How is it crashing? Are you spawning it in and it immediately crashes or does it spawn in but when you try to get in it crashes?
Common errors to check:
- YTD size needs to be below 16mb. If not, split it [How-to] Split Vehicle YTD Files to Avoid 16Mb Stream Limit (No Texture Compression)
- Vehiclelayout file is missing a “s” at the end to make it vehiclelayouts.meta (needs to match your fxmanifest)
