• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Blender Blender2P3DFSX encounter a problem with MDL export but not with X export

I encounter a strange problem when trying to compile a plane under Blender2P3D/FSX in order to obtain an MDL.
If I export this model by asking for an MDL, I get an error and the X file produced does not seem to be FSX compliant (dixit the log and MCX).
If I export the model in X and then with MCX I compile an MDL in P3D v5 format then there the MDL is well produced and it is perfectly visible under P3D v5 HF2.

For the details:
- i works with Blender 2.83.2 and Speedtool plugin from C. Lepillier (WAZOU RMB menu)
- the modeling is quite advanced and I created a Grey material that is assigned to all parts (mode specular)
- each element has been checked and its scale is 1.
- the toolset is manually finded and the modeldef.xml also
- for the moment I have no animation.

The ZIP file contains a log file withe two exports: 1) to hn-433.x and 2) to hn-433.MDL and an blend file (fuselage) which have this problem.

Hi Didier,
I tried exporting your model and it caused no problems. So I'm not quite sure what problem this model has on your setup. The only idea I got is that of the regional settings. If you're using the comma sign as decimals, try changing those to the American full stop and try again.
Since FS4.x each PC mounted by me is configured American full stop (dot as decimal separator) I just checked in case but this one is OK .
I have made a test with GastonJ example (fuselage.blend and his PBR material). I load his work and suppress his fuselage to append my hn-433 as obj. Then I try to compile with PBR material and I succeed perfectly :oops:

Perhaps it's in my specular material that I have a problem ...Well, I will created PBR materials and go ahead. At least I'm reassured about the 3D model :cool:
Thanks Vitus for your answer ;)
