A good way to draw a lot of lines (3d grid)?
Hello,
I am working on a grid system for RTS-type game (practicing Unity) and looking for a good way to draw grid over terrain.
Right now i got a generic list of TerrainGrid objects with four Vector3's and a AllowBuilding boolean that is calculated procedurally accounting slope etc.
I need to draw a grid between those 4 points, grid color (green/red) depends on AllowBuilding boolean.
There is a lot of TerrainGrid (10k+) objects in that list, since grid size is 5-20 units and terrain is 1000x1000+
Right now i test it with Debug.DrawLine, but it is of course slow.
I thought about creating and pooling a bunch of LineRenderers, and enabling them when player is trying to build something, but today i found a hint that LineRenderer is not very suitable for this task and will be slow.
I do not want to mess with GL unless i do not have any other options.
Any advices?
If a commercial asset is a possibility for you, I can highly recommend Vectrosity.

And, just to be clear, I have no affiliation with the asset - I'm just a satisfied customer.
Isnt Vectrosity a bit overkill for just drawing some straight lines?
If youre able to make the grid already, have you tried setting up projectors?

heres an image of someone doing what it sounds like you want except with a hexgrid
