• extract the whole folder
• move “MagicaVoxel-mac.app” outside the folder
• move “MagicaVoxel-mac.app” back to the folder again

• chmod +x [directory]/MagicaVoxel-mac.app/Contents/MacOS/MagicaVoxel

• 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
• it can also be used for other purposes, like assets of same category
• However, features of importing and exporting anim are not fully supported yet

• materials are saved into vox file now
• if there is unsaved changes, the tiny button besides name field will become orange, click it to save
• program will ask for saving changes when open new models or close program
• click the title of each panel to close it
• Tool->Scale, Repeat, Rotate is removed, instead, use console commands “scale, repeat, rot”

• [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)

• only works in Pers/Free camera modes
• works for glass/metal materials (can get reflection/refraction from sun light)
• surface can also be lit by scattered light
• can create light shafts
• can create background with small fog density
• fog color mainly depends on light color and in-scattering color

• Emit->Power : Radiant Flux for Area Lighting
• Emit->Glow : Energy loss on closer surface
• Emit->Total : Total power for all voxels or power density

• requires “GI” option enabled for advanced effects
• only supports Cubic/RG/RE voxel shape
• for small but strong light source (e.g. point lights), use Emit->Total
• recommended using lower image resolution (e.g. 640×480) when adjusting parameters
• for better quality of final image, recommended using 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

• Post->E : Exposure, when the scene is too dark, you can increase this
• Post->V : Vignette
• Camera->G : Gamma Correction

• it’s slower (~50%) and noisy (requires 3000+ samples)
• use it for indoor scenes, larger exposure, or final render

• Example on Sketchfab
• must support the built-in renderer, if program crashed, recover model from “cache/”
• it may take from several seconds or 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

• support 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…]

• [V]oxel Mode : 3D(Volume:Cube, Sphere), 2D(Flat:Square, Disc), Su(Surface, only operates on surface)
• -add hotkeys 1-9 to set brush size quickly
• [C]enter Mode : suport 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
