Hello
I had a problem when I tried to make a new project with the new unity, pm, and photon but you can avoid this.
The key is the sequence.
So to create a new playmaker + photon on to Unity5.2.2f1 follow this sequence:
- New empty project
- Import Playmaker from assetstore
- Import Ecosystem
- Import the Playmaker P U N (for Unity4, not for unity5) from the Ecosystem
- Import Photon worked demo if you want (not necessary)
If you use the "Playmaker P U N" for unity5 pack in the Ecosystem, you will got few error and you cant solve it!
You need to import the Playmaker P U N (for unity 4) and it will automatically import/update the unity 5 pack too but with this sequence you not will got errors.
