That will be so sweet. I can see the priority. Probably a lot of "Poser doesn't/can't do X" has to do with that.
Is there a line for that beta?
I could make a reasonably long list of things Poser has to loose for not supporting unimesh internally, but since that is by now often called "the old problem", it suffices to say that Poser is not competitive in this market without that bare minimum requirement. As opposed to what some may claim, this is not a "bug", but instead a design flaw due to the time period when Poser was created, when unimesh was not a thing. So much that to this day, Autodesk 3DSMAX and Maya still don't support unimesh - and consider they are industry leaders in the 3D market. It comes to me as a surprise that Poser will overcome this before Autodesk does.
The first thing that comes to mind is Poser integration with Reallusion CC3 and iClone, which DS already had for years, but Poser was dead in the water because that would require unimesh support. Since Poser 9, the content creation tools were already reaching their limits without unimesh support, and in version 10 it has reached a critical point of no return, were some content creators just gave up on it and moved on elsewhere. Some cumbersome workarounds were introduced just before SMS gave up on Poser, but Rendo wants to put an end to this nightmare and fix this design flaw right now - before any more effort is put into mending and patching this mess.
This means redesigning how Poser works internally, which leads to rewriting the core from scratch. All the "Room" tabs in Poser will be affected by this, which means everything else needs to be redesigned as well. This is why all other companies who have owned Poser this far never wanted to touch this. It's too much responsibility, and a huge technical task - nothing to be taken lightly. Last time I talked to Larry Weinberg (original Poser's creator), he said he wanted to do this in Poser 12, but his team was disbanded while still in the times of SMSI's version 11, so it was never put into practice.
The good news came from a Bondware announcement made last month, when they claim Poser unimesh will have a working version "sooner than we expect", likely meaning still this year. The dev team is likely to be working in 2 Poser versions concurrently, since Poser 12 keeps getting periodic updates, and the unimesh Poser is still being worked on as we speak.
Since unimesh Poser means rewriting nearly EVERYTHING, I believe this will be implemented in stages over time, and not everything at once. Chances are that we might see a partially unimesh Poser release still this year, with incremental updates until everything becomes unimesh. I am guessing here, but having worked in the software development industry for years, this is a reasonable assumption.
To put things in perspective, I believe Poser simply has no future trying to compete in this market without internal unimesh support, where Bondware was the FIRST company to own Poser in the last 20 years who decided to face this challenge head on. Even though I believe most Poser users don't even know what unimesh is, everybody will directly or indirectly benefit from Poser finally becoming more competitive in this market. It's an exciting time to be a Poser user and content creator.
