Lights#

Lights are exported and converted to compatible USD Lights. When a USD file is opened, USD Lights are converted to Native 3ds Max Lights.

Note

  • Not all parameters are mapped, only what is compatible with USDlux is converted.

  • Intensity does not always convert accurately between 3ds Max and USD.

Here is the current list of support lights.
