• 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.

Photogrammetry with a hard surface / collision factor

Hello,

I implemented in Dev Mode a Photogrammetry area but it does not seem to be a hard surface. I wonder how to make it have hard surface properties for aircraft to land on it as well as cars to drive on it.

Thanks

make sure to enable road material in blender in the MSFS material properties to make it a hard surface

Ok thanks, so I think each of the Photogrammetry 3D files should be edited in Blender one by one. MSFS dev mode does not assign hard surfaces or collisions to the imported models.

I've still had very little success with this. My models are baked to one material so I only need to change it one one place, but I've tried every combo of enabling "collision", "road", "collision & road" and it doesnt seem to have an effect. I've see some people do this successfully ... there is a flying avengers aircraft carrier for example. The author told me he enabled "collision & road" but only for the top surface material. I tried something like this with no luck.

There must be more to it under the hood.

Does MSFS limit the effect to a certain polygon count? I've created an invisible collider with a poly count reduced to about 170, but even that didnt really seem to have a consistent effect (I thought I might have had some collision, but can't tell if it was really with the terrain lying just beneath on certain areas)..

Do the collidable polys need to lie within a certain angle range of horizontal? (this would be a weird design choice, but I'm drawing at straws)

The schema files in the sample directory for Collision_Object seem to refer to a bunch of primatives (i.e. sphere, rectangle, cylinder). Is that the way MSFS really wants collisions to work?

I've been working on some scenery for Yosemite and really want to land a future helicopter on top of Half Dome... begging for advice from anyone who's gotten an object to become landable. Ideally, if you could share what the .gltf file xml lines look like for an object that works.

Interesting, since FS2020 does not feature helicopters, we don't know if the default photogrammetry areas have a landable surface? But cars drive over photogrammetry so I presume the road is enabled.

And I wonder if these parameters can be manually edited in some XML.
