ShadowBox Texture (Back, Bottom, Right) from #AskZbrush video?

[apd_fan]

Very new to Zbrush.

In this video https://www.youtube.com/watch?v=0bvO5dd2woQ (4min 30s) there is a PNG with a grid and Back, Bottom, Right on it.

This texture is also displayed on the main shadowbox site: (In the “Using References” section)
http://docs.pixologic.com/user-guide/3d-modeling/modeling-basics/creating-meshes/shadowbox/

Where can I download this texture? Or is it installed with Zbrush?

Thanks.

It’s already installed in ZBrush. It’s in “ZBrush 4R8/ZTools/Shadowbox” folder and it’s called “SBRef.PSD”.
