Security

The security vulnerability is now fixed.

Known issues

• If you launch Pixyz Studio for display on a secondary monitor, the Viewer appears white and the scene is not displayed. This issue is caused by a conflict between nVidia GPUs and another software. Check this page for a work-around.
• Animations that are exported to USD formats (.usda, .usdc, and .usdz files) may not behave properly.
