![]() ![]() We also turned on our Grid, which you can find in the bottom left of the screen, to make it easier to see the voxels. For ours, we created a 4x4x4 set of voxels directly in the center of our lantern base. Now that you have your tools ready, we can create a set of voxels for the light. Of course feel free to try other colors to create cool effects! For this example we used a very bright yellow to simulate the look of a flame. This is the color the voxel will be when you add it. Then select a color from the Palette window. This gives you the ability to add voxels to your model. To add voxels select the Attach tool from the Brush window. Now that we have the base for our lantern, let’s add some voxels to the center for the light itself. In this example we will be turning this model into a lantern that shines light to its surroundings. You can find it in the project window on the right side. For this tutorial we will use a the “8x8x8” sample model that comes with MagicaVoxel. There you can find a step by step tutorial on getting MagicaVoxel running on your computer.įirst let’s open up MagicaVoxel. If you need help installing MagicaVoxel, view our previous tutorial How to Install MagicaVoxel. This tutorial uses MagicaVoxel 0.99.6 or newer. ![]() The center voxels will emit light onto the floor and the outer case. However, using an Emission material will allow you to emit light from a specific voxel to create lighting effects like a light bulb or neon sign. For this tutorial we will be creating a lantern out of a sample voxel model that comes with MagicaVoxel. This window allows you to adjust the global lighting of your scene and behaves similar to the way the sun behaves in the real world. This is important to understand because there is another window in MagicaVoxel called Light. In 3D modeling, adding Emission to a material will make it appear as a visible source of light in your scene. If you did any searches prior to this you may have seen the word Emission being used. In this tutorial, we will show you how to make lights using the Emission material inside of MagicaVoxel. Whether it’s making a streetlight for a city or the headlights on a car, lights can enhance the visual effect of your scene. OBJ format to export my models from MV to Unity.If you make voxel models in MagicaVoxel you make have come across a situation where you need to create a light. Tried to override texture settings for Android as suggested, but it failed (by the way I couldn’t find any RGBA 3 bits, tried with 32 bits).īoth of my objects (MV mesh and Unity cube) have a Mesh Colider īoth textures (including the PNG palette generated by MV) are read/write enabled Or is it a problem of texture compression in Android, as I read here : ? So, if the problem has to do with UV mapping, why does it work at Unity runtime but not in Android ? Sorry if my explanations are not that clear, but MV users know what I’m talking about. It generates a 256*1 pixel PNG texture, each pixel corresponding to a palette color, and each voxel using one of these colors. In this case, GetPixel() works fine, even in Android.Ĭould this problem occur because of the way MagicaVoxel meshes are textured ?Īs you know, MV does not generate UVs on its meshes. I made a test with a regular cube created in Unity, and using regular Material and texture. More precisely, it fails on objects imported from MagicaVoxel. ![]() But it fails to read the pixel color in the Android build the color read is always dark grey. It works fine when running the game in the editor. I’m trying to retrieve a pixel color with a raycast, in order to « analyze » the environment of the player. I’m making a 3D game using voxel graphics, all of them being made with MagicaVoxel. ![]()
