    • win64 : VCOMP140.DLL You may need to download this for windows: Visual C++ Redistributable for Visual Studio 2015
    • win64 : VCOMP100.DLL You may need to download this for windows: Microsoft Visual C++ 2010 SP1 Redistributable Package (x64)
    • macOS : unable to open the app: go to Security and Privacy panel to allow the app open.
    • macOS : Black screen: move magicavoxel.app outside the folder and then move it back.
    • macOS : too slow at retina resolution: disable Brush->Display->HDPI.
    • UI is too small: CTRL +/- to scale the ui. or change ui_scale in the config.txt file.
    • Multiple objects in the world editor: press TAB or double-click the background.

      • For small but strong light source (e.g. point lights), use Emit->Total
      • It is recommended to use lower image resolution (e.g. 640x480) when adjusting parameters
      • For better quality of final image, use more samples (e.g. 5000)
      • Not very robust for this version (has several potential artifacts)
      • If it is still too dark, do not forget to use Post->E to increase exposure
    • Fix several artifacts for Glass material
    0.97.3 - 06/05/2016
    • New Metal/Plastic Material with GGX NDF
    • Post Effects
      • Post->E: Exposure, when the scene is too dark, you can increase this
      • Post->V: Vignette
      • Camera->G: Gamma Correction
    • Pick up Sun/Sky Color from Palette
    • Better Quality of Soft Shadow
    • Sample->GI : on the top right, enable stochastic sampling for better indirect illumination
      • It's slower (~50%) and noisy (requires 3000+ samples)
      • Use it for indoor scenes, larger exposure, or final render
    0.97.2 - 03/02/2016
    • Export->bake: bake voxel mesh with ambient occlusion and soft shadow:
      • Example on Sketchfab
      • Must support the built-in renderer, if program crashed, recover model from cache/ directory
      • It may take from several seconds to half a minute, depending on machine, model, and sample number
      • Set sample number, direction and intensity of light sources in renderer mode
      • config->bake->perface: bake per face (pixelated) or per vertex (smooth)
      • config->bake->ambient: constant ambient color to make scene brighter
      • config->bake->gamma: for app with gamma correction, set it to 2.2 to avoid color washed out
    • New CMD odir: export all models in current folder, e.g. odir obj
    • Palette ALT+DRAG: swap palette color without changing model, make it easier to organize palette
    • Fixed a bug in .qb export
    0.97.1 - 02/15/2016
    • New Voxel Shader:
      • Supports GLSL based shader script to generate your custom volume
      • Shaders are in the new folder shader/
      • Try typing [xs wave] in console to start
      • Basic command format is: xs [shader name] [arg0] [arg1] [..]
      • If you want to run the shader multiple times in one run, use: xs [num] [shader name ] [args...]
    • New Brush Options:
      • [V]oxel Mode: 3D (Volume: Cube, Sphere), 2D (Flat: Square, Disc), Su (Surface, only operates on surface)
      • - Added hotkeys 1-9 to set brush size quickly
      • [C]enter Mode: supports both square and circle shape now
      • [P]attern Mode: can choose using either original model color or current palette color
      • - Can be applied on erasing and painting now
    • New Marching Cube Export Export->mc: export your voxel model as Marching Cube meshes (.ply)
    • Camera Control: use middle button to move camera
    • Cache Folder cache/: program will automatically backup model before quitting program or rendering model
    • Obj Export Pivot: fixed bugs for obj pivot, you can also set your custom pivot in config.txt->file_obj
    • Palette Command: added command pal mask to mask out unused color in palette
    • Fixed a little rendering bug with orth/iso camera, still not very robust though
    0.97 - 11/30/2015
    • Enhanced Brushes, Improved UI and File System:
      • Save and Open dialog for all Palette, Model, Export, Screenshot files
      • Face Brush: extrude surface by dragging with various modes
      • Voxel Brush: has been integrated with Cube and Sphere Brushes, working with mirror and axis modes now
      • Circle Brush: center voxel of circle is not operated; support even diameter size
      • HUD: voxel coordinates, volume size, face layers, circle radius are displayed in console now
      • Camera: added X+RButton to select camera focus center, and yellow button to toggle auto camera focus
      • Export: fixed obj export and more config options for isometric and 2d sprite export
      • Render: Light->0 is changed to pure color model; the ground in orth/iso mode will be infinity large
      • Multiple UI improvements
    0.96.3 - 08/15/2015
    • Matter->Glass: new transparent voxels with refraction and attenuation
    0.96.2 - 08/09/2015
    • Matter->Sel: per palette material setting (use Alt+LButton or LButton to select material)
    • New Emissive material; perfect mirror reflection (Rough = 0); over 8 light bounces
    • Folder path setting in config file; bug fixed for .obj export
    0.96.1 - 07/05/2015
    • Export->iso: new isometric sprites export
    • Export->obj: color based mesh simplification for .obj format
    • Model List: drag 'n drop folder to model list to change its root path
    0.96 - 05/24/2015
    • Renderer supports various voxel shapes (Lego, Marching Cube, Sphere, Cylinder) and rounded corners, colored grids
    • Camera supports stereographics projection, radial distortion, Escher Droste effect
    • Use F5/F7 to save/load current camera
    • Performance improvement and bug fixes
