Using Bas Relief

Here are instructions for using Bas Relief.

Make a scene with the various objects you would like in the scene to view from the camera perspective press numpad 0 to come back to 3d mode press zero again this is basic scene making in blender. Adjust the camera angle and object angles to what you would like the camera to see.

Switch rendering to CAM. In bas relief >Image Source select Viewer Node. Image Target > cube (name of target without extension)

Switch back to cycles render, show a 3D Viewport, click on Add > Mesh > Plane.
Switch to Edit Mode. Click on Edge>Subdivide 8 times. Switch back to Object Mode.
Click on Texture make a new texture and select image and open the file (an image file with an extension .exr)

Click on modifier > Add Modifier > Deform > Displace. Select the new texture created in step 11.
Choose the desired strength or in dimensions change the Z to the desired size. A good place to start is 15mm for Z.
If you find the edges are too aliased (staircase) go back to edit mode like step 10 and subdivide again. Repeat until satisfied.
Apply the displacement modifier.
Keep in mind that subdividing the plane several times can generate millions of triangles.
