[Bf-python] Bf-python Digest, Vol 130, Issue 2

[Jamie Murray]

Have a look at tile rendering add ons (this link is old and may not be
maintained however)

http://blenderscripting.blogspot.co.uk/2011/07/monster-tile-renderer-v03-blender.html

The easy part is selecting how to render your tiles, the trickier part is
automatically re-stitching them back together, however once you get the
numbers right it pretty much works all the time.

One approach I've taken (not using Blender) is to render each frame and
embed the co-ordinates into the name of the tile using the same script that
drives the rendering.

For example:

top left tile:
anim_seq_01_0.0-0.5_0.0-0.5.png

top right tile:
anim_seq_01_0.5-1.0_0.5-1.0.png

where 0.0 is first (in this case top/left) and 1.0 is last (bottom/right)

anim_seq_FRAMENUM_topleftcoord-toprightco-ord_bottomleft_coord-bottomright_cood.png

That way you can have all your tiles in a format that the tools to stitch
them back understand and if you have a failed tile you can simply re-render
that one and try again.

Cheers

J.Murray
