• 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.

P3D v4 Something changed with GP-shadows?

Hello,

back in July I experimented with the P3D Groundpolys for my Mestia project. Everything went fine once I found out that you need the setting "shadows - receive - buildings" to turn on.

Now in my Telavi project, I did exactly the same steps and used the same material settings like in the Mestia project. But for the life of me... I can't see any shadows:

I attached the material setting templates of both UGMS Mestia and UGGT Telavi.

Then I took the UGMS groundpoly.mdl and used the development release of the ground polygon wizard and rebuilt it. Now I also don't have shadows there. I would like to try it with an older version of MCX if this is maybe the problem but I don't have an older version and the stable release is too old...

@arno do you think, that something could have changed there? Maybe I can try with an older version (around July 17) again or am I missing something completely?

I can't think of any changes I made since then, but I'll double check in the source code if there are differences since July.
 
Hi,

I checked my code and since July I only made two changes. One was in mid July and that was to disable drawcall batching on the P3D output, since that gave trouble. The other one was to update the form and use a new control to set the coordinates. But I doubt these two things can result in your issue.

Do you still have the old BGL file that works? Maybe we can check the differences, e.g. a material setting that changed or so.
 
Hi arno,

thanks for checking. I did some further tests also. First I ruled out that it has something to do with my simulator settings because I can see shadows on my other airport with P3D-groundpoly. But then I tried it anyway... i checked "Shadows - Receive - Simulation Objects" and voila:

Strange enough it was not only the shadows were missing. The overall look and feel is completely different:

So... on my old airport the GP seem to be a "building" and now they are a "simulator object". Is that a P3D v4 thing or a MCX thing? I can live with it when I know it but I am not sure, how many people have all those lighting options turned on as they are not default. If you want, I can send you those old files.. but it don't seems to be a material setting issue.
 
I have no idea what P3D calls a simulation object or a building. In both cases you placed your ground polygons through a BGL file I assume?
 
Yes, my groundpoly-workflow is always identical:
  • export groundpolys from blender in dae format
  • import it into MCX and adjust all the material settings
  • export it as a P3D v4 object (mdl)
  • open that mdl with the ground polygon wizard and produce the groundpoly.bgl
 
Hello Guys,

I'm Having same problem, with the new MCX, it gives me empty triangles in middle of my GP!
I'm stuck with my scenery !

Thanks

That's not the same problem of course ;), that's a known issue in fact. You probably have some quite large polygons. Try to split them into smaller bits in your modelling tool and all triangles should be there.
 
I have no problems doing exactly the same as David (but starting out from a ADEgp bgl that I have to merge, convert into a P3Dv4 mdl and only then use the GPwizard) and I am using the development version of Nov 21.
But my polygons are at the most 3km long and in the GPwizard spliced into 100m chunks (grouping into 500m polygons not necessary).
 
Roby, probably ADE already sliced them for you. There is a but that if you come from a modelling tool with long polygons you sometimes loose some triangles.
 
No,Arno, I do not let ADE do that. The ADE_GP.bgl consists of models per layer.
I let the MCX GP Wizard do that.

Sorry Arno, I made a mistake in reading the post !
