I think the idea is just brilliant.
Finally someone tried to make things work easier.... but still not enough for me.
Maybe I'm using it the wrong way or didn't install it the right way.
No matter how I try to use the script, it gives me back error messages.

It'd be nice to have a tiny txt file with installation and use instructions for those who like me are trying to take advantage from this usefull tricky script.

Thanks ;-)

For me making the sunData function global:
global proc float[] sunData
solved the problems. A cool one.

Getting the following errors when using script:

"// Error: Cannot find procedure "sunData". //
// Error: An execution error occured in the expression expression3. //
// Error: Cannot find procedure "sunData". //
// Error: An execution error occured in the expression expression3. //
// Error: Cannot find procedure "sunData". //
// Error: An execution error occured in the expression expression3. // "

Edit: Nevermind. Got it working. I added a line to the script and everything works fine.

Cheers.

where in the script to do add that line?

i get syntax errors, (would like some help)

Cool idea, and perhaps I have got this bit wrong, but it seems that the Time Zone attribute and the Local Hour attribute are not linked up to any other Time Zone than GMT London.
Because of this the user has to work out the Local Hour manually for any other Time Zone. It would be awesome if this calculation was done automagically.

Have to link Latitude and Longitude manually. Problem solved.

I've tried the newest script in Maya 2010 and everything works fine so far. I love the features and the way this works. It's really easy to change and animate the settings. Extremely useful for architectural visualizations.

Only thing that would be cool: an In-Maya conversion of the coordinates ;) Somehow I also think that the sun is too dark overall in the evening but I guess that's a problem of Mental Ray Sky+Sun.

This is exactly what I need, but i can't seem to install it correctly. I have maya 2010. Hey onkelandy... could explain how you installed it? I followed the original instructions, but it's not working. I do have vista by the way. Thanks.

By the way, the error i receive is :
# Error: NameError: name 'geoSun' is not defined.

I can't get this calculator to produce plausible results.

I am checking the results against the calculator in Geoscience Australia, sunposition.info, NOAA and my own calculator, and the results are wildly different.

Check out these calculators:

http://www.sunposition.info/sunposition/index.php
http://www.srrb.noaa.gov

Possibly my usage is incorrect, but I think I've read and understood all documentation.
I would definitely recommend checking the results produced by this calculator!

When i enter any value into the extra attributes. it doesn't change anything at all once render == swt ~
