• 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.

FSXA Dark areas on the 3D Object

Hello everyone,

again I'm having an issue with this building I'm making.
As you can see in the screenshot, some darker triangular areas have appeared on my building.

This issue occurred when I started mapping the tower building (num 2).

Is there anything I can do?

I'm not sure if this is due to 3dsmax, Gmax or ModelConverterX.

My sequence is:

Design in 3dsmax --> Convert to MDL with GMAX --> Convert to BGL with MCX.

These are the warnings I always get:
WARNING: Degenerate poly detected in file (GMaxExport) mesh (Box024)
WARNING: Face vertex 0 x=-29.49999 y=27.90002 z=-5.261
WARNING: Face vertex 1 x=-29.49999 y=27.90002 z=-6.517242
WARNING: Face vertex 2 x=-29.49999 y=27.90002 z=-7


Thank you all.

Petros

It looks like there are some overlapping polygons or redundant geometry there.

You may be able to find the problem using face subselection, deleting the abberant face and welding the vertices/edges adjacent to them
 
Thank you for the advice, hcornea.

However,

I separated the tower building from the main terminal and re-exported as two separate files; LGML_tower.bgl and LGML_terminal.bgl .
The darker areas are now gone.

It seems that either of the three programs would not accept the number of polygons I've used in there.

BTW, is there a utility that can combine many .bgl files into one ?

petross, look at the error message. It's very clear. It says you have a poly whose three points all contain a common coordinate, or in your case, common 2 coordinates. I recommend you find and delete this polygon.

While there are a few methods to do this, the one I find simplest is to make a copy of your file to start with. Using only the copy...hide (in subobject mode, polygon) half the polygons. Then select the visible half and export. If you get the message again, then the bad poly is in the visible part. If not, its in the invisible part. Keep doing this with halving the half that contains the poly, and in a very short time you'll know the location of the poly. Sometimes I don't bother to find the actual poly, as once I've determined its general location, its just easier to rebuild that part of the geometry.

you have found your own solutions, but I generally don't see you taking the path that produces clean modelling (like in your post in which we find you had a bunch of internal tverts, but instead of eliminating them, you just adjusted them. Yes it works, but it keeps your geometry un-necessarily cluttered. Here's another case, in which you seem to think having the appearance of a good result is sufficient.

Not good practice.

I forgot to clarify...when you export as a test the selected polygons, use "export selected" option.
