted effect of having over-dark edge anti-aliasing

Maybe I am just missing something

[Max] I need help! / The solution for Corona Render selected for network render

The solution for Corona Render selected for network render: please see attached image

answers on replys:
No I did not see an error message

Yes I can understand/guess/deduct that the problem was the nodes did not know what has been selected in the viewport where the render originates from, except if the function was programmed to automatically include the ID of the selected in the render instructions send to the server. This should be documented somewhere (I think default max/scanline/mental-ray behavior allows this, that is why I used this approach first).

It did work using the selected ID feature. But I had to debug the problem by going to the dialogue and looking for additional features, searching on this forum and do several test to see if my solution now works before committing a job.

Great feature by the way, It cut down several sequences of 200 frames down from 10 minutes to just under a minute each.

I wish there was more explanatory help files where I can look up a feature I want to use (e.g. render selected) and the see an in-depth documentation of the feature-set instead of looking for answers in videos and guessing what the software developer's intend and target functionality was by reverse engineering the capabilities through trial and error.

I am not unhappy with Corona - this is a problem with most of the software I have worked with over the last 21 years. You most often need a 3rd party to come out with the Ultimate In-depth guide where functionality properties are explained and tested.

Also why I put this post up, because I could not find the answer and after 7 trial renders to the network trying different combinations I found the answer was to select the object manually again through the include/exclude dialogue.

Hopefully the next person will get to this post after one failure.

Thanks guys

I had some issues with using Render selected with Backburner/network render

I first tried using max standard "render selected" with "auto-region" selected - it worked for a couple of renders for a while and then suddenly all my renders defaulted to one specific region render

Then I watched the video on the feature again (
) and searched for more info and found there is a option in the Render dialogue under
Render Dialogue -> Scene Tab -> General Settings -> Render Selected:  Viewport selected
This worked locally but failed on network render, all frames came out blank

I then used the Include/exclude list option
This seems to be working now

"...but RenderMan's new denoising technology, originally developed at Disney,..."

does claim the Dysney Research Noise Filter algorithm is used - although I do not know to what extend. It might be a simplified subset.

Renderman also only use the "noise-filter" part of the total technology developed by Dysney Research in Zurich which also includes:
I think there will be some cases where this could be useful - like a controlled camera move in a architectural rendering or some of the supporting background fx.

Some of this functionality might fall apart in a more dynamic scenes with complex textures and fast articulate movements like character animation.

There is a huge difference between a purely post denoiser algorithm and one that uses "deep-sceen data" like z-depth, motion vectors and object-ids integrated into the rendering process.

As 4K is going to be the standard in the near future it makes sense. Our processors power is growing and make render faster (who tried to render with maxwell in 2006???), the quality and size of output also grows exponentially. There is also only so much detail the human eye needs to perceive quality.

[Max] Resolved Feature Requests / Denoiser pass Like Disney Research paper and implemented in Renderman
« on: 2015-07-09, 04:07:09 »
This can greatly reduce render times and maybe even create better previews. I am going to try it out in the non-commercial version of Renderman - since I am skeptical on how well it works in animation - but then it is not simply denoising - the algorithm uses motion vector data in it's calculation

Progressive Rendering in Network rendering like Maxwell
(http://support.nextlimit.com/display/maxwelldocs/Progressive+Rendering+Workflow)



Maxwell can be configured to allow the render servers to render a complete sequence at (n) passes -
For example (6,12,24)

The whole sequence will finish to render each file at 6 passes (at a low Sampling Level) and move to the next frame. When the whole sequence is complete it will then RESUME the render from 6 to 12 (does not need to re-render the already 6 passes) and save each, finally it will render the passes from 12 -24

In this way you can already use the sequence in compositing at a lower quality while the higher quality is in progress

[Max] Resolved Bugs / Corona_1.01 DLL failed to initialize on Max startup
« on: 2015-06-18, 00:43:52 »
CoronaUtils2015.dlt
Corona2015.dlr
failed to initialize
The specified procedure could not be found

It is because I manually copied Corona 2015 into 2016 previously and the installer could not clean it up - manually removing the 2 2015 dll files works

[Max] General Discussion / Re: Problem with Shadow Catcher for objects inside a "building"
« on: 2015-06-15, 01:18:24 »
Nope it is to simplistic an approach - what will work is if I render the interior as an environment map using the corona camera modifier's "spherical" lens-distortion setting - see the attached image

I then do not have to re-render the whole scene but just the animated small items and composite them on top of the static background

I forgot a bit about this workflow and glad Corona might be able to support it...

I included max 2015 scene in the previous post as an attachment - I think this is a limitation of the corona shadow-catcher/matte material

saved as 2015

I want to animated various objects in the scene without the need to re-render the interior - the example interior is a simplification of my actual design, but it has the same problem

When the whole building is wrapped in a matte/shadow-catcher material the shadows from the sun are extremely sharp and dark

[Max] General Discussion / Problem with Shadow Catcher for objects inside a "building"
« on: 2015-06-12, 14:17:45 »
I am rendering a "back plate" of an interior which takes a long time to clean up. Then I need to composite new objects inside the building. The obvious workflow is to render the new objects in a new scene with a matte/shadow-catcher material so as not to re-render the background again...

I have a problem with the render - the walls of the building with a Corona shadow-catch material does not block the sun-light the same way as when a regular material is applied to the "building" - see the picture

see the attached coronaMatte.jpg file

and the Max2016 file in the testMatte.zip archive
