I have just released a new build of my tools that supports Prepar3D v4 as well. Below it is listed what this means for the different tools.
As far as I know now the MDL and BGL format in Prepar3D v4 are the same as in Prepar3D v2, so there is no new file format you can export to. But ModelConverterX will automatically recognise the Prepar3D v4 SDK when installed. Also the Convert and Place Object Wizard has been extended to support Prepar3D v4 as output simulator.
The autogen configuration files from Prepar3D v4 can be read and you can thus select this version of the simulator as the active version. Besides that the Prepar3D SDK will be recognised when searching for certain tools.
Prepar3D v4 is added as supported version, which means you can select it as the active simulator version so that the effect files will be read from that effects folder.
For the Autogen Configuration Merger tool I have posted a beta release to the forum today as well. Once that has been tested better I will officially release it.
All other tools didn’t seem to require changes at this moment, but if you have issue using them with Prepar3D v4 please let me know.
