Mudbox gives the correct range of the displacement Map after rendering which can be used in Max2010 etc.
What information does ZB give after rendering, or if not, apart from trial and error -
What is the process for Zbrush to 3ds Max 2010 to calculate the correct Displacement Length and Displacement Strength for a 16 bit rendered displacement.
Speaking from experiences and FWIW: Mudbox, Max, and Maya are all owned by the same company, so this is not surprising. However, there is no industry-agreed upon interpretation of displacement (or normal, for that matter) maps, including how to maximize the dynamic range of displacement map.
Perhaps ZB could add in some future pipline some calculation based on some specific render engine, but inevitably that calculation would work for other render engines, or even for subsequent generations of render engines from the same company. Given the wide variation between max, modo, c4d, renderman, maxwell, etc. in interpreting MPD (e.g. displacement maps) it may be a fool’s errend for ZB to put a lot of effort into this given that range of trial and error is pretty easily nailed down in a couple of test renders.
