I wanted my game to be like wherever any player goes it creates terrain (Blocky Terrain like in Minecraft)
But I don’t know how to do chunk rendering. Anyone please help me. And I am new to this place, If I am wrong please tell me.
There is a reddit thread on how to implement chunk loading: https://www.reddit.com/r/gamedev/comments/1tbsub/how_to_create_a_chunk_loading_system/. You are not necessarily bound to chunk loading. You can also find the coordinates of the cells that you want to have loaded.
I would try to start off with rendering some flat planes as chunks to keep things simple and ensure that your chunk loading works. Also, try to steal some code here and there. This has surely been done before on Roblox.
