Cities: Skylines (Steam) - Asset edtior breaks displaying of props when adding subbuildings (solved)

[Nickayz]

Describe your issue
Asset edtior breaks displaying of props when adding subbuildings

What is your game version?
1.15.0-f7

What expansions do you have installed?


What mods are you using?
None

Please explain your issue is in as much detail as possible.
I created an asset - a train station - last week before the update. It contains props and two subbuildings. When I load it now in the asset editor, the props are not visible anymore, but still counted. When I save it again, the props are not shown in the game anymore. When I don't use subbuildings, the props are being shown. The old version from before the update also displays props in the game.
So this means that after the update props disappear from train stations when I add a subbuilding.

Thank you for your help!


(The attached screenshot shows the train station with two subbuildings and with 38 props that do not show up on the platform anymore.)

Can you replicate the issue? If yes, please explain how you did it.
Yes. See above. I tried it several times with loading the old working asset and creating a new asset.

Probably best to attach here the asset files, and an affected save game file. Thanks.

Thank you for your reply, @AndrewT
Can you please do the following? That's easier (also for you):
Here is my new asset on the workshop: https://steamcommunity.com/sharedfiles/filedetails/?id=2866302352
Open it in any savegame or a new game - you will see props on the platforms. I created this asset before the update - so with game and editor version 1.14.
Close the game and open it in the asset editor - you won't see any props anymore. There is a collision problem with props when adding subbuildings. Other creators confirmed this problem - you can see the issue in ModTools, too. On the screenshots you can clearly see that the collision occurs between the main mesh and the subbuilding. And also with an older station (https://steamcommunity.com/sharedfiles/filedetails/?id=2521445882).
With this problem, I can't make changes to existing assets or create new ones with subbuildings.

Subbuildings should not overlap the main building or each other, in cases where you need two meshes to overlap the same area it's best to use submeshes instead of subbuildings. In the case of partially overlapping footprints I recommend you make the footprint of one of the buildings smaller, so there is no need for them to overlap, that should solve the issue of disappearing props.

Thank you for your reply, Avanya. Unfortunately that doesn't help me. I have created many assets for the game the past few years with overlapping subbuilings, e.g.: https://steamcommunity.com/sharedfiles/filedetails/?id=2657964937 or https://steamcommunity.com/sharedfiles/filedetails/?id=2285826804. There are two reasons why I need subbuilings:
1. More props for realism
2. I can't attach light props to a submesh. I have to attach light props to a roof, which is a subbuilding.
Why are overlapping subbuildings a problem? My assets have been working fine for years. It also gives more possibilities.

In this particular asset I need the roof as a subbuiling for lights. (Even more for the other assets with higher roofs.) And I can't make a smaller footprint of either the main mesh nor the subbuiling because they need props and pedestrian paths on the whole footprint area of 16x8.

I will add my solution as a reply, because this can be found by search engines and it might help others with the same issue.
Ronyx helped me with the solution. It seems that the bug is not new, but I haven't had it yet.

So you just have to change m_collisionHeight to 0. This goes for all subbuildings. Then save the asset et voilà:
