I need to create a height-map and pass it into a custom shader in Unity3D.
I can pass it into the shader as a greyscale texture.
I believe I can create a height-map in Blender by starting out with a 100x100 (say) grid, restricting movement to only the vertical axis, then I can use stock tools to mould the surface.
But now is there any tool that can export the resultant height-map as a greyscale texture?
Would I have to write my own using Python?
