I have 2 collections in a scene (collection, items) both with objects (meshes, camera, lights). How can I select all objecst of type mesh from items and delete them?
bpy.ops.object.select_all(action='SELECT')
bpy.ops.object.delete(use_global=False)
With that I can delete all from the scene but I want to limit it to delete all meshes from items. Probably I can if the collection name and type mesh but maybe there is a simpler way?
Don't think there is a simpler way (as you mentioned in the question).
Globally:
Then (optional):
Commented code:
import bpy
collection_name = "items"
# Get the collection from its name
collection = bpy.data.collections[collection_name]
# Will collect meshes from delete objects
meshes = set()
# Get objects in the collection if they are meshes
for obj in [o for o in collection.objects if o.type == 'MESH']:
# Store the internal mesh
meshes.add( obj.data )
# Delete the object
bpy.data.objects.remove( obj )
# Look at meshes that are orphean after objects removal
for mesh in [m for m in meshes if m.users == 0]:
# Delete the meshes
bpy.data.meshes.remove( mesh )
