V-RayMax Converter PRO is the best tool for convert 3d scene (materials, maps, lights, cameras, proxies, modifiers, helpers, render elements, etc.) from other render engines to V-Ray and from V-Ray to Corona Renderer, and also for converting V-Ray and Corona materials to Standard/Physical/PBR/OpenPBR materials and to glTF Material.

Current version: 4.0061

Supported for conversion:

From V-Ray to:

• Standard / Physical / PBR / OpenPBR materials
• Corona Renderer
• glTF Material (3ds Max 2023 or later)

From Corona to:

• Standard / Physical / PBR / OpenPBR materials
• glTF Material (3ds Max 2023 or later)

Сonversion scope:

Full list of supported conversions.

Main features:

• Converts materials, maps, lights, cameras, modifiers, helpers and GI environment from other render engines to V-Ray and from V-Ray to Corona
• Converts clouds from CoronaSky to VRaySun and vice versa.
• Converts Night Sky system (Moon, Stars & Milky Way) from V-Ray to Corona and vice versa
• Converts Render Elements to V-Ray (currently supported Scanline RE, Corona RE, FStorm RE, Octane RE) and from V-Ray to Corona
• Converts V-Ray and Corona materials to Standard (Default Scanline) materials
• Converts VRayMtl and CoronaPhysicalMtl materials to Physical Material and OpenPBR Material
• Converts V-Ray and Corona materials to glTF Material (which is necessary for exporting to the .glb for corresponding 3d software: Blender, Gestaltor, Babylon.JS etc).
• Converts proxies (currently supported from Corona, FStorm, Octane) to V-Ray Proxy (static and animated)
• Converts V-Ray Proxy to Corona Proxy (static and animated)
• Converts standard Bitmaps to VRayBitmap and vice versa
• Converts standard Bitmaps to CoronaBitmap and vice versa
• Converts 3ds Max Physical cameras to V-Ray Physical cameras and vice versa
• Automatic configure ACEScg workflow in V-Ray
• Batch processing for multiple 3dsMax Scene (*.max) or 3dsMax Material Library (*.mat) files
• Programmatically interact with most converter functions using built-in maxscript methods (API), which allows you to use the converter without UI and in combination with other 3rd-party scripts.
• ...and more additional tools for fixing and adjusting the scene.

I'm currently working on a wave generator.

I ll give asap a dl link

New Shader test

Some foam tests

A set of tools to aid in the daily VRay work.

Updated to install with Max 2014.
WARNING: there is NO guarantee than any of the tools will work as intended, that they won't break your scenes in dramatic fashion, or skin your cat while you aren't looking.
This update comes purely because i needed the Physcam Autofocus for a personal test, and noticed they didn't install or run.
Having lost the source code for the encrypted parts, all i could do was to patch fix the (very ugly, with hindsight) installer and individual script launchers.
At least the autofocus routines still work in vray 3.0.
Feel free to let me know of issues, but also know that without a complete rewrite (quite unlikely), the fixes won't be forthcoming.

Updated for VRay 1.5 SP2.

The installer from V. 1.4ss - SP2 onward now has an option to automatically add the scripts to a ctrl+shift+alt quadmenu.
Notice it should append the scripts to whatever is already in the quadmenu (nothing, by default).
Please report any odd behavior, or undesired effect: it's a first attempt at the code, and may contain issues.

Anything to Physcam v.1.4: converts max standard cameras and viewports to VRay Physical Cameras, along with FoV animation.V.1.4 corrects a bug with camera views conversion, copies across clipping planes' ranges , and allows for individual camera naming at creation, rather than later by hand.

Matrix-Weighted Exposimeter V. 1.21 : very similar in principle to that of dSLR, it allows for different weighting of each slice/square in which the image is divided, as well as allowing a different range of pixel brightnesses to be chosen for the exposure (akin to real world lens filters).
Entirely customisable for behaviour.Now with auto-white balance and preset manager!
From V. 1.16 it supports exposure / White Balance animation through the script.
Please note this is not meant to be a frame by frame tool: doing so will result in flickering (like for standard dSLRs) and will likey lead to max crashes due to maxscript memory heap overload.
Keep previews small, Nth frame at around 1 second, and go in and refine by hand activating "Auto Key" from the max interface and exposing the problematic areas.
The Sample Rate calculator, new with 1.19, is an early attempt at DMC AA optimisation.
It will render a sample pass with whatever DMC AA (ONLY!) settings you have, analise the sample rate, and guestimate a new threshold value (AA noise threshold only) so that the BIAS setting may be met (+- 2.5%).
The BIAS indicates the pixel brightness average in the sample pass (where ~0 is min sampling, and ~1 is max sampling).
V.1.21 fixes the inconsistencies in vray versions when using QMC (now brute force) as a method for exposure GI.
