What's New and Improved in Lotta 2023.2

This release includes the following new and improved features:

• Apple Silicon Native Support​​

This release includes full compatibility with Apple’s M1 and M2 processors, enabling faster simulations. For further information, see the System Requirements.

• HDRI lights
  
  HDRI Light improvements include improved 3D orientation, standardizing the 3D display with other 3D tools, and tools for better control over the lighting of a scene. This version includes the “Link HDRI to camera​​” option that allows controlling an object’s shadow.  
  For more information, refer to Adjusting the 3D Window Environment.
  
  
• Parametric Lights

Included the ability to define custom Parametric Lights, to improve the overall look of the render output. You can add area, spot, directional, or point lights. Using Parametric Lights reduces dependency on HDRI, which requires more computing power for Unreal.

For more information, refer to Parametric Lights.

• • Support of Substance for fabrics, seams, artwork and trims
