Quote - @XFX3D: I know, I use Quickmat to write my mats and it takes care of these things. I've enclosed some tips for P4/PP users with my upcoming product users about how to make use of it - anyway, as this product produces real looking cloth surfaces with displacements and such the result will be poor regarding the original. So I will not tell anything like "P4 and upwards".

Yup, and those displacements are somehting P4 can't do (unless you render in some other app), which makes it perfectly reasonable to make those P5 and above. The fact that you try to give as much P4 support as you can should be applauded (and is, by me)!

I'm the asshole. You wanna be a shit? You gotta go through ME.
