I try to re install the plugin version 1.7 and everything goes OK.
In fact as you could see from the MXCL consolle it read the right MXS file inside a macintosh HD and "scena_Walter" folder.. as it is and as I set with the maxwell render settings TAG inside cinema...
if you could see from the past imagine that i post, the 18.104.22.168 plugin version write a wrong path for the MXS file... could you see the double slash "//" from the MXCL consolle?
That's wrong cause the MXS file is inside macintosh HD and the "scena_Walter" subfolder... and inside cinema with the scene TAG I set the right path.. the error is caused when cinemaxwell write the MXS and start MXCL..
I attach the 1.7 plugin consolle version!!!
I hope that now is clear and someone could help me please!!!!
