V-RayMtl Converter
V-RayMtl Converter - the very useful professional tool for automating such a time-consuming process as converting of materials, maps, lights, cameras, proxy, modifiers etc. from different renderer engines (currently supported: Scanline (Standard), Raytrace, Autodesk Material, Architectural, mrArch&Design, Physical Material, Corona, NVIDIA iray (unofficial), fr-Advanced, Brazil Advanced) to V-Ray, as well as to reverse the conversion of V-Ray materials to Standard materials (which is very useful for game developers, 3d modelers, etc). Since version 3.998, the ability to batch convert materials in multiple * .max files has become available.
Current verion: 3.999
V-RayMtl Converter 3 — is a new version of the maxscript known as VRayMtlConverter.

******************************************************
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.

- improved handling of unexpected errors that may occur during material conversion
Your statements are unproven.
Give please examples of incorrect conversion Blend material to VRayBlendMtl.
Most likely you are using a hacked version that walks on pirated sites? But does anyone need to explain what the use of hacked software is fraught with ;)
None of the existing converters can provide you with 100% conversion accuracy (maximum 50%), but V-RayMtl Converter guarantees at least 90% conversion accuracy for all supported materials..

no even 50%
Useless for us. The blend amounts of Vray Blend Materials are wrong. This tool does not offer a 100% solution. Corona 5 -> Vray 3.6

Also there you will find the answer to your question.
Lossless conversion?
Specifically, is the conversion path (VRay -> Standard -> VRay) lossless?
Thank you!
Thank you for your words. We are constantly working to improve our tool and your feedback is very important and pleasant to us. Good luck and great creative work!
