Hi there

I'm having issues with one roof material which has worked for me before but usually produces very strange results. It seems to be something to do with displacement maybe but I'm not sure how to fix it!

It's the roof tiled area on this image: https://www.dropbox.com/s/6a9x9jfgjqi2l ... t.jpg?dl=0

I dont think it has to do with the subdivision of the surface, as I have made a test with roof planes subdivided in various frequencies (using sandbox and other methods) ) and I am still getting a lot of displacement (?) Here's the test: https://www.dropbox.com/s/07tbc1pb0y97t ... t.jpg?dl=0

It's such a perfect material I really want to use it but it keeps causing problems! It's this material: http://resources.maxwellrender.com/sear ... earch=roof tile&v1=0&v2=0&tipo=

Thanks in advance!

The height value in the displacement of this material is set to 12%, have you tried changing it to use an absolute cm value, instead?
