[Unsupported] Blender plugin v1.xx - Code Tweet

[yoyoz]

Hi guys,

here's the 'Next-Gen' plugin. Please carefully read the Documentation before trying to install. It contains important information.

- It will not work with Blender 2.56a or too old svn builds. Please read the Documentation.
- It may destroy data and/or make your files unusable. Please check the Documentation.
- Before asking how it works, please have a look at the Documentation.
- Please do not report problems without properly documenting them (console logs, screenshots, steps to reproduce, etc...). Offenders will be flamed!

Roadmap:
- integrate "Mesh Preview Imager" in World panel. I need some info from RS for properly implementing that, but have no feedback yet.
- allow use of texture from texture panel instead of file name for the environement map
- network rendering (long term plan)

I hope you'll enjoy this plugin and that it'll make your life/workflow easier. Some options/features are clearly only usefull for animations and I hope you'll be able to share your experiences here. It'll be nice if some of you could make tutorials, as I understand not everything is obvious at first glance. In the meantime, there's a Documentation, in case you missed it

Happy blending and rendering,
Lionel

[2011-03-05] First 'public' release v1.09. Please do not spread this plugin everywhere - read 'FAIR DISTRIBUTION' statement in 1st page of the Documentation.

[2011-03-15] v1.09b : update to match blender API change for builds since March 15th. No other changes. Will still display 1.09.
[2011-03-16] v1.09c : fixes code following additional API changes. Will still display 1.09.
[2011-03-23] v1.09d : more API changes, new version. Will still display 1.09.

Hey,

Abstrax told me you are exporting to ocs ? Is this the case ?

This is a really bad idea for several reasons, ocs is very low level and changes constantly, your exporter will never be able yo be kept up to date as we don't release docs and specs for it.
Also, we are building a new xml io format specifically for this...

It will be much better to stick with our plugin development guidelines, to make sure all plugins work and will continue to work with newer versions...


Seriously, save yourself a lot of headaches and don't write ocs files, you will run into numerous problems, such as new features, nodes and pins missing, and many many other things...

Hi Radiance,

yes, and I know it's a bad idea but there's no alternate solution available yet

The risks writing directly into the ocs files are cleary stated in the documentation I provided this morning, with a clear disclaimer RS is not endorsing this approach. However, the way I proceed is pretty safe at the moment with ocs files for beta 2.43 and 2.44.

If your new xml I/O format can achieve same result, I'll be more than happy to switch to it. If you're ok for sharing some info off-the-record, let's discuss that directly. In the meantime, the fact is that you have no working official plugin available for any recent 2.5x version of Blender, including 2.56a, but I don't want to become an official plugin developper either. I've given Enrico the insurance he'll get all information needed from me to adapt my plugin(s) in order to quickly provide/adapt the official one. I guess this will happen when Blender 2.5 goes final.

I'll PM you to confirm my email address and also a couple of IM ids if you want to discuss more interactively.

Hi Lionel,

Your plugin is really great!!
I only have one problem: Octane Render is launched two times each time I launch the render.
Have you any idea about this problem?
Do you plan to add a panel for the Mesh Preview Imager?
Thanks.

Patrice

[yoyoz]

Hi Patrice,

I've never faced this behavior before. Does it happen all the time and can you send the console logs? (I'm not able to look at them now as I'm travelling for business but will do this WE).

I will add a panel for the Mesh Preview Imager if the new XML I/O file allows to pass its parameters to Octane. At the moment I've no informartion so I can't confirm.

Cheers,
Lionel

You can see that Octane Render is launched two times.

Regards.

[yoyoz]

Yep, I can see the render thread is started twice while the 'render' button only hit once.

That's pretty strange but I'm not even able to reproduce as Blender is broken at the moment: latest svn builds give me segmentation faults in various areas (not only when trying to export). At the moment I can just hope this problem is specific to the build you're using. The "Status set to Info" line shows that the exporter has exited from the render function and I see no reason it could be called again - except some new behavior of Blender I'm not able to test until they fix the seg fault issue.

In the meantine may be you can try with a different build of blender...

Cheers,
Lionel

[yoyoz]

Well, I should have looked at the available updates for blender before posting, as this morning's build has fixed the segmentation fault problem.
It sounds it was related to python as they're moving from 3.1 to 3.2, so may be that was the issue.

Please give a try with build 35474 or higher and let me know if this happens again. Please also check which version of python you're using - may it's builtin with the Windows package but I can't test.

Cheers,
Lionel
