How to convert VRML (VRML2, VRML97, X3D) to Maya (.ma,.mb)?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

VRML

VRML2 ("Virtual Reality Markup Language") is one of the very best of non-MCAD file formats, little appreciated and lost (mainly) to the annals of time. Many people (wrongly) believe that FBX is the primary "translation file format" but VRML2 pre-dated it by at least 10+ years and has equally good or better functionality (and in an open, non-proprietary specification). It was supplemented or augmented by the X3D (XML-based) file format in the mid 2000s. The Web3D Consortium supports the evolution of VRML2/X3D and of its acceptance as ISO and IEC standards.

Without getting into specifics, VRML2 can be considered a "rich file format" in terms of its functionality and capabilities, yet few software programs fully utilize all of that functionality. It could have, and should have, become the defacto "universal 3D file format" for data translation and long term storage but it did not have the clout nor marketing dollars that other newer formats had such as from Autodesk (FBX, DWF), Sony (COLLADA), Adobe+Intel (U3D), Dassault Systemes (3DXML) and others.

VRML1 and VRML2 are 3D file formats with a long and complex history. They were originally developed in the mid 1990s to define 'interactive 3D worlds' on the then-new World Wide WEB. However, statistically speaking, VRML2 became more well known as a high quality "data translaton and storage" file format, partly due to Okino pushing it as such a standard in the industry. It was implemented by a good number of 3D software packages and hence became a "reliable back door" to convert 3D assets out of those packages before FBX, DWF, COLLADA, U3D and other similar file formats came along in the mid to late 2000s, or glTF in the late 2010's.

It is also known as VRML2, X3D, Classic VRML, VRML97, VRML1 and Inventor2.

Maya

Maya is a well known and respected DCC/Animation system which had originally been developed by Alias Research in Canada then purchased by Autodesk in 2006 after Alias went bankrupt.

As is very little understood, no program on this planet can read or write Maya ".ma" (ASCII) or ".mb" (binary) files because the full geometry modifier stack of the Maya software, and its various plugin modules, are needed in order to properly evaluate the file before it can be rendered. This is what forced Okino to write its well known PolyTrans-for-Maya system, which allows for all Okino 3D converters to run within Maya itself. For example, if you want to convert to/from CINEMA 4D (.c4d files) then you would do so entirely inside of Maya.

Due to multi-decades history, Maya users are notorious for using the OBJ file format to convert files to/from other software packages just as 3ds Max users wrongly use the 1985-era .3ds file format. OBJ is an "okay" file format but there are much better or more preferred methods to convert the data.
