Blender 2.8, cycles I'm trying to get a height map from a mesh. The tute I am following is here: https://www.youtube.com/watch?v=ekogw2Zm20Y
I have two meshes in scene, a grid (flat) and a 3D mesh. I have a couple cameras in scene and a sun lightsource.
In the viewport I can see the object with material color assigned to it. My camera is above the object. Camera view shows the object. Camera is set to orthographic.
When I render (Render > Render Image), I get a grey screen. What am I doing wrong that my render looks nothing like my view port, and how do I make things so the render shows what I see in the view port?
Willing to share blend file as it's just a test, but I probably don't have enough rep for that.
Thx
