Import ldr Model into Unity issues.

[Philippe Hurbain]

Hi (and welcome here!)

I checked the ldraw xml file and I have the most recent version. 

Are you sure? The version that I installed here with Unity is dated 2020-02-02 and doesn't contain mapping for parts 65634, 65635 and 66727. Latest one is stamped 2020-12-23.

Unity LDraw.xml is located in C:\Users\{your user name}\MyFirstGame\Library\PackageCache\[email protected]\Data
Keep a backup the original one if the new one doesn't work (it seems to be fine here)
