Some element meshes are not appearing in Power BI

When I connect the Tracer 3D Power BI visual to mesh fields, only some geometry is visualized with a warning icon.

The Tracer visuals render geometry using gLTF text strings stored in database records. Power BI’s report environment loads text strings up to 32,766 characters. It is very possible for a gLTF text string to exceed this and Power BI will silently truncate these strings. Here is a possible workaround to rendering large meshes

  • My mesh strings are exceeding Power BI’s character limit when loading data into the Report.
  • Go into the “Transform Data” environment in Power BI.
  • Choose your mesh column and choose “Split column” > “By number of characters”
  • Enter in the value of 32,766 characters and choose to split “Repeatedly”
    • Repeatedly will produce as many columns as needed by the largest mesh in your columns… careful, some meshes may VERY large require many columns?
  • Save and load the data with split mesh columns into your report
  • Within the Power BI report environment, create a New Column in your data source
  • Use the CONCATENATE() formulate to merge your split mesh columns back together.

How can we help?
