When using LuaSurface.can_place_entity build smoke is visible, even if the entity cannot be placed.

Demo while checking to build a Rocket Silo over Solar Panel:

Can you provide the relevant code you are using?
Nothing like this has been reported before, so it is worth double checking the script is not at fault

Thanks for the report however I can't reproduce what you're saying. As Klonan said: can you please post an example mod showing the problem? I suspect it's some mod problem and not a game issue.

The relevant code can be found at: https://github.com/Roang-zero1/upgrade- ... #L203-L214

Maybe the build smoke comes from trying to fast replace a non fast-replaceable entity?

I have no access to the game right now so unfortunately I can't test any further.

Trying to fast-replace an entity would generate build smokes since it's: create entity -> try to fast-replace. Should the fast-replace fail and then you destroy the new entity you still created it so the smokes are created.

Yeah that was it, thanks.
Can be moved to not a bug.
