ZEPETO BuiltIn Shader

👍 before you start, make sure that the \[ zepeto builtin shader docid\ uvvymdpom9qvatu frtsb ] is downloaded to the latest version the latest project file of version 3 2 12 and later includes the zepeto built in shader 📘 sample zepeto built in shader sample https //studio zepeto me/console/download/657fb8e4500c0631836abcce step 1 getting ready the builtin shader provided by zepeto is available through the zepeto/builtin path step 2 1 lit the lit shader is the default shader with only the detail normal removed from the default unity standard shader and the color grading option added 📘 please refer to the guide provided by unity \[ standard shader material parameters https //docs unity3d com/2022 1/documentation/manual/standardshadermaterialparameters html ] always work with the color grading option turned on for metallic, smoothness, and occlusion, the texture's r (metallic), g (occlusion), and a (smoothness) channels are used so that you can control them with a single texture when extracting textures from the substance painter, if you extract them with the unity hd render pipeline (metallic standard), the corresponding information is included in the maskmap link the textures to metallic and occlusion respectively step 2 2 litwithdetailnormal the litwithdetailnormal shader is a shader with an added detail in the lit shader and can use a secondary texture with different tiling 📘 please refer to the guide provided by unity \[ standard shader material parameters https //docs unity3d com/2022 1/documentation/manual/standardshadermaterialparameters html ] 👍 because this shader requires more computation than lit shader, it is recommended to use lit shader if you are not using secondary maps work with the color grading option always on in the case of metallic, smootheness, and occlusion, the texture's r, a, and g channels are used, so they can be controlled with a single texture when extracting textures from the substance painter, if you extract them with the unity hd render pipeline (metallic standard), the corresponding information is included in the maskmap link the textures to metallic and occlusion respectively secondary maps you can define an area with a detail mask that receives values from channel a you can use the number of textures efficiently by tying them together with detailalbedo's a channel step 2 3 cloth cloth shader expresses velvet material and allows additional control of sheen color and sheen roughness properties in common properties work with the color grading option always on sheen color you can adjust the glossy color on the fabric surface sheen roughness you can adjust the roughness of the gloss note that the changes based on the values of metallic and smoothness in the cloth shader are different from the lit shader step 2 4 customenv the customenv shader is a transition from the lit shader, which reflects an environment into an existing scene, to a shader that can reflect custom environments of your choice, such as high gloss or jeweled materials that are difficult to represent in the default zepeto environment work with the color grading option always on env cubemap applies the hdri resource to be reflected (the texture shape for this texture must be set to cube) env horizontal rotation rotates the hdri resource reflected on the material note that the changes based on the values of metallic and smoothness in the customenv shader are different from the lit shader step 2 5 fur the fur shader is used to express fur material, and fur related and lighting related properties have been added to the existing metallic and smootheness properties here, normalmap tiling exists separately from albedo, metallicsmoothness map tiling to express the recurring feeling of fur (the normal map affects the direction in which the fur is offset) work with the color grading option always on fur property furmap textures used in fur related properties; control the fur pattern in the r channel, fur mask in the g channel, and how much gravity is affected in the b channel fur length adjust the length of fur fur density adjusts the density of fur edge density adjusts the fur density at the edge of the object fur gravity adjusts the direction in which fur is offset lighting property fur occlusion color you can adjust the occlusion color between the fur (this gives the fur a sense of depth ) fur occlusion strength adjusts the strength of fur occlusion rim light mode select the light feel of the fur edge (none none, natural natural for albedo color, ambientlight environmental light for the scene, and userdefined custom) rim factor adjusts the area of light at the edge use directional fresnel use rimlight only for areas that receive light ❗️ caution for optimization due to mobile characteristics, we only use 7 offset passes calculated by fur shader therefore, if you increase fur length, the fur will not look natural when expressing long fur, it is recommended to model it large step 2 6 iridescence the iridescience shader is a rainbow colored film coating shader that is visible when a thin film coating layer is placed on the surface of an object the rainbow colors on the film coating layer cannot be set by the user and are automatically generated by the calculations presented in hal open science https //hal science/hal 01518344/document if color grading is turned on, the iridescence representation may not show up well thickness thickness of coating layer η2 refractive index of film coating layer medium η3 refractive index of base object medium κ3 the value of calculating the internal complex refractive index η3 + i κ3 of the base material controllable scale adjusts the value that forces the angle of light spread across multiple layers to scale note that the changes based on the values of metallic and smoothness in the iridescence shader are different from the lit shader 👍 when using the iridescence shader, it is recommended that you play around with each of the properties to get closer to the look you are trying to achieve step 2 7 sparkle the sparkle shader expresses light reflected from a thin layer of flakes scattered on the surface of an object it is used to create effects that vary with light and camera orientation ❗️ caution the noise resource is built into the shader itself and cannot be modified separately, but you can adjust the feel in the properties below work with the color grading option always on noise intensity adjust the degree of glitter noise concentration adjusts the area where the glitter is visible noise size adjust the size of the glitter noise density adjust the density of glitter step 2 8 toon 📘 please refer to the following guide toon shader docid\ vt480xjhfzzz3ok7cfr step 2 9 hairalpha the hairalpha shader is used to create hair, and it has been modified to express alpha support and bridge (the part that is not affected by hair color) in the existing zepeto hair shader the basic material setting is connected to the hair texture included in the zepeto app, so unless you're using the alpha texture you want, use it without any modifications for hair, the default rendertype is transparent, so adjusting the render queue can cause problems by overlapping with other transparent materials therefore, do not modify the render queue when creating hair, it is common to set up multiple materials and use different render queues to resolve alpha sorting on overlapping meshes in this case, instead of setting multiple materials, you can adjust the vertex number with one material (render queue 3000) ❗️ caution usually, when rendering transparent mesh, the vertex numbers are drawn in order from low to high at this time, the mesh drawn later looks like it came out in front while 3d modeling programs do not allow you to modify vertex numbers arbitrarily, the order in which you combine meshes (combine in maya, join in blender) will set the vertex numbers of the later meshes to be higher, so you can solve alpha sorting even in a single material 📘 please refer to the following guide how to solve transparent material alpha sorting issue docid\ wmkgaa5 exe9qsci5kvnx
