Plug-ins TopazLabs do not work. I have an error message : 

"Can not Proceed - IPC Memory in use or Image size is too big for the system."

Is there a solution?

Hi Digigravure,


Could you please confirm how you installed the Topaz plugins? Did you follow the instructions from Affinity Photo's help?

Using Digigravure's suggestion for the 'Photoshop Plugins' tab dialogue in Preferences (8th August post), I have all of my Topaz plugins working apart from Re-mask 4. On launching Re-mask from Affinity Photo a warning message appears to say that the "transparency" needs to be unlocked. This happens whether the layer is locked or not.

My system is a rMBP running Mavericks.

Here is the solution for Mac.  First let me restate the error message so it will make it easier for others to find this answer:


"Cannot Proceed:  IPC Memory in use or image size is too big for the system."


In Affinity Photo, go to Preferences.

Choose Photoshop Plug-ins.  (I assume you already added the Topaz Plugins.  You should see them."

Near the bottom right, click the "Authorize Global" button.

You will have to restart Affinity.   (It will put a path of / that represents the root directory.)

Your Topaz plugins should work now.
