• 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.

Question: photoreal groundpolygon where to start

Hi Marc,

Looking at the screenshots I do not really find them blurry. Of course when you zoom in a lot, you will see that each pixel is 1x1 meters. That is what I am seeing in your most zoomed in screenshots. But the images themself still look sharp for the resolution that they have. Zoomed in that part you would need more than 1 meter per pixel to still get a sharp result.
 
Hi Marc, sorry for my flawed assumption...I see that you are indeed decorating polygons.

I guess the path I would take is to explore alternate resolutions to determine how the goals you have fit the images. If it was me, I'd take a subset of the project, and go back to full size imagry, cut the image appropriately and design some polygons with true .2 m/pixel resolution. do enough to assess. Could be based on the features you are attempting to display that you need this level of detail.

You also may want to consider building some polygons that have more specific purpose to lay over the basic 1 meter polygons...such as a set of polygons just for the road that seemed flaxy in your screenies.

Hi Arno and Bob


When I'm on the ground, I just have the feeling, that the apron and the runways are "floating", that I would fall, if I would move onto the grass. When I have a look at the FS9 standard textures, they have a sort of "points" (noise?). When I use the standard textures, I really feel, that I'm on solid ground.
Also on straight lines, you can see the steps very clear which doesn't look very nice. How would you avoid that? Would you "draw" them in gmax to add it for another layer?


Best Regards

Marc, I just glanced thru this thread to see for sure if you are designing for fsx or fs9. If fsx, did you break up your polygon into 100m peices?

As far as the bad jaggies, I think this can be improved with higher resolution or drawing more polygons with individual decoration, like you suggested.

If fs9, there was something that made it feel "floaty", but I can't quite remember what it was...mips perhaps? something....I don't remember.
 
Hi Marc,

You would have to add your own noise layer if you want noise over the texture. It is only done by default for mesh textures (which is what the default grass is).

I don't think you can draw lines with textures like this. Even at a resolution of 20 cm or so it will not look like smooth line in FS. So I prefer to draw them on top as polygons.
 
Hi Arno and Bob, sorry for this late answer...

I tried to put a noise layer on it, but the frames sank drastically (the texture was too big). What size would you take for this texture and what size should I set in gmax (I set 10m for 256x256 which was far too much).


Thanks for your help, you're great! ;)

Best Regards

Hi Marc,

For the airports I used a noise texture with, I just had a small texture (128x128 or 256x256) with random noise in the alpha channel. I then repeated that over a polygon that covers the entire field.

As this is only one polygon it should not really influence the performance. I could never measure any difference for one polygon and one texture extra.
