Can you provide the raw PNG used to make this Perspective brush? My main paint software (Clip Studio Paint) does not import .abr so I tried loading this brush into Gimp to export the PNG but it doesn't load there either. If you can provide the PNG I will make a CSP brush and post it here in case others can use it. I do not have Photoshop so I cannot export the PNG myself. CSP has very nice built in support for creating perspective rulers, but I can see a use for having this brush too, its much faster than setting up rulers in CSP.
