Hello,
I am new to displacement map and today I wanted to try it out, so i created a model in zbrush, did the uv and all the stuff to get a good displacement map, now inside maya I import my low poly model and add a AiStandarSurface shader to the model then plug a file to the disp mat, switch to catclark and enable auto bump.
And now when I render my mesh, it look fat, so i tweaked a few thing and found out that when I tweak the scale on the displacement Shader it reduce the fatness of the model, but also make the detail drop at the same time, so i ended up with nothing in result…
Here is 2 pictures with the scale at 1 and scale at 0.
Hope we can find a solution for this, it may be completely stupid but I’ve been stuck on this for a few hours now and can’t figure it out even with lots of google searches…
Thanks you !
I have attached a zipped folder if you want to try the geo and map by yourself.

Hi!
I can't open this rar file.
Make sure to set mid color and Color Space correct.
Color range (-1 to 1 / black) or (0 to 1 / grey)?!
Color Space for file node maybe "RAW"?!
Hello,
Tanks for the answer, yeah i think I am right on the color space of the file node, mine is set to RAW, and my color range is grey.
i have reattached a zip file this time wish contain the mesh and map, it should be good this time.
Thanks you !
Hi!
You need to shift your color value by 0.5, cause this is your midpoint.
There are many ways to accomplish this, you may use one of the utility nodes.
Thanks for the clarification, but can you go a bit more in depth about that solution ? I d'ont have the best experience with the hypershade atm, and i would not know how to do it... sorry for my low knowledge about this, it may sound stupid to you.
Thanks a lot for the help !
Hey,
found my issue,
it was from zbrush since the beginning, the thing was :
my midpoint on the multimap export tool was set to 0.5 and arnold need it to be set at 0 to understand the value from black to white correctly, since i don't find the way to adjust my midpoint in the hypershade of maya i directly exported a new map from zbrush with the midpoint at 0 and it worked perfectly well.
thanks for everyone who helped ! hope this can help other ppl.
