Maxwell for Cinema 4D
Version 2.6.11 Release Notes

Changes

• Cinema Luminance Brightness is now used for MXI Emitter Intensity.
• Added support for the (R13) Cinema Camera's "Focus Object" link.
• Maxwell Fire exports are now performed using display LOD (in R12+).
• If no default mxm is found during export, one is written automatically.
• Optimized export of instances, when object motion blur is not enabled.
• Re-wote Render Region, to circumvent Cinema viewport z-clipping issues.

Fixes

• Emitter power was being read and written incorrectly.
• Auto-translated emitter power was written incorrectly.
• Cinema Luminance was ignored unless another channel was enabled .
• Hair UVs were exported reversed (length UVs for root, and vice versa).
• The wrong UVW tag could be used in some circumstances.

Animated Emitters woohooo, big thanks, x (now we can make TV screens etc. just put an avi into the luminance slot of a C4D material, and use it directly, it will autoconvert) Intensity is controlled using luminance brightness and multiply mode for the texture channel. (well thats whats working here)

You may want to increase the sampling size for conversion, its in the cinema tab of the maxwell scene object, and also turn on interpolation.


You can even animate the intensity of a hdr-still, for twinkling lights, or flickering neon without using multilight, or faking an explosion via hdr-bloom. etc.. etc...

Can I make a request here; C4D can use HDR image sequences for animated skies etc. but currently the plug does not pick this up, screenshot attached;

Hi JD

thanks for the new plugin and the lumiinance support.

in this new version I still find some issue regarding units. The z-buffer in the Scene object is set up in meters (not cinema units whatever they may be). But in the maxwell camera tag the z-clip planes seem to follow the units of the document.

See example scene:
http://www.william-associates.com/tmp/o ... issues.c4d

Cheers
Rogurt

[JDHill]

That is correct: while Z-Clip is figured relative to the camera (as it should be, since a camera may be rendered from any number of Scene Objects, each using different Export Units), Z-Buffer is specified absolutely, as it is elsewhere in Maxwell. Are you requesting that it be made to work differently (Z-Buffer being made to work in terms of Scene Object Export Units, I would assume)?

Eric: can you send me a simple example of a scene set up for this? The plugin is just asking the Cinema shader to render its HDR to disk for Maxwell at each frame, so it should work the same as it does for any other animated shader. I can animate a shader to use different HDRs in different frames here, anyway, so I must be doing it differently than you are.

[Rogurt]

It does not have to be that way. But if different units are used within the plugin there has to be some big hint within the plug in manual. I had a hard time figuring what´s wrong with my scene...

[JDHill]

Ah, I see -- I thought I had labeled this directly in the Z-Buffer UI (like in Maxwell & Studio), but that's not the case. It will be in the next build.

[Rogurt]

courteous as always

[eric nixon]

I could send you a scene, but i cant include a gig's worth of animated hdr sky. My test was really basic, only using the luminance channel in a c4d material. I loaded the first hdr into the slot and specified a range in the animation tab, thats all. I tried every combo of options in the animation tab, in c4d you get an animation but in maxwell just the first frame.

How do you achieve it? I'm using R12

[JDHill]

Okay, I see what you mean (I had literally keyframed a different hdr path in the shader, which works fine), now -- I'll see what I can do.

[jwiede]

I'm getting a 100% reliable crash on launch with 2.6.11 C4D R13 plugin & Mac64 C4D Studio R13(.058). After review multiple crashreport dumps, the crash reliably occurs at the same address & exception:

SIGSEGV @ Maxwell for Cinema 4D.dylib:CbaseExtension::internalCreation() + 4).

NOTE: Because of message length limit, I needed to edit crashreport, full one is available if needed but given nature of the crash and reliability of it occurring at that same point each time, I'm guessing what I've provided ought to be enough.

What this means is that the .mxx files found in your Maxwell /extensions directory are not version 2.6.10. So most likely, you just need to install Maxwell Render 2.6.10.

[jwiede]

Thanks, I could have sworn I'd already installed it, but regardless re-installing it did fix the crash.

[JDHill]

For what it's worth, I often have trouble with Finder "fixing" file associations and such -- I will trash the Maxwell folder and install a new version, only to have Finder try and open MXS files using the trashed binaries. So, when the plugin queries launch services in order to find Maxwell, it is actually given a path leading to a directory in the trash. Or, when opening an MXS via Finder, it will run Studio.app from the trash, which will crash, because it is unable to find its libs; ostensibly, some files are being redirected, while others are not. I have even, once or twice, found OSX keeping an old image resident in memory, even when the trash has been emptied, and its binary no longer exists on the system. So if there is any question, the only completely foolproof method I know of is to trash the app, empty the trash, reboot, and then install.
