I am starting to make the transition over to python however I find the docs confusing at best regarding certain commands. For example I want to query renderOpts however the python implementation doesn't seem to be working in which the same way Lscript does. I understand not a lot of highlevel access has been implemented yet, but I don't see how the current information can related to the values it should. For example:

@warnings

@version 2.7

@script generic

generic

{

info(Scene().renderopts[12]);

}

In the above code, my scene returns 0 since my SaveRGB is unchecked. However I now run the closest equivalent command in Python :

import lwsdk

lwsdk.LWSceneInfo().renderOpts

And now I receive a long integer, 270286855. So I see that the data is now stored into an integer rather than to an array. This is frustrating because I have no idea what to do with this number. If I check the SaveRGB and rerun the same command my value is 270288903 which I don't see how it relates to the first value. My main question is in this case, using this integer how do I extract the appropriate data out of it? I also dont know if I am even invoking the command properly, as I also tried to use the get property in various ways to no avail.

Any insights would be greatly appreciated.
