About conversion:

None of the existing converters can provide 100% accuracy of the conversion due to the fact that the principle of the different renderer engines differs, and sometimes differs significantly. In this regard, the physical parameters of materials are also significantly different. But despite these differences, we tried to achieve the maximum possible accuracy of the conversion, which the our plugin provides an average of 90-98%

V-RayMtl Converter converts the source materials into other specified material with the maximum possible preservation of the basic properties of the material, 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 are saved. As for 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.

NOTE: I hope you remember that for the conversion of materials between different renderer engines, a prerequisite is the presence of these renderer engines in your system.
