Ok, I didn’t really know how best to explain my question in the title so let me explain it a bit better now.
What I want to do is have a grid that has all the verts at a set level (easy, Add > Grid > 10x10).
Then I would like to be able to manipulate the grid by moving the verts up and down (again, easy)
The trick is that I want the verts to snap to predefined heights. I would like to be able to have the verts only be at integer multiples of a height that I have specified, ie;
0h, h, 2h, 3h, …, 253h, 254h, 255h.
I want to make an 8-bit heightmap and would like total control over the verts and photoshop just ain’t cutting it lol.
Is it possible to do what I want?
I got how to export a heightmap from here;
but it doesn’t go into detail about how the heights get translated into gray-scale values, I don’t want to find that I put some verts too close together and they get converted to the same value when they should be one apart.
