MagicaVoxel, the popular GPL Voxel modeler has released an update with a list of interesting new features.

1. Frame Based Animation
   • support up to 24-frame animation
   • [Ctrl+Drag] to move frame, [Ctrl+Shift+Drag] to duplicate frame
   • press on the prev/next button to play animation (you can also change time step)
   • drag and drop multiple models to import as animation

2. New Interface

   • [New inputs]
   • iFrame : current frame index
   • iNumFrames : total num of frames
   • iIter : current iteration index
   • iRand : a vec4 random number updated every iter and frame
   • [New Options]
   • -n : specify number of iterations, eg. xs -n 8 [shaderName]
   • -prev/-cur : specify input frame, -prev for previous frame, -cur for current frame (default is -prev)
