The HDR Light Studio 4.1 Demo Edition is save and render disabled, but includes all other functionality and plug-in connectivity.
Try it in Standalone mode - importing your OBJ, MI or Collada files and playing with the LightPaint feature - see how intuitive and productive this lighting method can be.
Try it in a Live connection with a partner 3D app and experience for yourself the power of interactive image based lighting - see the lighting evolve directly on your scene, seeing the light interact with your materials/shaders.
Existing HDR Light Studio users should note, installing the HDR Light Studio 4 Demo Edition will disable their previous version Live plug-ins. These can be simply re-enabled by running the old installers for those plug-ins. Your license file will not be removed in this process.
