@bobbystahr
Thanks for the tip, very handy
Dune is right though, I want the data automatically.
My workflow involves going between TG and external apps. I use the data specifically so that I can locate and replace procedural terrains with displacement maps which is based on geometry.
Currently I get the bounding box info from an external app and punch that into the shader/camera etc in TG.
Usually I need the numbers to be accurate. However on occasion using the technique bobbystahr mentioned will work.
I suppose if I start the process in TG, then I would already have the data I want, on the other hand I'm not always working in such a linear fashion but its a nice idea
Cheers
