Displacement Shader MtoA

Hi,

I am trying out displacement (Maya 2018 Arnold 5) and I have a simple test image (32bit Tiff). The results I get from the render look a bit so I guess I am missing something.

The render is attached and the hypershade set up. It is on a plane with a high polycount.

On the support notes it shows Subdivisions with iterations and adaptive metric etc. (image attached) but I can't find this setup in Maya or in Arnold so I am at a bit of a loss.

They are in the Arnold attributes of the mesh.

Be careful when increasing the number of iterations on a high poly mesh as it can generate a lot of polys.

Did you set the file texture to 'RAW'?

@Lee Griggs

thank you

yes the 32bit tif is set to raw. I still have an issue with this as it shows an odd render on the height (a shaded area that is not there). I set the scale down to 0.05 but not sure how to clean this up and make it sharper as per the example in the docs.

thank you again for the help (liked and rewarded)

Is the image being displayed 1:1 in the render view?

Can you share the scene?
