I had an opening XGen error as same as this site had. I'm using MtoA3.1.1
I had the exactly same issue. After I reset and changed preference, I could not open up XGen.
this post said Arnold was fine about this issue, but It happened to me.
You could not open up XGen? That doesn't sound like a rendering problem. Probably the xgen plugin is not loaded.
As for the original problem, you have to export patches for batch render.
When I rested preference and open up a Xgen shot, xgen could not be opened up. Xgen was uploaded, and there is no XGen description. In outline, There is XGen, but it could not be shown up. Even in Arnold Render View, XGen did not be shown up.
I had had a same preference before I reseted preference, so I just used the same preference, then it worked.
I just am using the previous preference which means I could not find solution about that problem.
if you can help me out, I will try reset preference and test if it works
Open the Plugin Manager. Is the xgen plugin loaded?
The problem was gone. I just imported XGen Collection which is created automatically when shot is saved and right below the shot in a folder.
It doesn't seem to work at the first time. I had a another issue when I imported XGen collection.
However, I just tried to save and close the shot and open up several times, then it worked. I don't know what cause the problem and how It worked.
Thanks Stephen Blair for helping me out
