After pushing OK, there is another dialogue box that says:
Error encountered while importing a file
I have spent a fair amount of time searching the internet for a solution to this problem but the only thing I can find is one thread located in the zbrushcentral archives. Which I am unable to access
I have made other objects that import correctly using GoZ and I can import the defective meshes using an obj export/import just fine. I am really wanting to use GoZ for this transfer because I have creased edges on these mesh's and am honestly not proficient enough with zbrush to apply creased edges to them inside of the software.
Same is happening to me, new machine with maya 2012 hotfix 4, and zbrush 4 r4.
Would love to be able to bring in a creased mesh. But I'm unable to import .ma files with or without GoZ. I was able to do so before with the same versions of maya and Zbrush on the old system. Confused of why it stopped working, I don't think is GOZ related for importing an individual .ma doesn't work. I've created a simple sphere in maya to import in Zbrush, same thing... Help!
excellent find. I just encountered the same error. Didn't find anything on vertex color, but I figured uv-data is also vertex data, and indeed; a second uv channel was the culprit. Removing that made a transfer to zbrush possible.
