Maybe I need to break this problem down a little. 1. I need to know how to build a 2d particle grid in the first place... if there's a simple tut out there I'd love to do it.
2. Determine how to center and then align the grid to a surface . I'm already doing this with a raycast method for the Y alignment but I'm having to manually center and size the 3d grid to the surfaces bounding box using it's own built in controls... it's a pita when you have a lot of fields. I'm a smart guy, I should be able to do this if I can just get access to the proper tutorials or advice :-) It's fun regardless, I enjoy putting all the pieces together as I build them. FYI, basically I'm making corn rows in a field and I'm being passed geo for each field. I need to emit and rotate a grid on it as a base for instancing. Everything else I can do easily, i.e. all the usual scattering stuff, randomization of everything really.
