Hello!

I have just finished detailing a model in Zbrush (which is first modelled in maya), and now I am up to the stage of importing the displacement map to maya for render.

I cant seem to work the 'multiple displace 3' function (zbrush 3.1), so i just used the 'create displacement' function. Although, when I try and import the resulting tiff file into maya, it says 'failed to read file...'

I have tried resaving it from photoshop as a 32-bit float file, but still no luck. I heard there was a way to convert it to .map with the imf_copy exe in the maya folder, but I dont know how to use it...But still, I should just be able to use a tiff, right?

And I wasnt sure if it was exporting from Zbrush at 32-bit..(my exported file is very grey, only when messing with the levels a lot do I find the detail that I painted...) Is there any way to make sure of this?

I just want to start playing with this displacement!!!

any help would be great...

thanks

Well, I managed to get it working using the multiple displace 3 function. I got a tiff out of that, then converted it to a .map file with the converter.bat file. (This is the bit that cleared me over the hurdle!)

So now, I have a displacement that is rendering in maya, but it is displacing pretty badly on my model (breaking it up, extruding odd bits etc)...

So, any info anyone can give me on fixing that shit up would be great!

Theres probably 100 threads regarding these issues.


Search for "catmull-clark", which should give you some additional info bugs in maya 2008, which might solve the displacementproblems on textureseams. And seach for "zbrush to maya pipeline". Scott Spencer has written (and updated) a great tutorial covering those steps. (the catmull clark subdivision bug was solved by scott spencer aswell). Theres even a huge thread over at zbrushcentral.com regarding that. (aswell as instructions for multi displacement 3).

Mental ray is picky about which formats it takes. Personally I dont like map files. Regular bmp files are great too. The displacement tab in zb generates greyscale maps, which mental ray will not accept.
