Should you consider using this kind of texture import? Importing a new object from an image file To change the image resolution, use the top menu Image / Scale image. Lowering the color depth of our image allows to precisely control its render, as each color will have an equivalent in MagicaVoxel's palette. MagicaVoxel's Model editor works with a color palette of 256 colors. : Since MagicaVoxel v0.99.5, objects can now go up to 256vx in any dimension.Īnd why decrease the number of colors? Because the image we use has a color depth of 24-bit (RGB), which means a color palette of more than 16.7 millions colors. Why resize the image? Because each MagicaVoxel object cannot exceed 126 256 voxels (vx) in any dimension.Īs each pixel of an imported image fills 1 voxel of a new object, we need to resize down our image so its biggest dimension will be less than 126 256 pixels (px). To be able to import it in MagicaVoxel, we need to: The software's interface may seem complex, but don't worry, every step needed will be explained. Open the image in Gimp (if you get a dialog window about the color profile, click Keep). It may be that every separate asset in the game has a different color palette, which will make combining them in the MV editor really annoying unless you just get really fast copying colors.Let's browse, for example, and choose a simple wood plane surface like this one.ĭownload the small version: 640 x 427 pixels (px). It wont be fun, but it might be the only way for now. Go in and change the three numbers to match what they were in B this is the color cell of the B color value you want to keep. when A, the same color cell should still be selected. Go down to the bottom left of the color palette and expand the HSV sliders. use the '<' tool and click on the voxel whose color you want to select. I can look around, but if you want to do it the slow way i KNOW will work: to do it by hand, you have to do this: Okay, so I definitely think we're on the same page now.Īs far as I know, you cant merge palettes. How to I add more colors to the palate, from a list of colors form another model? (how do I merge color palets?) this means that any of those grey cells you can set to be exactly what the other model's original colors need.Īlso, if you want to copy a color, just control-drag it onto another cell, and it will duplicate the color value. this will turn any non-active colors into grey. If you want to see how many color cells are not being used type "pal mask" into the command line the bottom. To fix this, you will sadly have to go in and manually change each color EITHER on the voxels themselves to a new color, OR change the color in the palette that the voxels are drawing their color information from. If you copy and paste an object from another file into the one you're currently working on, the color identities from the new object will be mapped to the colors in your currently open file. the voxels that had their color values tied to that cell will change in real time as you change the colors. (if you're using the command line: the lower lefthand corner is 1, and it reads to the right, and then up)Įach of cells can be changed to a new color. When you're coloring a voxel youre just telling it which cell to draw the color from. The colors are saved with the model, but you can also export the palette and load it into new models (so you dont have to change the colors cell by cell) if you click on one, you lose whatever custom colors you made. there are presets the top 0,1,2,3 that are always the same. (However, if you open a new file from here, it will use the current palette). In every voxel file you open there will be a column to the left that is your color palette. Hmm, it might be easier for me to understand whats happening if you can link me to the models for stonehearth (assuming you didnt make these ones yourself) A direct consequence of this difference is that polygons are able to efficiently represent simple 3D structures with lots of empty or homogeneously-filled space, while voxels are good at representing regularly-sampled spaces that are non-homogeneously filled.īecause voxels are inherently blocky, voxel-art is like 3-dimensional pixel art. In contrast to pixels and voxels, points and polygons are often explicitly represented by the coordinates of their vertices. Instead, the position of a voxel is inferred based upon its position relative to other voxels (i.e., its position in the data structure that makes up a single volumetric image). This is analogous to a pixel, which represents 2D image data in a bitmap (which is sometimes referred to as a pixmap).Īs with pixels in a bitmap, voxels themselves do not typically have their position (their coordinates) explicitly encoded along with their values. A voxel (a portmanteau of the words volumetric and pixel) is a volume element, representing a value on a regular grid in three dimensional space.
