ShaderSpider has been completely rewritten, and users will see many benefits, including faster material-copying and MAT pose saving. The new build is PC/Mac hybrid, and ShaderSpider Mac has been discontinued as a result.
Existing ShaderSpider and ShaderSpider Mac users can get the update by reseting the download from their DAZ Account page.
What was going to be an incremental patch ended up having so many new features that it's become ShaderSpider 1.5! You must have ShaderSpider or ShaderSpider Mac installed before updating; the new ShaderSpider LE 1.5 will be posted soon.
ShaderSpider is currently available for Mac and PC from DAZ. This update is free to current and new users.
A bonus toolkit for ShaderSpider and the 2nd Face Wow System is now available. The toolkit contains an SS6 preset that will work with all second faces you generate, a wacro that grabs material settings from the wearer of the second face, and a Python script that can be run to bind all of the wearer's morphs to the second face.
