HELP - I can't make my displacement map work at all in Arnold.

[Anonymous]

Hello everybody

I have one problem and one question:

My problem: I spent the last 3 hours looking for a solution, I tried a lot of things but I still couldn't find a way to make my displacement  map work at all. The details don't show up in my model. I already tried .png and  .tx formats, and nothing happens!  My map was generate in Substance Painter and it's working perfectly in Mari.

Is there something wrong with my nodes?  What am I missing?

This is my mesh with the displacement map

my nodes:

My question is: Where do I plug my cavity map?

 Thanks in advance for any help!

you need to add subdivisions to your mesh shape and use 16bit or 32bit maps(.exr format on Painter) for you displacements. Another important thing is to change to raw the displacement colorspace, anw, follow the Arnold help and should be ok

I found a solution, after suffering more than 2 weeks with it, 
Use the Substance Plugin on Maya to create a shader through multimap uploading, upload your Displacement Map, on the Height section ... thank me later
