Hello and thanks for your work ! I'm using the last beta version of ModelConverter X to convert collada files to .mdl files. I create my 3d models with C4D 11.5 wich is my favorite professional soft, and then export them as .dae files to use them in MCX. It seems to work well (apart the fact there is no more "mass texture" button in the beta version, to convert bmp into dds ), and at the end I have a 12x5m .mdl textured object Then I make a library with the last beta version of library creator xml, put the .mdl file in it and save the library. No error message until this point. I precise that I'm working for p3dV2 exclusively and use the P3dv2 SDK. All the path seems to be OK in the options. Then I try to add the object I've just put in my new library in an airport using the very last version of ADE (1.61 5220). ADE add the library, displays the object in the list but consider it as a 0x0 m foot print object, and of course invisible, even if ADE places it on the airport. I'm surely missing something, I checked everything but can't find the solution. Thank you for your help.
