Dave, here is an tileable alpha mask for the grating I was trying to make using both transparency and displacement. I could get the transparency to work but not the displacement.
Could you use this and make a camtasia vid on how to create a grill using this alpha plus displacement please. I will add it to my HOWTO library for when I might need it again and of course will have totally forgotten how to make it work. lol
Thanks!
