I want to place the objects on the floor immediately after the planes generation (i.e. Without tapping on the screen I want to place the objects on the floor immediately after the planes generation).
Can anyone please help me or share some of the references for these issues?
Maybe just send the placement raycast every second or something in a coroutine and keep going until it is placed?
Otherwise you have to look into the code from lightship, which can be complex
Can you please take a look at the Advanced Meshing: Garden Chunks tutorial? In this tutorial, Garden mesh generates automatically based on viable surfaces within a specified tolerance. You need to start with the Meshing Tutorial: Getting Started as a prerequisite.
Hopefully, the above information helps, and please let us know how it works for you.
