Coming back to the actual Conversation:

After taking a closer look at the pre announcement of Poser 13 and the notice that Unimesh will not come at the launch of P13, I was wondering if the cause might be all the changes made on Poser since PP11.2 . My self already producing Single skin ( Unimesh figures ) with no trouble since about 2016  that work perfectly in Poser, this could be the main issue that is preventing them making that start up release. Concluding that I tried making these figures in Poser 12 and there sure came up some issues due the removal of certain Poser functions. So could say ( Stuck in the PP11 universe for this amazing feature ) Sometimes upgrades can also cause a loss of something that was consistent,  it was not commonly used causing the function not to work properly any more.

The function made by SM for Poser to be able to communicate in a better way with external 3D Programms witch actually is a Import export function for single skin models it might have been overseen and broken after all these upgrades, all was rather concentrated on the render engine, material room and store integration instead of being concentrated on rigged figure creations upgrades.

Allot of times Upgrades can cause also more damage then it could be doing any good.

Sure, users ask for Improvements, upgrades for there habits and what they are using the Program for, but sometimes they just overlook that it is already there, already a part of the program just not as a simple button.
