• 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.

Textures trembling and shaking in scenery

Hi guys! I'm newby in modeling. I know similar questions have been asked here but I didn't find answer to my problem. I started topic here because I'm almost sure I made something wrong with first steps. Maybe textures doesn't appropriate enough.

I made an airport for Prepar3D v4 and everything seems perfect for me except apron and runway textures. They are trembling and shaking. Not flickering.
- I made model in SketchUp2018.
- export it in *.mdl (also I tried *.obj. Result is the same.).
- in Model Converter X, using Ground Ppolygon Wizzard *.mdl file was converted into .bgl.
I tried different variations with layers numbers. Negative, different for every layer. Doesn't work.

Scenery

Maybe someone had such problem? Because I'm almost exhausted. I've tried a lot of things. But crashed and burnt.

There was a problem in MCX for GPs using P3Dv4.4. Download the latest Development release and try again.

Unfortunately doesn't help.
Maybe I made textures in wrong format? I made 24 bit .bmp and convert it to dds via MCX. Is there some specific requirements (except power of 2) for ground textures?

Hi Andrew:

Inspection in ADE v1.76x of your 'Airport' file:

[63356-UKLR-Rivne install path]\UKLR-Rivne\UKLR\scenery\UKLR_ADEP4_AP.bgl

* Altitude for ARP, RWYs and T-WAYs match the 'central' airport flatten Altitude at 230.124 Meters

The above airport-specific XML objects would not be a basis for ground object display anomalies you describe in your OP above.


Inspection in SDK TMFViewer and via Patrick Germain's CvxExtractor of your CVX vector BGL file:

[63356-UKLR-Rivne install path]\UKLR-Rivne\UKLR\scenery\UKLR_ADEP4_AP_CVX.bgl

* (2) 1-piece custom CVX objects :


NOTE: CVX Object types are documented in:

( [Flight Simulator X install path]\TERRAIN.CFG

...and:

* P3D SDK Docs:

The above airport-specific CVX objects would not be a basis for ground object display anomalies you describe in your OP above.


Inspection in MCX G-Poly Wizard of your 'G-Poly' file:

[63356-UKLR-Rivne install path]\UKLR-Rivne\UKLR\scenery\UKLR_ADEP4_AP_GP.bgl

* G-Poly Altitudes at 0.00 AGL aligns with an airport flatten Altitude at 230.124 Meters

* "Group Polygons @ 500 Meters" may- or may not- be a basis for the ground object display anomalies you describe in your OP above ...in older versions of MCX G-Poly Wizard


FYI: A ground object anomaly is reported by users of MCX' (older) G-Poly Wizard if "Group Polygons @ 500 Meters" is checked

AFAIK, that was recently 'fixed' by Arno; you should now try re-importing / converting your source files into MCX' (Dev.Rel). G-Poly Wizard



Inspection in MCX ('normal' import mode) and via Scruffyduck's BGL2XML of your 'static scenery object' file:

[63356-UKLR-Rivne install path]\UKLR-Rivne\UKLR\scenery\trails.BGL

Flat 3D textured objects exported from MCX as FSX or P3D MDLs are likely to be a basis for the ground object display anomalies you describe in your OP above.:alert:

CAVEAT:

Even when P3D "Z-Bias" functional attributes are applied to a mapped texture Material on a P3D MDL in MCX, "Z-Buffer Fighting" ground object display anomalies 'may' still be visible in P3D at run time in "TOP DOWN" camera view mode, and/or other P3D run time camera view modes within 'shadow' areas ...when superimposed on default or custom land class terrain textures (including custom photo-real textures).


You should instead try importing / converting the ground-type objects in these latter BGLs via MCX' (Dev.Rel). G-Poly Wizard. :pushpin:

Hope this helps ! :)

IMHO, just try importing the Trails and Ground BGLs into MCX' G-Poly Wizard ...and output them as P3Dv4.x G-Polys. ;)

Looks like I've solved this problem. The reason was in wrong texturing. I changed dimension only using pins. But it's not right and we should use dimension windows. Thx to everyone for responce!

Indeed, a self-tiling texture may create display anomalies such as Moire' patterns when sizing of a mapped texture image is too small, artifactually causing excess "texel density" relative to the pixel mapping size in a context of other local textured objects. :pushpin:

Hello to all, hopefully not too old thread here. I have a similar problem but with FSX sim. The runway and apron needs to be free of flickerings and flashes. I tried with ADE and MCX, last versions and not a success.
The UKLR is a freeware named as 63713-UKLR-Rivne found from the website. How to fix it?
I also found the Markings.mdl file shows runway 29 instead of 30. Anyway, what's important now is how get rid of the flickerings.

After importing Trails and Ground BGL files with MCX and converted as FSX, it didn't work for me. I might not doing the correct procedure. The UKLR still have flickering, flashing and bleeding with FSX sim.
