Camera Motion Bug

Blendigo 2.0.10/Indigo 2.0.12/ Windows
If Camera Motion is enabled then the camera position data:
<camera>
<pos>
isn't written to the .igs file and therefore you will always get only the first frame rendered no matter what frame you are on. Object Motion blur works fine but if Object and Camera are both enabled then again the position data is written.
So my cack handed workaround atm is to save a .igs without Camera Motion enabled and look at that for the camera pos data and copy it. Then save a new .igs with Camera Motion enabled - open this .igs and paste the earlier saved camera pos data.
This also only works if you want to render a single frame. A full animation sequence would be a lot of work using this method
There is probably a much easier way to do this but I'm no programmer - was a miracle I worked this much out!

Are you using the latest 2.2.1 build?. Cos I just updated to that and it seems to be working ok now. Weird
But hey as long as it works. Thanks for looking into it so quick.
However I may still have found a bug in either Indigo or Blendigo. If you just rotate a camera you should get camera motion blur but that doesn't seem to happen. If you introduce even a tiny bit of Loc movement it works.

Hi Smartden
Been doing some tests.
#1: I'm still getting just frame 1 rendered no matter what frame I'm on. If I turn off motion blur I get the frame I'm on rendered. Also if I export the entire sequence and then render any of the frames they are all frame 1.
I have uploaded
http://cid-dee301fc4ac2d000.skydrive.li ... Blur.blend a simple blender file that has an object move from right to left. It may just be my inexperience with Blender's animation system but I can't see what I am doing wrong. Either way would like a solution.
#2: A very small bug. If you have NO camera motion but select the Camera Motion button you get a python script error. Not a major thing but maybe do an error trap on the error to ignore it?
#3: spelling mistake in tooltip for 'Exposure' secunds=seconds.
