If you have any questions just post in the comments. Right after you do that the black texture the original cube had assigned will be instantly replaced by the Normal Map we just baked from the Bump Map.Īnd that's about it!, you can now save the Normal Map and delete the cubes (or keep them if you want to compare the textures). Now select the dupe (the cube which has the Bump Map) FIRST and then the other cube (make sure you select them in that order!) and click the "Bake" button from the bake tab. Move the duplicated cube in the exact same position as the original one (this is important because if they aren't in the same place the bake will not result as expected). In the Properties panel scroll down until you see a tab called "Bake", open it and check the "Selected to Active" option and in the Bake Mode list select "Normals". In the Shader editor set up the material to use the image texture: Select the original cube and assign it a new texture with these settings: Move the duplication somewhere near, assign it a new Material (with the settings at default) and using an Image Texture node to set the displacement using these settings: In Blender, we have two different ways we can use displacement. Two ways to use displacement in Blender and the difference between them. Therefore, you dont see displacement maps used as often for real-time applications or games. This will ensure the normal information from the original material is maintained. Since displacement needs a lot of geometry it is also heavy on performance. Add in a Bump node and feed in the existing normal map into the normal input of the bump map node. Select the default cube, unwrap it and duplicate it. Create a new mapping node and feed that into the scratches texture node, this will allow you to make scaling changes later on. Knowledge on what Normal Maps are and how they work. Knowledge on what Bump Maps are and how they work. Experience using Blender (specially texture baking). Unity Interactive Map Shaders This tutorial is. Make sure you met the requirements below! Both normal maps and bump maps add detail to the surface texture of a model in the form of bumps and dents, making the surface geometry appear a lot more. Samples a Texture 2D and returns a Vector 4 color value for use in the shader. Today i will show you a quick tip to convert Bump Maps into Normal Maps only using Blender. Navigate to the folder containing your maps. The add-on uses a custom Blender node-tree to drive the export. To create shortcuts to your favorite games!
