• 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.

Feature Request: Support for 32 Bit Index Buffers

Hi Arno,
Currently, MCX doesn't support any models with index buffers higher than 16 bit. Dovetail Games' Flight schools aircraft models have been stepped up with 32 bit index buffers which are beyond the scope of what FSX can handle.

Would it be possible to add this feature? Currently, when attempting to open the models, MCX gives an "Object reference not set to an instance of an object" error...

Thanks,
 
For context, DTG added a INDX riff section that consists of 32 bit indices (count is size of section / sizeof(UINT32)) and a VTXC section, which appears to be 4 bytes per vertex, so I'm guessing this is a 4 channel, 8 bits per channel vertex color.
 
I'm sure it would be a good feature when there's a way to add content to DTG sims, but aren't we jumping the gun a bit?
 
I haven't checked the new sim yet, but if possible I'll add support.

It would be really interesting if there is an SDK to export as well.
 
Thanks Arno.

Unfortunately there isn't going to be one. DTG aren't so keen with 3rd party content for Flight School, but they may release an SDK for the upcoming simulator.
 
Hi,

Support has been added now, just download the new release tomorrow.

It was actually quite easy, since P3D v2 already had a 32 bit index buffer, but they call the section IND3 instead of INDX. The warning for the VTXC section is also suppressed, although I don't really read those colors.

The model shows in MCX with a lot of reflection, so it might be they use a different shader. That's not reflected in MCX for now.
 
Hi Arno,

Thank you very much. Will try it out for sure.
Glad to know that you didn't face too much difficulty with it!

Thanks again,
