[C4D] General Discussion / Re: Corona Multi-Pass

On the mask, I think the issue is that the original pixels were already blended with the white (the background) since they were blurred and had to "spill over" into the background.

Doesn't help avoid re-rendering here, but you can use a Velocity mask to add blur in post, which will then do that blending with the background in post rather than at render time. The 3ds Max tutorial for Velocity would cover how all that works (https://www.youtube.com/watch?v=6Hk2jhbQTuI) other than it's name is different in Max :)

In this case, since the mixing of colors is already done at render time, I think your curves are likely the only solution unfortunately. Someone will correct me if they can think of a better workflow! (I would try getting a solid mask for the car, so I can leave that untouched, and then adjust the remaining exposed "blurred bits" with curves and mixing modes while leaving the blurred car itself unaffected)

The Multi-Pass help documentation is at https://help.c4d.corona-renderer.com/support/solutions/articles/12000023596-what-multi-pass-channels-are-available- (along with lots more C4D help on those pages!)

Corona has its own Multipass dialog, open it from the Corona main menu, Multi-Pass. You can then enable (or disable) all passes at once with the top checkbox, or each pass individually as needed. You may find the "Render only masks (disable shading)" in the General settings tab under the Render Settings dialog to be of use too!

Well, it isn't rendering to each, just rendering once and copying the results to each :) I believe you can disable this copying of the image in the Preferences (the overall Preferences, not the Render Settings dialogs, you can use Corona menu -> Preferences to open this, or just C4D preferences, same thing). Since it's just a copying of an image, it is unlikely to have any noticeable impact on things (and the advantages of having the two in sync probably outweighs any small difference there may be).

And in your screen capture, "Full (multiple bounces)" in the GI mode is PT.

See https://help.c4d.corona-renderer.com/support/solutions/articles/12000023596-what-multi-pass-channels-are-available-

Shadows

Shows the shadows (energy subtracted from the image due to shadow ray occlusion). This is the complement to the beauty pass, showing white where there are black shadows. If this pass is linearly added to the beauty pass, it negates the visible shadows. Note that currently the shadows from environment lighting are always shown, resulting in a washed-out pass in typical interior renders.
"

So the more of that pass you add in to the beauty image (Linear Add in Photoshop), the less strong the shadows will be (this may be the opposite of what you expect the shadow pass to be). Also see the note about environment lighting though, as that could be relevant.

Here's a helpdesk page which could be relevant:

Let us know which (if any) of those steps helped, or if you continue to have a problem. Have you successfully installed an earlier build by the way?

[Max] Daily Builds / Re: Corona Renderer version 2 Daily Builds Changelog

« on: 2018-01-29, 15:55:49 »

We have updated the Material Library, primarily based on feedback regarding tiling. Here is the changelog:

CHANGES:
- Resized and fixed tiling of Wall, Concrete, Leather, Metal, Rubber, Stone, and Wood materials.
- CoronaTriplanar map is now used wherever it is possible.
- Fixed the scaling of CoronaTriplanar maps used in Fabrics and Leathers.
- All CoronaOutput maps in Basic SSS materials are now set to be "Affected by Corona VFB tone mapping" so that they render as expected when any tone mapping is used.

NOTES:
- Any scenes created with materials from the older library will continue to render as before; these changes will only be seen when dropping a material from the new library into the scene, so full compatibility is maintained with your existing scenes.
- To install the new Material Library, simply run the Corona Installer again (any version of 1.7, or any of the daily builds for version 2) - the new library will then download and install.
- Since the first release of our material library, the scaling of materials is set for scenes that use System Units of Millimeters. If you are using Millimeters as your system units, then all materials will appear correct. If you see some unexpected results (such as displacement being too strong or too weak, or absorption color being too dark), you will need to adjust those material properties manually. This is still an issue of our material library, and we will resolve this in the upcoming major update.

[Max] Bug Reporting / Re: v2 daily builds - offline rendering faster than DR

« on: 2018-01-29, 15:19:39 »

That would be the cause as far as I know - the pass limit is based on the passes that the local machine has, so I believe two things can happen
1) Local machine has 29 passes, does the 30th itself, and asks the nodes for their last updates, which will add more passes and take it over 30
2) Local machine has 29 passes, and a node says "Here! Have another 6 passes!" which takes it over the 30 (plus, it will then collect any additional passes from any other nodes)

From my thinking, this will be affected by how long a pass takes to render in combination with how often the nodes send updates (fast rendering passes with longer update times, then increased chance of nodes adding a greater number of passes over the limit; longer passes and faster updates from the nodes, more likely they will just add one or two extra passes)

[Max] Daily Builds / Re: rendering restarting when click STOP

« on: 2018-01-29, 15:00:29 »

Could you share
- The scene where this is happening for you (there's a private uploader at https://corona-renderer.com/upload )
- A video grab of what you are experiencing
- A screen grab of the Common parameters in the render setup (just to be sure :) )

Also, have you tried with the newer daily builds to see if this is still happening? Is it in every scene or just one particular one? Which version of Max are you using?

Thanks!

[Max] I need help! / Re: Strange behaviour in dr with backburner

« on: 2018-01-25, 18:35:03 »

Do you have more details about the problem? Is it the red color that is wrong, or is it the stripes in the render? The stripes could be caused by missing plugins or textures on the nodes.

Also, are you sure all nodes have the same (and latest) version of Corona, as well as the 3D software and plugins? Is this the beauty pass or some other pass? Are you using backburner to render to DR, so that DR is used in both cases (direct DR, and backburner DR)? Does this happen in all scenes, or just this one (including in a simple test scene)?

Thanks!

So even with an offline render (not IR), it looks ok in the VFB, and only gets corrupted on saving to an image file? Which file format are you saving to, if that is the case (and let me know if I misunderstand, and it looks corrupted in the VFB too after an offline render, and only looks normal in the VFB with IR).
