• 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.

Brilliant work! I am a fan of LIDAR with photoreal myself. I have made a number of small sceneries myself, based on LIDAR data obtained from opentopography.org . Most of their datasets were fairly small, and from the USA only, but you can get some fascinating results when combining LIDAR with photoreal. The first one I made was a mesh and small photreal for the meteor crater in Arizona (Barringer Crater), and it was amazing how much detail you could see with a 1m mesh created from 0.5m LIDAR. You could see individual rocks and crevices quite clearly.

Wow, this looks amazing... Makes me wonder about the performance. Autogen *should* be more performance friendly than dedicated 3D structures, but how does this pertain to a mesh-based scenery such as this?

Thank you! Yes, i am using 1m mesh resolution too, the detail is really amazing

I have turned autogen off and placed a large autogen exclusion shape over the entire area (to remove bridges, etc.), from the surrounding airports i removed all buildings and performance seems very good. I was able to set the LOD Radius to 8-9 without any problems. Never had any OOM errors. Only texture loading is a bit slow, due to very large ground textures (~1.5 GB / 100sqkm)

How does one compensate for the blurry/stretched sides of buildings? I would think major amount of time or $$$ to resolve?

Unfortunately this is not really possible. It depends also on the angle of the buildings in the satellite image. Since it is only terrain and no buildings, etc. the taller the buildings are, the more stretched the sides will look but it's only really visible on low altitude or on cities with highrise buildings.

Isn't that what FS2020 doing with there scenery?

I think FS2020 does it similar like google earth. It generates scenery from photogrammetry, it has the advantage that it already include the textures. In FSX terrain data has only XYZ information, no color information. I am using LIDAR data from a digital surface model to generate a similar effect

It looks really impressive and strong!

Have had some experience with LIDAR data myself, the level of detail is amazing. It would of course be very nice if one could derive 3-D models from the data. But anyway. The east of Germany can tolerate good scenery, there is nothing else :)

Thank you! I have tried to create a more accurate model from google earth 3d scenery with photogrammetry software and it looked indeed better as the current model, but it was way too many work effort.

Awesome work goin' on there. Luv the ground texture refresh. Looks like the world has melted! o_O

Thank you. For the ground textures i had to oversharpen the images to create a more realistic look, it seems FSX makes the images more blurry then they really are
