Hi guys!
I have experienced some strage triangulation in the sketchup geometry when I apply a displacement map.
I´m trying to do some grass and im freaking out .
Apreciate some advice to solve this problem!!!

What are your mesh subdivision settings for this material?

Hi Whaat!
The max mesh sudivisions are set to 10, but I´ve tried other values and the problem persists.

SubD of 10 is incredibly high
Using a displacement map for grass can look okay at such levels but would require a high amount of geometry to look okay (which subD should give)
For grass you'll be much better off modeling a simple blade of grass, making a clump with it, then using instancing to duplicate it. Godzilla has an amazing image over at the simple rendering thread in Works In Progress forum. (I would like but I forget which page)

Hi FiveAG!

The grass was made whith sketchup fur.
