Texel Density

How can I view the Texel Desity ? any ideas? I want to know how streched the pixel are in a slop.?!
If the angel is to sharp the texel density will be bad.

Import a checkerboard texture and use the overlay node to overlay the texture on the heightmap. For steep slopes you can do 3Planar mapping if you’re using the result in a game engine though.

Thank you. I could use my macro and it worked out fine.
