Is it possible to dictate where I insatll Poser 14 content? It seems when I install throught the Purchased Content it wants to put it on my c: drive. I want to install it on on another drive! Cheers

I haven't found any way to accomplish this through the purchase tab.  Either you let the software automatically install the content and you relocate it elsewhere, or you download the content and manually do the installation.

When you install Poser this should apply to Poser's 12-14, I know it works with 13 and 14 as I have done it at least 100 plus times in the past 4 years.  When you get the installer it will ask for where you want to place your Poser program. It will open up a dialog box and ask you to Select Destination Location and it will be prefilled with where to place the program.  The very first time it will probably say some like C:\Programs\Poser\*.* (it has been a very long time since I let it install to the C drive.  I normally tell it to install to E:\Poser\Poser 14 as that is what normally fills in after the very first install of a new version.  Since I never install over a prior version (saves time deleting) I just make sure Poser is shutdown and rename the Poser program folder something like ZPoser14_0_0148 (the current version that i am running) and let the installer place the new version in the Poser 14 folder which it creates since the old folder was renamed. One you have told it where to put the program then you get the choice of where to put the runtime.  The default is Shared documents directory.  You want the bottom one Other Location. Check that and on the next screen it will always come up with "C:\Users\Public\Documents\Poser 14 Content"  here you have to make sure not to click through or it will mess up your install.  Click the Browse button and it will bring up the picker choose the folder above where you want the content to go (in my case it is E:\Poser Content\) choose that it and it will fill in with "E:\Poser Content\Poser 14 Content".  Then click on through until the program installs.

As long as you don't save anything to the default Poser 14 runtime you can do this everyday and never worry about losing any content.

The added benefit is that you have a prior copy of the program that you can run by going into the renamed folder an double clicking the Poser progarm icon.

The other option that I use is Symbolic links.  What this does is point a folder to another folder.  This is very useful for Poser in that Poser creates a folder called Purchases inside the Poser 14 Content.  this is where Poser will download content to.  While nice in that fact it keeps it together it makes it hard to manage if you have Poser 11, 12, 13 and 14 since they all the same Purchase folder and it is separate from the others.  So I have made a Symbolic link to a single folder and placed the link inside each content folder so the program sees it as its own but they all share the same location so I don't down load the same content several times.

If you install the Poser 13 app AND all content AND direct the final renders to one or more HDDs instead of the Windows 11 boot SSD, does it slow down render speed? I have a 2TB SSD and was originally going to install Poser 13 (possibly on a separate partition) on this same drive the W11 OS. I DO have a fairly fast new PC build (Ryzen 9 7900X @5.7 Ghz with 24 threads, 64 GB DDR5 6000 RAM, and a GTX 3060 12 GB GPU) to contribute to fast rendering, but I'd hate for the HDDs to create a bottleneck if I decide to place ALL of Poser 13's app, content, and render output on one or more 7200 RPM HDDs.

I doubt it is going to make much if any difference in speed.  I have a Ryzen 9 5950X with 64 GB Ram and a GTX 1070 8GB for Video display and a RTX4060TI 8GB used for rendering.  Normally I just do test renders @ 1920x1080 using the 4060 and can get a decent looking image in about 5 seconds using Poser 14.  And when I do a 210 frame animation at the same settings it works out to about 3 seconds a frame that counts the time to save to disk.  The bigger speed facto is going to be have many Polygons your models have.  I just did a test with a Poser Sphere normally 2048 Polygons and that is quick.  However, the test I was doing was on displacement so I cranked the SubD level from 0 to 7.   That took the 2048 Polygon sphere up to 33,554,432 Polygons.  The longest time was waiting for the program to send all those Polys to the card.  Once there it zipped through in ~ 7seconds.  And all my programs and content are located on the slow HDD's.  So, I am not sure how much faster being on a SSD is going to be, but I doubt much.
