[Bf-committers] SVN commit: /data/svn/bf-blender [37537] branches/soc-2011-pepper: == Simple Title Cards for Sequencer ==

Mon Jun 20 16:15:22 CEST 2011

about workaround, I asked DingTo to change the max value of the Ortho Size
parameter in Blender.
So if you set the camera to Ortho and the Ortho size the same value as the
Resolution_x of your camera (render settings). 1 pixel on your screen
becomes 1 blender unit. which can be useful for this kind of stuff
(subtitles, ... ).
It was possible before, but the limit was up to 1000, which means at the
time you could only do that with SD footages. Now the limit is up to 4K.
(but it might need to be 10K actually since I believe it is the limit of
Resolution_x, just to keep it consistant)

cheers,

F
