Export animation meshes once

[giuliojiang]

I use Blender and Luxrender 0.8
How can I make Blender export all the frames of an animation so that the PLY files are exported once, and used by all the frames?
In my scene there are a lot of faces, and each frame takes more than 30 seconds. Is it possible to save time and disk space during export?

Thanks

Apparently you can trick LuxBlend into doing it by using the External PLY feature, but we don't have an actual option for what you want yet.

thank you very much.
This could be the idea for a new feature in the next build of luxblend

One thing i've done on Linux is the following:

Export just the first frame with PLY Export enabled. Then go to the exportdir/blendname/scenename directory and run the following command. It will create all the rest frames subdirs (let's say there are 300 frames) and symlink all the PLY files into frames subdirs, so LuxBlend won't try to export them again.

Code: Select all

for i in `seq -w 00002 00300` ; do mkdir $i ; for f in 00001/*.ply ; do ln -s ../$f $i/`echo $f | sed s/00001\//` ; done ; done


Now go back to Blender, enable Partial PLY Export and export the whole animation.

that's a good idea. But I don't think I will use it because I have to send the scenefiles to some people that help me rendering that use different operating systems (mostly windows)
Anyway, the 'external ply' should work great, my scene doesn't contain too many separated meshes (about 100 objects)
