Silo Release Notes

Silo 2.3 Known Issues
All Platforms:
  • FACT exchange between Electric Image Animation Software (EIAS) doesn't appear to work. We are looking into it, and are in contact with the EIAS folks.
  • OBJ export then loaded into Substance Painter causes Substance Painter to crash. There are reports that importing the Silo-made OBJs into another package first (like Roadkill) and then exporting again will produce OBJs that Substance Painter can read properly.
  • Empty meshes (deleting all polygons out of them) cannot be finally removed from the scene, even in the scene editor. A workaround is to select the empty object in the scene editor, create a polygon with the Polygon Tool, select it in object mode, and then delete it.
  • Meshes with non-standard topology, such as having three or more faces share the same edge, will cause subdivision to produce corrupted results. Boolean operations and other operations may also fail on such meshes. It is planned in the future to have a mesh cleaner operation that can help remove problematic pieces of geometry for situations like this.
Linux Only:
  • Some desktop environments, such as Gnome, bind the Alt key to move windows by default. You must go into the window or keyboard preferences of your desktop environment to use a different key (such as "super") instead, so that Silo's default use of Alt for camera movement will work.
Windows Only:
  • Old data from Silo 2.2 and before may reside in the "Silo Data" folder inside "My Documents". This old data may cause issues as the newer Silo will try to use it as-is. If you run into missing icons, key bindings, or other issues, please rename Silo Data to something else. Silo will recreate the folder with the new default Silo 2.3 data, and you will be able to set up your preferences after that from within Silo.
