Hi,

I want to automate export of preview png, but Spine rise exception.

Here is my settings file png.json:

{
"class": "png",
"exportType": "Frame",
"animation": "None",
"skin": "Current",
"images":"true"
}

Command line:

C:\Users\saffran\Google Drive\Animations\Spine\ScriptTest\scripts>"C:\Program Fi
les (x86)\Spine\Spine.com" 

---

input "C:\Users\saffran\Google Drive\Animations\Spi
ne\ScriptTest\scripts\png_2.json"  

---

output "C:\Users\saffran\Google Drive\Anima
tions\Spine\ScriptTest\Bear\generated-preview" 

---

export "C:\Users\saffran\Google
 Drive\Animations\Spine\ScriptTest\scripts\png.json"
Spine Launcher 3.6.49
Windows 7 Ultimate x86 6.1

What I'm doing wrong?
Thanks!

I just used binary.json from examples folder as sample for my png.json. Could you please describe how to create export JSON with PNG settings. When I do export as PNG, only *.png image created. Thanks
