Conversion of 3D models from Kaydara format (.fbx) to VRML 3D graphics (.wrl, .vrl, .vrml etc.) should be doable either with some of the 3D modeling tools that support both of these formats, or alternatively with some kind of dedicated converter for 3D models, such as PolyTrans.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
