• 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.

MSFS Is there a way to make a model a solid surface to build on?

Does anyone know of a way to fully solidify a model so an airport can be built on top of it?

I've done an aircraft carrier mod which at the moment is just a lump of terraformed seabed with the model around it.

Obviously there's no way the terraforming can account for a ship's concave shape below the top deck so bits of it are sticking out and the sections of deck outside the terraformed area have no substance. The terraforming is also I right pain so I'd really like to be able to do away with it completely.

The model is exported from Blender with Blender2MSFS. Might there be a material setting in there to make the entire thing a solid object and the SDK will recognise it as a surface it will build on? Or is there any other method I can try?

I've seen the LatinVFR scenery with a landable carrier so they managed it. They may of course keep how it was done a secret.

No problem, what you are looking for is called Road Material!


Whether navigable bridge, helicopter platforms or aircraft carriers. Every surface can be made drivable or landable. There is a corresponding option in the material settings, you just have to check it:

I've tried ticking the road material in Blender. It made the texture white and it still wasn't available to build on when the model loaded.

Is there an obvious setting I'm missing? My 3D modelling knowledge is non existent pretty much but I have figured out basic things like making glass transparent before export. This might be too clever for me but I assumed it would be equally simple. Maybe not.

That looks like 3ds Max? I've no idea how to use that.

And do I select MSFS standard as the material mode and then select road surface?

That makes the surface white, and when I load the model it's still not solid and can't be built on. Edit - got the texture back but now it's flickering and checking road still seems to do nothing.

This is probably incredibly simple. It certainly isn't for me.

You have to assign the material to your surface polygon with the option "Road Material" selected! The material slot for the base color should contain the texture with which the surface polygon is mapped/textured.
 
I've selected all the surfaces that I need to be solid. I select MSFS standard and road material. The surfaces go white. I add the texture again. I make sure that's a road surface too. I export.

It's not solid. I don't understand this so I think I'll give up for now. Thanks for your help.

I tried the option in Blender's MSFS Material settings but the aircraft went through the platform with the Road Material. I had Collision also enabled but it was not landable for some reason

Then maybe something is wrong with the Blender Exporter !? Has anyone managed to export a drivable surface with road material from Blender?
 
I have use Christian's method for a motorway bridge and it works perfectly: the AI traffic can jump the bridge and no problem.
It has be done under Blender 2.83 and 2.91.
For a aircraft carrier:

Thanks, I use the 2.83.5 with MSFS Material Exporter 0.4. I assigned Road Material to a Bridge I did and my friend who tested the scenery told me he could land on it. Cars drove over it but were sinking a little. Good news.

But in your example I see that only flat invisible surfaces can have this? If we have an uneven platform, I suppose not possible to make it landable.

Hi.

The Road Material doesn't have to be invisible!

In my example with the Mintarder Bridge, the material is as follows:

Material type: standard
Double sided: check
Day Night Cycle: check
Road Material: check

All other settings are not affected.

The surface of your carrier, try to detach the surface from the overall model (detach). Otherwise there might be problems with a sub-mesh.

Great, thanks!
 
Hi,

I have created a carrier here
I have used MSFS Invisible Material + Road Material in order to have a runway. But, because I have checked Road Material , I have sometimes cars.
If I removed Road Material, I go through the runway...

Any idea to remove cars ?
 
I think the Road Material works here on any material and any surface now. No need to put invisible flat rectangle.

I did a quick test and the 3D objects (with uneven surfaces) I assigned Road Material to its textures are solid and landable.

Also, cars appear over these but sometimes sinking a bit (contact point maybe).

However if you go into Drone mode, or external Camera mode the cameras sink into these platforms.
