Subject: Use correct pickup item bboxes on clients
X-Git-Tag: xonotic-v0.8.6~93^2~1
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=2c5fb2544a77f2cf5fb786aca0d3e8b6e8aaf0cb;p=xonotic%2Fxonotic-data.pk3dir.git

Use correct pickup item bboxes on clients

CSQC items currently don't use the item registry so properties including
model and size must be networked.
