Specific Z-Depth Distance range

[kommando_2k]

Request: Z-depth rendering setting : specific Orthographic Camera distance range is need for creating 2d displacement texture. So the setting is "minimum" and "maximum" range for example the camera and object distance are 8 so the minimum setting is 6.5 and maximum setting is 8.5 to bring the object or plane white to black in a specific distance in render. It works with normal ugly slow mental ray but has fatal crash when rendering high 8k res.
Example:



Unfortunately octane render doesn't have the specific z-depth it's just default from camera to various distances.
Here is my work photoscanned with extracted z-depth to make 2d texture.
