... some Poser content creators provide indication of which figure the physical poses are for.  Hold your horses and please hear me out.

I have recently re-installed a multi-Gigabyte shedload of runtimes sorted by year of download.  Working backwards from the current year (2012, at this time), I hit upon that transition year of 2009.  That year was a time during which there was almost an equal amount of content I collected for the DAZ Generation 4 and Generation 3 figures.  

Where there is no longer a related online webpage, or where there is no readme.txt provided, I can check the PNGs supplied, or the filenames, or even directly inspect the texture maps to get a hint of which figure a MAT pose is for, as a last resort.  

However, in the case of a physical pose, I cannot tell whether it's for Victoria 3 or Victoria 4, for example, in the absence of any other clues.  Or can I ?  Opening up the PZ2 file in a text editor doesn't seem to provide any clues.

In your specific example, you can tell because Victoria 3 has buttock actors, and Victoria 4 does not. There are other distinguishing features you might use for other figures (Victoria 2 has an upper neck; G2 figures have a waist actor; and so on) but in general, there's no way of knowing after the fact.

Freebie creators who don't provide readmes are still generous and wonderful people. But I wish they wouldn't shoot themselves in the foot. :) 

Ah ha ! Thank you for the hints, EnglishBob.

Certainly, I am grateful to freebie creators.  Not at all slamming them; hope there is no misunderstanding.  

As I am not at all familiar with rigging and the innards of pose files, I had no way of knowing prior to this.  OK, off to inspect the text lines.

You may prefer to use a dedicated Poser file editor, such as CR2 Editor which is free from my utility page.

None at all. I put in my disclaimer to be clear that I wasn't slamming them either. Since I host the Poser Freebie Bitch 'n' Moan page, that would be extremely hypocritical of me. :)

Open the pose in a text file and look at about line number 8 for "targetFigure". If it is there it will tell you the name of the figure that the pose was originally created for.

@PhilC:

Thanks for that info as well.  I opened up some PZ2 files and did indeed see those text lines.  

BUT.

There are other PZ2 files which have something like this as opening lines, purely for example - and I am left without my last clue:

{

version
{
number 6
}

thighLength 0.15103

controlProp GoalCenterOfMass:5
{

rotateY yRotate

@EnglishBob:

I'll be swooping past your webpages as well.  Thank you for the information.

When all else fails, you can load several models, the ones you think it might be, and apply the pose. The model who looks the most normal is the one. This is a PITA though.

Those are pre-universal pose files so you are on your own I'm afraid.

Had the same problem. I was recently sorting through some older clothes and characters but was not sure if they went to Victoria 1 or P4 Fem. This helps a lot, thanks. ^ ^

@RedPhantom - I am really trying to avoid doing the trial-and-error route.  That's going to be such a pain, I agree.

@PhilC - so that's what kind they are: pre-Universal Pose PZ2s.  Got it.

Hmm. One would expect the thighLength parameter was to serve as an identifier of the figure. 

For V2 poses I find: thighLength = 0.177885

For V3 poses I find: thighLength = 0.17748

For V4 poses I find: thighLength = 0.188311

Checking co-ordinates for Victoria3:
rThigh centre = (0.042, 0.372, -0.008)
rShin centre = (0.035, 0.195, -0.019)
Using Pythagoras Rule: length is 0.17747958, rounded off 0.17748

So, when in doubt, check thighLength 

@bagaos - wow, I had no idea that was the case.  Interesting !  Thanks for this.

Of course it is vulnerable. If you touch the joint centres just a bit, the length and the result will be different. It works when poses are made with the 'right out of the box' character. Fortunately, most pose sets are.   

The actor names may be more decisive. Apart from the buttock actors mentioned before, differences there are found in the feet and in the head (jaw, teeth, tongue). Also some female characters have breast actors.
