I installed Poser 12 a day or two ago and it was working fine.

Yesterday I reset my firewall settings on my PC and that must've broken something in Poser. Now every time I do a render it will complete the render, but not save it, it wipes it and I get a blank screen.

I uninstalled and reinstalled Poser, but that didn't work.

Any ideas how I can fix this?

Here's the log:

The Firewall settings allow Poser access to both public and private networks.

So this is the problem:

When you save a file, Poser uses the location of the saved file to store the cache in so it can render the image.

When you're working with an unsaved file, Poser doesn't have a directory to store the cache in.

It defaults to Program Files\Poser - which is of course read only (I could see this in the queue manager).

The first time I installed Poser it created a directory under documents\poser\rendercache (something similar). But at some point it lost the connection to that folder and would no longer use it. When I deleted that folder (I wiped everything Poser) and reinstalled Poser, it didn't create the directory again - and so didn't have a valid path for the render cache.

This problem persists but I now have 2 work-arounds:

1. I can send it to the render queue where I can specify the output path

2. I can first save the file (oddly enough when I'm creating something I work with unsaved scenes 90% of the time because you're saving the props or materials - not the scene)

From what I've been able to check with Poser12: it uses as a base path this setting:

And from there, it'll create some sub folders in which it'll drop some files. Some of them seem to stay after filled (PoserTextureCache, cefcache, etc..) whereas others are empties once the render is over (PoserFFRencerCache)

Be sure that some valid path is set there. In my case, it's located on an SSD drive, as are all Poser's Runtimes, and executable directories, for example.

Oh and be sure that no f..cking anti-virus isn't interfering there

THANK YOU!  

It's Windows Security. And this issue was caused by the "Controlled Folder Access". 

If that's ticked on, Windows blocks Poser. I listed Poser as an exception - and now everything works.

So for anyone else having this problem, the steps are:

Settings - Window Security - Virus & Threat protection settings - manage settings - scroll down to Controlled Folder Access - Manage controlled folder access - allow an app through controlled folder access (And if you had this error, Poser will be listed as recently blocked apps - just select it.)

Oh... great 

Thank you for this disconcerting diagnosis: As yet, it is a mischief my paranoid Norton's has not perpetrated...

FWIW, setting up Win'10 so my network-render 'Box' played-nice with this CAD-Tower was frustrating, given the 'security' error messages were remarkably unhelpful...

Speaking of anti-virus programs: for the people that are using Win10/Win11 and rarely go online, at least only on secure website, with a good reputation, Windows own anti-virus is rather good, as it's deeply "inside" Windows. In my case, I've long used E.Sset + Malwarebytes. Now, I'm using Malwarebytes only.
