I’m trying to control the shutter of my epson using PJ link. 

Im using an EB-PU1008B 8500LM

Trying to get PJ link to work. I have the computer talking to the projector through the web control and that works. I have pinged the projector using the port and that is successful. 

There is no password on the PJ link.

Still nothing working from the projector.

What else should I try?

@woland hey - i dont know if the original link worked but uploaded the clip to youtube so you could see what it was. Not sure my previous upload worked at all.

I will do an update to this as i've since worked out aiming controls in a 3D environment so you can hit/miss a target

I could create a nice tool for creating polygon masks with blur, if it would be useful?
It would allow you to set the number of points to the polygon, and adjust the XY position for each (numerically, No nice UI). 
I would draw to an oversize canvas, apply blur, then crop to the actual canvas size (this should allow edge blur evenly without edge artifacts).
This would be a Pythoner based User Actor, and isn't what I would call a final solution to the issue, but I could have it done in a couple day max.
Would this be helpful to you?

And  I'll add in my set of Timecode Tools (user actors): TROIKATRONIX : ISADORA - DX – Timecode Tools

@dusx Jumping in here is say yes, I'm looking for the capability to draw complex masks (with feathering) please!
