![]() If you’re creating maps to use with Quixel dDo you’d want to bake a tangent space as well as a object space normal map, while Substance Painter expects a tangent space and a world space normal map. Cages can be used with Cycles and XNormal, Blender Internal doesn’t support them unfortunately. A fast and easy way to create a cage is to duplicate the lowpoly mesh, scale it up using Alt+S in edit mode and correct intersections/weird topology by hand. This is basically a duplicate of the lowpoly mesh which is modified so it encapsulates the high-/lowpoly completely. Tip: To bake maps using Cycles make sure your lowpoly (or highpoly mesh if you have no lowpoly version) has a material assigned to it and there is an Image Texture node (with the texture you’re intending to bake to) somewhere in the node tree, it doesn’t even have to be connected to any other nodes.įor best results with complex meshes I recommend to use a cage. Also make sure the model you wish to bake has a image assigned to bake to, if not, go to edit mode, select the mesh and add a new image in UV/Image-Editor (“Image -> New Image”). It’s also important to select the highpoly first and then shift-select the lowpoly to add it to the current selection and make it the active object. Tick “Selected to Active” if you’re intending to bake down the details from a highpoly model to a lowpoly one and make sure the lowpoly has proper UV coordinates. You can choose the type of texture you want to bake from the “Bake Mode” drop-down The “Bake” settings in Blender can be found at the bottom of the Render tab of the Properties window and change according to the render engine you have selected: Depending on which software you’re using later for texture creation you need slightly different maps, however most of the time a normalmap and an ambient occlusion map are the bare minimum for Substance Painter/Quixel dDo.įor baking I usually use Blender Internal, Cycles or XNormal, which is a really powerful, free application and produces superior results to Cycles in some cases. ![]() If you’re not a friend of the additional work required to get a lowpoly model or just want to showcase your highpoly one, don’t worry, Sketchfab handles models up into the millions of polygons just fine!Īfter the model is finished and unwrapped it’s time for baking maps. Based on this a lowpoly version of the model is created and UV unwrapped. Since I usually create assets for real time use cases like games or augmented reality applications, I first create a highpoly (=high polygon count) model with lots of details. So let’s start by creating the model in Blender. That’s pbr in a nutshell, please refer to the links above for more detailed explanations. You can easily turn a roughness texture into a glossiness texture by just inverting it and vice versa. ![]() The roughness/glossiness maps are black/white textures used to control the “sharpness” of the reflections. White parts of the metalness texture mean the material should be treated as a metal and black parts are non-metals, easy as that. The main difference is that the Specular Workflow utilizes a “specular texture” (a rgb color map) to control reflection amount/color, while the Metalness Workflow relies on a “metalness” texture, which is basically a black/white map. They both make use of a base color texture (commonly referred to as “albedo”) as well as a normal- and ambient occlusion map. What’s important to know is that there are two workflows, commonly referred to as “Specular/Gloss” and “Metalness/Roughness” workflow. We will be exploring how to use Quixel Mixer to texture a stylized 3D model from Blender 2.I’ll skip the theory behind physically based rendering/texturing for now, since there are very good explanations around, and freely available to anyone. In this Quixel Mixer tutorial for beginners you will learn how to texture a stylized 3D model made in Blender 2.9 with Quixel Mixer
