[Addon] Corona Render Exporter v1.9.2

[3Djun]

It seems that node system is not yet supported or integrated with the new xml format. I get an error of a mal formed material matLib xml. - just read at the top post, material node is not yet supported.

But just for the sake of running render_corona_1.9.4_DEV.zip, definitely it works, but when I tried 77mb .blend file with hi-poly counts, strange thing happened, the GI computation is endless…

But all the scene files has been exported properly, when you render it using command line via the new xml format standalone corona, it works without delay.

Update: The exporter is not being actively developed while I am busy with projects. Development should pick back up at a later date.

Corona Renderer is a new renderer developed by Ondra Karlik. It’s available as a 3DS Max plugin or as a standalone renderer. While the standalone renderer doesn’t support as many features as the Max plugin, it’s still very fast, very powerful, and can produce very high quality images using a number of different biased and unbiased rendering algorithms.

You can download Corona Standalone binaries here.

Download the Blender exporter on bitbucket: https://bitbucket.org/ohsnapitsjoel/render_corona

https://vimeo.com/81228121

Standalone features (and exporter features) include:

• Diffuse, specular color, translucency, opacity, reflection, anisotropy / anisotropy rotation, refraction, normal, and emission image textures
• Instances / dupligroups / object and group particle systems
• Hair particle systems export as renderable geometry
• Mesh lights
• Physically correct sun and sky (Hosek-Wilkie sky model)
• Environment texture mapping (latlong maps only)
• Physically correct depth of field
• Unbiased/consistent rendering with path tracing, bidirectional path tracing
• Biased rendering with HD Cache
• Progressive and bucket rendering modes
• Blender material conversion to Corona material
• Render passes
• Orthographic camera
• Portal materials
• Normal mapping
• Material anisotropy
• Binary .obj export
• Per-material ‘rounded corners’ rendering
• Node system including mix / fresnel / ao / ray switch shaders / texture node / offset & scaling node
• Camera, object, and deformation motion blur
• Cython compiled mesh export to reduce export times (by more than 50% compared to regular Python export)

To install and use:

• Download the exporter from bitbucket, from the “Downloads” section
• Extract the exporter and place it in your /scripts/addons directory.
• Enable the exporter in Blender’s User Preferences > Render category.
• In the Corona Render user preferences, set the path to the Corona Standalone directory containing Corona.exe
• Select Corona as the renderer from the render engine dropdown.
• Set the export path.
• Render. Large scenes may take a while to export and load in Corona, so be patient.

Exporter To do list:

• Camera shift

Warnings:

• Only UV-mapped image textures of formats PNG, EXR, BMP, JPEG, TGA, TIFF, GIF are supported. Other projections and texture types are not supported.
• Some non-manifold and loose geometry (vertices, edges) will break rendering. Geometry should to be clean. Check the console for errors if rendering fails; Corona will report which .obj files are giving it trouble.

Thanks to Franz Beaune and Esteban Tovagliari for the original Appleseed export code and their continued help with that, much of which was used for this exporter.

Yep, it looks like those have been removed. I don’t host them myself. It’s my understanding that Corona Standalone is currently undergoing development, and I’m sure it’s in a state of flux and probably changing locations.

I tried tweaking the color map settings in the corona virtual frame buffer but I noticed each time I re-render the settings go back to default. Tried tweaking in the post processing tab in the render options in Blender. Those don’t update in the corona render window as well. Has this been disabled too?

It sucks that he is not working on it anymore, this could have been really good renderer for Blender.
It does not work on 2.77, hope he will updates.

Yeah, 2.77 uses Python 3.5; the addon was compiled with Python 3.4, so it’s not compatible as-is.

For the sake of total transparency - I won’t be continuing development on this any further. On a positive note, the code is still open source; anyone who wants to is welcome to fork it and continue development. Life, marriage, kids, work… there are only so many hours in the day for all these things, unfortunately.

[Saif]

Thanks for your work on it. it’s true life is important.
it still works on 2.66 perfectly fine, the only thing bugging me is the hair system it takes very long time to export it like for example if I want to make a rug, other than that it’s great.

Actually we have to say BIG THANK You for Your great work for our blender community. Your 1.9.2 exporter has changed live a many blender users. Corona is very good render engine. Thank You for giving us a source code - maybe someone will take a challange to prepare 2.77 version.
One more time - Thank You.
Greetings

What he(/she?) said! Thank you

[esimacio]

so very pity that Blender no longer works with Corona. It was a very promising renderer for Blender.

[Oyster]

corona should employ ohsnapitsjoel, just like vray employed bdancer

[Remade]

please post links to working versions of blender,exporter,corona.thanks

[burnin]

Amazing work is done by blanchg and continues here: Corona Blender Bridge

You are welcome to join Blender section on Corona Forums
and possibly support development

based on the great work from ohsnapitsjoel

Note: Chocofur scene renders again

- source on Corona Forums -

Thank you!

Is there are links on Corona Standalone version for Legacy_CPU?

[bnzs]

Just wondering is there technical possibility in future have progressive rendering in viewport like in cycles? because on big scenes export take very long time on same scene in cycles - few seconds…

[raiden1983 (Cgflux Studio - Piotr Lindner)]

Hi.I have a problem i download corona and addon for blender but i can’t active adon. Message tell me that tere is error missing DLL import/export. I have Blender 2.78. Mayby can tell me step by step how to do this. Or mayby someone has folder with workin corona and can upload it?

[burnin]

@bnzs

1. Standalone Legacy version is available within Max version (needs license tho & i think it was also mentioned is gonna be dropped)
2. IIRC, no preview rendering unless integrated in Corona VFB

@raiden1983
Which .dll is in question?
Have you installed “vc_redist.2015.update2x64.exe” which is included?

[raiden1983 (Cgflux Studio - Piotr Lindner)]

Yes i install vc_redist.2015.update2x64.exe but in error message ther is only that DLL is missing but nothing else.

[burnin]

64 bit system? Which Windows? OS & drivers updated? Installed as administrator? Possibility of AntiVirus or Windows blocking? You got full rights (read/write)? Restarted the machine? Which CPU?

Sorry, but with such a general description… am out of ideas. :rolleyes:
