QUESTION
Why does Lumion sometimes freeze, crash or stop responding when you start rendering?

ANSWER
That will occur if your scene is 'too complex' and your hardware isn't powerful enough and/or lacks free memory. 'Too complex' refers to the following variables:
  • A) The number of different models you've added to the scene.
  • B) The 3D Points number in the top right corner of Build mode.
  • C) The number and resolution of textures/materials.
  • D) The Movie/Photo effects you're using.
  • E) How many reflection planes you've added in the Reflection effect.
  • F) How many Spotlights that are set to Shadows -> Accuracy in the scene.
  • G) How many Spotlights you've selected in the Global Illumination effect.
To prevent your PC from becoming unresponsive when you start rendering a clip or an image, you should try to reduce the number of all of the above, in particular E, F and G. Alternatively, you should consider upgrading your hardware. There's more information here and here.
