![]() This could be useful if you have different colours in different places and you want to switch which one you want to light up. In my case, selecting other colours than blue when my finished emissionmap was attached turned off the emission. this is why I'll keep the colour picker in Unity on white most of the times. Selecting the colour in Unity itself doesn't work as well when you want different colours emitting light on one texture, as Unity's colour option just adds a filter to your colours. When you've found the indexes you want to make glow, just give them the colour you prefer! Or if you want to, you could make the indexes white and use this colour option in Unity to make them any colour you want! I made the original palette the EmissionMap here, and made the colour purple. Just click on the part of your model of which you want to know the index. An easy way to find out what index you used is to use this little tool: It is possible to have two indexes of your normal palette to contain the same colour, and then only make one of them glow in the emission palette we're about to create. It's the place in the palette that's important here, not the colour. Now, find out what index of the palette you got your colours from. (Save it as something different though, it's annoying having to replace the original palette again.) Copy one of the standard palettes in the MagicaVoxel palette folder. Perfect if you want a full character glow effect (Like an angel, or when the player levels up/ gets a power-up.) but for this specific case, I only want the blue of the sword to light up. I recommend you activate it, HDR is really awesome.) (by the way, if you haven't enabled Bloom on your camera in Unity, your object will probably only light up like the sword in my scene view when you do this. Placing the original palette here will make the entire texture of the object light up. ![]() So I looked around in Unity and noticed there's an option to select an image for the EmissionMap in Unity. I wanted this gem to light up, but only the gem. Now for my sword, I had this little gem that has two colours. ![]() When you save the palette, here's what it looks like in MS paint.Īs you can see, it's just an image that's 256 pixels wide and 1 pixel high. ![]() Notice there's an option to save the palette. ![]() I just used the standard palette in MagicaVoxel. 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. ![]()
