That looks correct, but change "industry_floor.lua" to "none.lua" so that nothing shows up.

There should also be another section either right above or below this one that says terrainAlignmentLists.

You should make it say this:


result.terrainAlignnentLists = { {
type = "EQUAL",
faces = { }
} }

With that changed, we should be able to place these markers on tracks underground without issues.

result.groundFaces = {}
result.groundFaces[1] = {
face = {{0.01, -0.01}, {0.01, 0.01}, {-0.01, 0.01}, {-0.01, -0.01}},
modes = {{
type = "FILL",
key = "industry_floor.lua"
}}
}

return result

This is what I have right now in mod, is it the same what you suggested?

Ah yes you are correct, however collision can be disabled while still retaining the attributes needed for configurable constructions. You only need a very small ground texture to make an asset do this (something small like 0.1 unit for X Y and Z). It doesn't need terrain alignment. That should fix the issue with underground placement. There are many asset mods that do this.

I'm not sure this can be done. As far as i remember it allows it to be reconfigureable construction, which is a key mechanic

Do you think you could remove the terrain alignment on the markers that can be placed? It restricts them from being usable in tunnels. Thanks!

Anyone can add compatibility to any loco.
Furthermore, in mod files I've left guide how to add support for any loco you want.
And generally I'm hoping that other people or mod creators will add support for a locos they want. Because it's impossible for me to cover everything in the game.
As a test, as a first step, I added support for one freight, one passenger loco and the MU, to cover every type. And these are Ukrainian trains just because I can use them on my Ukrainian styled map.
But once again anyone can add support for anything.

Is like only russian loco compatible? Do creator or you have to make compatible?

Thanks

Sorry, I don't understand your question.
But I guess you should just install this and some vpc compatible loco and try it.
Or please rephrase your question.
Or read again through mod description carefully, maybe it has answer already

How loco specific will it be? Will it include one for every loco you have in the game or do you gave to add one per loco into the mod?

absolutely fantastic

This is a feature that train enthusiasts will love!
I'll admit, I'm not that knowledgeable about trains, but reading the description makes it sound fun! I'll trust you, recognize that it's a train, and enjoy it.
Thank you, I'm taking another step into the world of railways.
