A racing game team edits 3D vehicle models. Two artists’ changes to one binary model cannot be usefully merged. Coordinating exclusive edits matters more here than parallel text branches.
How: work toward a solution
Set the model’s file type to binary+l. One artist opens it for editing; another open is refused. Submit the finished changelist, then the next artist syncs and edits.
One vehicle model has one editor until successful submission
Racing game · binary vehicle asset
One file. One open editor.

Configured exclusive-open file type
01 / Artist opens for edit
OPEN · can edit
02 / Second artist tries to open
REFUSED · wait
03 / submitFirst artist submits the changelist
04 / sync → editAfter success, next artist gets the new model
+l must be configured. p4 lock restricts submission, not opening. Failed submission needs recovery; locking can delay teammates.
What: the concept
Perforce P4, formerly Helix Core, manages versioned files through a server and workspaces. Exclusive opening requires +l configuration; p4 lock alone does not prevent another open. Locks can cause waits, and server operation and licensing need planning.
Compare asset characteristics before choosing a system. The example uses a binary model for which merging competing edits is impractical; configured exclusive access serializes work. Git and Mercurial favor distributed local history, while SVN can also use locks. P4 is not the only locking option: existing asset tools and team workflow decide the fit.
02Applications
The vehicle model is explicitly assigned binary+l. An artist opens it, edits and submits a changelist to the depot; the next artist syncs the submitted version. This models a central P4 workflow, not every available topology. A failed submission does not prove the next artist can proceed.
03Implementation & cautions
Review the typemap for selected asset types. Distinguish +l, which restricts opening, from p4 lock, which restricts submission. Name an owner for abandoned-lock recovery and repository backups. Recheck current licensing, user limits and hosting terms for the team’s actual workload; this article makes no free-tier or price promise.
