> [!abstract] Summary > Common **Deadline errors** seen on the OSMIUM farm and their fixes — light tree warnings (point/spot lights), offline workers, missing output frames, "Asset Not Found", jobs stuck in queued status. --- # Light Tree — Point / Line / Spot Lights > The light tree is an acceleration structure to help with rendering scenes with large numbers of lights. If the lights are point lights or have shaping controls enabled such as spotlight, then the acceleration structure won't include them and they will be evaluated sequentially without any intelligent light picking from the tree. --- # Workers Showing as "Offline" **Causes:** - Network connectivity lost. - Deadline Launcher crashed. - Hard drive full. - License server unreachable. **Solution:** 1. Verify network connectivity: `ping worker_ip`. 2. Restart **Launcher** service on the worker. 3. Check worker disk space. 4. Verify license server is reachable. 5. Check worker logs: **Tools → Job Reports → Select worker**. --- # Render Output is Missing Frames **Causes:** - Tasks failed without requeue. - Output directory permissions issue. - Disk full on output location. **Solution:** 1. Check job **error reports**. 2. Verify output directory is **writable from workers**. 3. Ensure output drive has sufficient space. 4. Check **path mapping** for the output directory. --- # Tasks Failing with "Asset Not Found" **Causes:** - Asset paths are local (`C:\`, `/home/`). - Network drive not mapped on workers. - Wrong path-mapping configuration. **Solution:** 1. Move all assets to the **network repository**. 2. Use UNC paths: `\\server\share\assets\`. 3. Update **path mapping** in Repository Options. 4. Resubmit job. --- # Job Stuck in "Queued" Status **Causes:** - No workers assigned to the job's pool. - Insufficient workers available for group / limits. - **Pulse** service not running. **Solution:** 1. Verify Pulse is running: **Tools → Pulse Info**. 2. Check pool assignment: right-click job → **Job Properties**. 3. Verify workers belong to the job's group. 4. Manually resume the job: right-click job → **Resume**. --- # 🔗 Related - [[../DEADLINE MOC|DEADLINE MOC]]. - [[DeadLine Basics By Loris Eck|Deadline Basics — Loris Eck]]. - [[Deadline For Alternatives Productions|Deadline for Alternatives Productions]]. - [[Render to Deadline without Prism|Render to Deadline without Prism]]. - [[Deadline script log analyser - Thomas Spony|Deadline Log Analyser]] — automated triage. - [[Reconfigure Deadline|Reconfigure Deadline]] — pool/group structure context.
