Delete unrenderable layers

[mcatg6k]

Anyone know a script that can delete all render layers in a file based on their non renderable status? Trying to speed up some otherwise very long and slow editing of scenes. Thanks in advance!

Just the layer? What good would that do, the data would still be intact. Or do you mean also the data associated with the layer? Anyway for the literal interpretation of your question its pretty simple just do use mostly the same code as you had previously:

for ($layer in stringArrayRemoveExact( {"defaultRenderLayer"}, `ls -type renderLayer`)){
   if (! getAttr($layer+".ri.rndr"))
       delete $layer;
}

As for deleting the resources associated with the layers that's a bit tricky as you need to check for what other layers items are in and maybe what other associations they do have. This can not be done quite as easily as it requires quite a bit of special cases to be handled properly.

PS; you may want o add a renderLayerCleanup at the end of the script

PPS: the reason you don't want to use age old threads is that the system will drop the tread out of visibility very quckly whereas your current tread has a much longer visibility.

Actually I can't give too many details about the project itself but we are using 30 or so characters and we have an inhouse script to change their translate depending on the render layer. The idea is to then comp those to get the whole crowd. However we use a template and depending on scenes some of the layers become obsolete (not showing on camera). So to make the scenes lighter etc we just delete those render layers (the characters are still in the scene obviously but not in that crowd position and its also why we cannot just playblast the scenes).

Deleting the layers manually takes lots of time because the render layers reload etc. However it doesn't take much time to make the layers unrenderable, so with a script that loops through the render layers and deletes those that have been checked unrenderable we can gain a lot of time. I hope this makes it clearer I will try your script and see how that works.

Thanks I adapted that to the way the scene is set up and it's working great
