Revit 2025.3 materials not syncing to D5 3.1

Workflow
1

D5 Render Version: 3.1.0.0746
Revit Version: 2025.3
D5 Sync for Revit Version: 0.5.0.0003

Issue Description:
Materials with textures do not transfer to D5 Render via either D5 Sync or Export (.d5a), despite the textures working correctly in Revit itself (visible in Realistic/Rendered view, no broken links in the Material Browser).

What I’ve already checked/tried:

  • Textures are stored in a local folder (not on a network drive or cloud-synced folder like OneDrive/Google Drive)
  • The folder is added under Options > Rendering > Additional Render Appearance Paths
  • No subfolders in the texture path (all texture files sit flat in one folder)
  • Materials show correctly textured in Revit’s own Realistic view
  • Im unable to change Windows Long Path names to not enabled (work pc)
  • Tested both D5 Sync (live link) and manual Export — same result in both

Happy to share a minimal reproducible Revit file (single object + one material) if that helps troubleshoot.

Hi @jst

Were you able to make this work with version 3.0.1?

We’ve tested Revit 2024 and 2025 with the latest plug-in version, and the textures appear normally on our end.

Additionally, a forum user previously experienced the same issue with 3.0.1 and resolved it by using PyRevit or by simply disabling Long Path Names in Windows settings.

If the issue persists, please send us the following:
