3ds Max Vray Scene Converter to UE4

Hello guys, i making a mobile game on UE and I made some tool for optimization my workflow to export Scenes/objects. So i want to share it with community

It’s “one click” script to convert materials, baking AO, textures and lighting and to export and place in UE map

VrayMaterial -> UE PBR Shader:
Unreal - LEFT :))

Now it’s support Diffuse Color, Reflection, Refraction, Glossy, Fresnel checkbox and SelfIllumination. All Vray materials converts without any special editing for UE

It’s use One PBR shader for all materials that you have in scene. it’s used Vertex Color for Diffuse, Vertex Alpha for Ambient Occlusion. Metallic and Roughness used 3 UV map channel, and Specular, Emissive in 4 UV channel. Opacity overwrite Emissive if you have it :slight_smile:

My game model converted.

Emissive Test

Refraction test

now i make Texture processing for reflect/glossy (diffuse-> Vertex color already completed)

and i planned to do full Vray RawLighting and GI baking to Vertex Color and usual lightmaps

It’s really fast tool for export and preview models or for archViz

also it’s good for making LODs

it’s work with 3ds max 2014-2018 and Vray 3++

The most frequent question in BP section of AnswerHub is “I have an issue with <cast>”. The most popular question about Rendering is “I messed up importing my model”. Probably we will never find an universal solution for the first one but this converter definitely is the way to go for the second one.

21 version released - Refraction and Emissive Support, new Texture Baking to Vertex Color

25v released

Vray 3ds max to Unreal Engine Automatic Interior export - Version v36 - YouTube 36 version

Version 0.39 throws an “No “get” function for undefined” script error at baking AO into vertices. It unwraps and render the AO pass and then throws the error.
EDIT: “Vertex Color Pipeline” throws the same error.
Full “Textures Pipeline” with custom textures renders fine.
3dsmax 2018 with newest update3 and Vray 3.60.03.

v56 released, many features and improvements.

You are sharing it with the community, but it is 100% unusable without a LICENSE? That is SELLING, not sharing,… There isn’t even a demo or light version. There is a MARKETPLACE for SELLING… You got my hopes up. A really nasty thing to do with this particular subject…
Thanks anyways. I can’t afford $50 (and frankly it is preposterous anyone would need to in 2021. Maybe EPIC will buy your tool, THEN it will be ‘SHARED’’… ;")
