• 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.

FSDS3 polygon shape/texture trouble

Could you explain why there is difference for the same object between fsds3 and fs9 ? I mean the interior of the 2 sides of the building, the polygon hadn't such shape as we can see and more i fixed no texture for the interior.

:confused:

btw no support from abacus ? No answer from them.

Thanks a lot


 
I think this is how FS renders polygons, so you can't really blame FSDS. It looks like you made the side of the building out of a single polygon, but FS doesn't like the concave parts, so it fills them in. Instead, try making the side out of several smaller polygons, so that within each polygon there is no concave area. You can still texture the sides of your building the same way.

Thanks a lot Martin.
I tried to build this object in an other way, by extruding. This time, only one side have this problem, but this time, it's visible too under fsds3...
So i tried too subdivising this polygon and it seems that there is problem again since by this subdivision, the polygon had less extra/false part, but still some of this part that was never created in the begining.
Ah ! and the tutorials are not numerous ! I need to correct what is my wrong method ?
 
Hi Martin,

This is weird and I don't think FS is wrong here. In the MDL file all polygons are already broken down to triangles. So I guess this triangulation is not done correctly in FSDS3 (or maybe it is MakeMDL, but then GMax would also suffer from it).
 
In fact, with the very first model, i flip to opposite one of this polygon and yes, it was now visible under fsds3. So no FS9 trouble for that, but wrong pratice from me !
Maybe i'd study more the end of this example :

It seems trouble like that, but how really ? :banghead:

:wave:
 
Hmmmm... I guess I assumed it was a FS problem becuase I remember running into the same problem a couple years ago... when I was using FSDS2. So, maybe it is a FSDS problem that was inherited from the older version. I guess it's a quirk of FSDS that has to be worked around.

I tried to select 2 points for inverting them and then flip polygon, without success :scratchch
FSDS3 lacks an other view, a rotated one, for selecting points more fastly... :cool:
I noticed too that flip isn't always done on polygon...Currious, buggy ?

Click to expand...

Before the floating point commands were there (so before Fs2002), it was certainly a problem of FS. I have seen it often back then that polygons that were concave showed up wrong in FS. You then had to split them, so that you got convex polygons.
 
I'm really asking is FSDS is a serious way...



It was my first attempt for pushing it under fs9, no old bgl since it was the very first, how is possible ? Under fsds, when i open the model again, there is no trouble, always like it should be ! :rotfl:
 
Ok, under FSDS3, there is a small bug that results in this error when you export the model. It doesn't happen all the time, and I'm not sure if Abacus is doing anything about it. Fortunately, there is a workaround.

1. Export you model as an .x file instead of as a .mdl file.
2. Start makemdl.exe, and load your .x file.
3. Export the model as a .mdl file.

Everything should work fine. I've been having this problem, so now I export all my models this way, since you can also choose different options while you are in makemdl.exe. It shouldn't work this way, but it's not that much more trouble either.

Ok, a couple more things about FSDS:

When you try to flip a polygon, make sure that you don't have any points selected, otherwise it doesn't always work the way you intend. Also, you might try the "snap-to-scale" feature to eliminate any duplicate points - just make sure you set your scale sufficiently small so that your project doesn't "shift". Finally, in the first example in this thread, it looks like you are trying to make the side from a single large polygon. FSDS doesn't handle concave polygons too well, so instead it is better to make 2 or 3 smaller polygons to fill the space. I like triangles, for simplicity.
