maxtools V-RayMtl Converter v3.97 for 3ds Max 2013 - 2020

V-RayMtl Converter是max腳本，稱為“VRay材質轉換器”，可以將源材質轉換為其他特定材質，最大限度地保留基本材質特性，如漫射、鏡面、不透明度（包括濾光器）、光澤度、粗糙度、凸點、位移、自發光（發射）、半透明、反射、折射。此外，還保存了用于上述參數的所有紋理對于特殊的程序映射，只有在有模擬的情況下才會轉換它們，否則程序貼圖將保持原樣，如果目標材質不支持程序貼圖，則程序貼圖將被刪除。

V-RayMtl Converter 3 — is a new version of the maxscript known as "VRayMtl Converter". This next generation version was launched after the version 2.5 and has new different features and improvements: support for more materials, maps and other scene components, additional selection of materials for conversion, as well as more flexible options for converting and fixing the scene and its components.

V-RayMtl Converter converts the source materials to other specified material with the maximum possible preservation of the basic material properties, such as diffuse, specular, opacity (including filter), glossiness, roughness, bump, displacement, selfillumination (emission), translucency, reflection, refraction. Also, all the textures that are used for the above parameters were saved. As for the special procedural maps, they are converted only if there is an analogue. Otherwise, the procedural maps remain as they are or are deleted if the target materials do not support them.
