Properties

Properties

Property	Description
Settings
Entries	Entries are a list of meshes (soft) references descriptor and their associated shared properties. You really just need to set the Descriptor’ StaticMesh property for it to work.
Do Not Ignore Invalid Entries	Forces distribution of this collection to NOT skip over invalid entries. This can be useful to create ‘weighted’ spaces, and can be overriden on a per-node basis.

Advanced
Auto Rebuild Staging	Enabled by default. When enabled, any user-made modification to the asset collection will trigger a rebuilding of the staging data (saves you a click, in case your forget about it.)

Common properties

Common properties are properties shared amonst all asset collection’ entries

Property	Description
Sub Collection
Sub Collection	If `Is Sub Collection` is enabled, lets you pick an Asset Collection that will work like a list of alternative choices for this entry.
Is Sub Collection	Whether this entry is a sub-collection or not. Enabling this option will reveal the Asset Collection picker.

Settings
Weight	The weight of this entry, relative to the others in the list. Higher weights means higher chance of being picked, if the context is using weighted random selection.
Category	A category associated with this entry. Think of it as a unique tag.

An entry Weight is not only used for Weighted Random selection, but is also used to sort entries in certain cases; among which Indexed Weight (Ascending/Descending) distribution mode of the Asset Staging node.

Variations

Optionally, you may enter a few random ranges for staging nodes to use, should you want to.
This can come in handy if you want to have high-level, per-asset variations.

Positions	Additive
Offset Min	Minimum offset range.
Offset Max	Maximum offset range.
Absolute offset	Whether the offset should be applied in world space, or “local” to the point’ transform.

Rotation	Additive
Rotation Min	Minimum rotation offset range.
Rotation Max	Maximum rotation offset range.

Scale	Multiplicative
Scale Min	Minimum scale multiplier range.
Scale Max	Maximum scale multiplier range.
Uniform Scale	Whether the random scale multiplier should be applied per-component or uniformly (in which case it uses `X` for all components).

Note that variations are never applied by default by any nodes, and are considered an advanced tweak.
