[Max] General Discussion / Re: Gamma Correction Tone Mapping Operator Removed - Bring it back!

« Last post by fraine7 on Today at 19:47:39 »

Thanks for the reply TomG, I do understand that it was only introduced to fix/correct a technical issue, but now that we've seen and used it for artistic purposes it becomes hard to forget, and it does beg the question, why has it taken so long to be included?

Would it be possible to reintroduce the operator under a different name so as to avoid the colour management connection, something like 'midtone depth or midtone contrast'?

Seems a shame to leave such a useful and effective post-production tool on the shelf when all of the work has already been done by the developers.

[C4D] I need help! / Re: Copying and Pasting Objects messes up the materials. Help!

I always assumed Corona would merge materials base on name alone as each material can have drastically different contents. I haven't run into this situation, but if it's true then Corona needs to do a scan of each to determine that they are indeed exact duplicates. In addition to that, a warning box should pop up informing you that the materials with the same name are are actually different and then ask if you want to merge or keep both. Something like that.

[C4D] I need help! / Re: Instances with Decals. Problem

« Last post by BigAl3D on Today at 18:09:44 »

I had reported this same issue a long way back, and Benjamin showed me one step I was missing. I can't remember it now of course (the image was of Stonehenge made out of giant Christmas tree lights). I had some grunge decals that were not rendering on the instances. Benjamin showed one simple thing to make it work. Same as this, but now that I set up a test scene, it seems to work. I used the same C4D r20 as before.

Wait, I just remembered the solution. Wardy, make your Decal a Child of the mesh. That should do the trick. I just tested this and it still works for me even when not a child. Let us know either way.

[C4D] Daily Builds / Re: Chaos Corona 12 for Cinema 4D daily builds - Changelog

« Last post by Ales on Today at 17:41:31 »

Please check this article covering the risks of using daily builds: Daily Builds FAQ
Use daily builds at your own risk and always make backups of important projects before opening them with a daily build installed.

NOTE: This version installs new data used by PRG sky model that is currently incompatible with previous versions of Corona. This data is automatically upgraded/downgraded when running installer, however you might have problems if you use multiple versions of Corona at the same time (for example when keeping older Corona versions installed in separate installation of Cinema 4D). We are working on removing this limitation in the future daily builds.

Changes in Corona 12 for Cinema 4D (Daily Build) (https://drive.google.com/drive/folders/1kZij6EEuQ1y-raj9m83P_6sRQ3TSUXCM):

• Added:
• Added option to enable edge trimming for the whole Chaos Scatter (i.e. without modifying individual materials used on scattered objects)
• Added spline UI for additional control of Look At in Chaos Scatter
• Added option to select connected nodes (incoming and/or outgoing) for nodes in material node editor
• incoming nodes can be also selected by Alt + left click
• When new material/shader is added in material node editor, all newly added nodes are selected
• Added support for exporting several C4D shaders for rendering with Corona Standalone (Checkerboard, Normal direction, Fresnel, Gradient, Falloff, Fusion and Layer)
• Added accurate sampling mode for environment maps that is slower but delivers more accurate results, especially for large environment maps
• Added option to distinguish media based on their material (e.g. two intersecting objects with the same material will be now considered as a single volume)
• this is automatically active for new scenes
• Fixed:
• Fixed several issues in Chaos Scatter where instances would not generate for a long time
• This should hopefully resolve some of the reported issues where the scene would not load for extreme amount of time, please let us know if you can still reproduce it.
• Fixed issue where changing tone mapping after rendering finishes would reset color profile of image in Picture viewer
• Improved detection of low memory on macOS (showing RAM usage warning)
• Reduced UI freezing when using distribution shader in Chaos Scatter distributing over high amount of triangles
• Fixed maximum value for randomization options in Tile shader
• Changed:
• Legacy options in Development/Experimental section in render settings were organized into single section
• Extended range of solar elevations supported by the PRG sky model
• it can now render all solar elevations down to -12 degrees (previously only to -4.2 degrees)

[Max] I need help! / Re: Render multiples camera matching

« Last post by Frood on Today at 17:19:28 »

CoronaCamera environment overrides are in progress and this should be easy to do in future :)

This alone will not. In almost every camera matching scene, you additionally need at least one shadow catcher material using the current background image for matte objects. This cannot be covered by a camera environment override. Additionally, think of camera matched/tracked animation.

In the meantime, there may be different workarounds with 3ds Max Scene and State sets.

Either I have/had crashes (yes, with CoronaCamera parameter block queries in the call stack of the crashing thread) or had them stop working midst project doing weird stuff. Additionally rendering out multiple shots in one go is not possible without making things complicated. So I humbly returned to the workflow described above after each try :)


Good Luck

I think, we are talking about rendering the scene with corona and the particles separately in Redshift

It seems like you are getting the light transport issue. It is listed in our known bugs and limitations here: https://support.chaos.com/hc/en-us/articles/4528311915025-Known-bugs-and-limitations

here is a workaround solution for the issue: https://forum.corona-renderer.com/index.php?topic=32357.msg181607#msg181607

I hope this helps.

Gallery / Klein Office (Animation + Stills)

« Last post by viz.art on Today at 12:45:17 »

Hi guys!

I want to present you with a set of still images and an animation created for the project we took care of a while ago.
We were responsible for designing the coworking space and preparing a set of CGI and motion.
The main idea was to emphasize the existing ceilings and use their rhythm as a matrix for a couple of other finishings.
Our goal was to create a welcoming space with a dose of refreshing energy from greenery that would be helpful for creativity.

Hi, what version are you using? It's working here. Perhaps you can share your scene also?
