Before you start

Make sure these basics are in place before following the workflow.

Users need to understand replacement risks and safer alternatives.

Confirm whether the vehicle is add-on or replace.

Back up the original resource.

Match replacement file names to the target model.

Keep replace resources isolated from add-on packs.

Test traffic spawning, tuning parts and textures before public rollout.

Keep copy-ready examples near the workflow.

stream/police.yft
stream/police_hi.yft
stream/police.ytd

Checklist of failure modes reported across forum threads and hosting knowledge bases.

Wrong file names
replacement YFT/YTD must match the target model name.
Traffic or missions spawn broken cars
another resource may be overriding the same model.
Missing _hi.yft
high-detail model is not included, so the car disappears at distance.
Tuning parts break
carvariations or carcols conflicts with the replacement.
