[Bug] Failed to display list of Asset Reference at Inspector

Unity Engine

When you try to a Serializable class and make it as array, it failed to display properly but no problem when it’s not array.

Array

Not array

Currently only make AssetReference as array is working.

Hey!

Yeah, this is unfortunately a known issue. :confused: We’re going to try to get a fix in for this by our 1.0 release though.

When I can get the fix? I really hope I can get the fix very soon before 1.0 release.

@optimise While we wait for an actual release of this fix, we have posted some workarounds that make this work without problems. You can see them here AssetReferenceDrawer does not dirty the SerialziedProperty
