Hi guys! Since my name has been mentioned, I thought I'd jump in here for my 2 cents worth. I hope Dr. Geep understands that I admire most of his work and acknowledge his significant contribution to the Poser community. However, in the matter of Poser Scale Units for Poser 4 AND for Poser 5, Dr. Geep is just wrong, Wrong, WRONG. He uses circular logic and mathematical mumbo-jumbo to obfuscate the issue, and he seems unwilling to consider even VALID proof which contradicts his pet theory. Furthermore, he claims that CL has somehow verified his theory, but my sources at both Cl and Egisys have verified that the scale in Poser has NOT changed since the introduction of Poser3 and has remained consistent in Poser4 and Poser5!. (although there is a bug in the P5 scale-translation process which I will describe below). The FACT is that the definition of one Poser Unit is no different in P5 than in P4. PROOF: If there were a difference in scale between Poser 4 and Poser 5 then EITHER the P4 male figure loaded into Poser 5 from your Poser4 runtime would be a different size than the Poser 4 male shipped with Poser5 OR the meshes and/or the Cr2 scaling would HAVE TO BE DIFFERENT. THEY ARE NOT. FACT: the scale unit is the SAME in Poser5 as it is in Poser4. Anything which suggests otherwise is just B.S. IMPARTIAL PROOF of the value of One Poser Unit - In my previous posts on this topic, I used Poser 5 as a reference, never thinking that someone might be silly enough to suggest that the scale in P5 were different from P4 - because it isn't. Fortunately, we don't need P5 to proove the value of One Poser Unit. Below is a proof that anyone can do using ONLY Poser4 and a 3D modeling app, so we can eliminate the issue of "different scales in P5". Note: In order to perform this test you must have a 3D modeling program that can work in a PRECISE scale using UNITS = 1 inch. Below I explain how to set up 3DS MAX for modeling in inches, and then offer the proof after that. Other programs use different standard units (the C4D standard unit is 1 meter for example) but they all can be changed to inches. Note2: Poser5 has a BUG in its unit translation calculations so to avoid this bug, you must launch P5 with units set to "Poser Standard Unit". Once launched, you may switch between units, and P5 will calculate them correctly. BUT if you launch P5 with units set to anything other that Poser Units, the calculations when switching units will be INCORRECT. This is perhaps where some people get confused about units in P5 because at times they can appear to be inconsistent. Use this workaround and everything will be fine. Fortunately in the proof below we do not need Poser5. On to the IMPARTIAL PROOF...
