Blendigo 2.2.11

This version can be considered a Release Candidate for Indigo 2.2 stable. Please report show-stopping bugs only.
Windows
http://indigorenderer.com/dist/exporter ... taller.exe
Linux
http://www.indigorenderer.com/dist/expo ... .11.tar.gz
OSX
http://www.indigorenderer.com/dist/expo ... 2.2.11.zip
Changes in this release:
* Reduce progress bar updates for large scenes.
* Changes to make assets (images) location work on Vista
* Fixed logic error on GUI launch failure console message.
* Remove python-UTF8 coding mark from _igmesh module. (causes BOM error).
* Added back backbody emission and emission gain/exponent.
* Added error handling to launchGui if indigo executable not found.
* Fix colour picker and specular reflectivity GUI issues.
* Tentative camera rotation motion blur fix. Some oddness at start+end of motion.
Once 2.2 stable is released, I will be working hard on bringing some new features (and some old missing ones) to Blendigo for the next major Indigo version. Some of these require major changes and require much testing, it is too early to make them part of the forthcoming 2.2 stable release.

Hi,
I wrote the Indigo 2.2.11 topic ( Post14 Dec 2009 06:28 ) ,"I can't see the emit mesh light power . "
This blendigo ( 2.2.11.) good ,the emit mesh work ( is the light power ) ,But I haven't SUN
( Sky layer is ) .

the "XM" export meshes button doesn't seem to work here on OSX.
unclicked and it still exports the meshes every time.
and I think I see why I am still not getting the auto-launch to work on my system. it doesn't like spaces in the names of some of my folders - for example, my folder "Applications/3D content/" is giving an error like: "Applications/3D", "content/" could not be found. I will rename my folders, but is there a way for this to work regardless of the spaces?
edit:
yeah, actually, changing my folder names is causing too many problems for my scenes. I will live without auto-launching indigo for now

Thanks for the response, I will check the path quoting code.

Hi
The emitters seem not to have the same power (actually, I don't see the tag for the power settings in the .igs at all). For example, left emitter is RGB, R1 G1 B1, 1500lum, Gain 1; right is Blackbody, 1500lum, 5000K, Gain 1:

The setting in Blendigo was 1500 lumens, but for 15000 lumens the code looks the same.
The same strange thing happens to the Blackbody emitters just with different temperatures (3000K, 6000K), but the same power, for example:

I too noticed that blackbody power changes with temperature, and that power is somehow scaled differently when using blackbody vs. RGB.
I don't really think this is directly a Blendigo issue - perhaps Nick can comment on this ?
As for the actual power value not being exported, I will look into that.

Here are the tests with the exactly same conditions, but exported from Blendigo 2.2.1 (camera tonemapping):

OK, I found the problem. Exporting the emitter power will be fixed in the next release. Indeed now both RGB and blackbody (5000K) of equal power appear equal brightness in the render.

That's great!
May I ask, will the emittance, luminance and intensity options be back in Blendigo emission scale settings, or only flux will stay?

I think 2.2 stable will have only the Power (luminous flux) parameter.
The other 'emission measures' (flux/intensity/emittance/luminance) will re-appear in the 2.3 series.
