Answered: Exporting and normal map problem

ZBrush Usage Questions
#1

Am using Z brush 3.5 r3 and Maya 2010 and I’m new to zbrush.

First the Exporting one:

I imported a low poly model from maya to z brush with uv’s unwrapped.
I do my sculpting in zbrush and then I export it at a lower subdivision level to maya in the OBJ format. I open the OBJ in maya and I see no UV’s. Not just that but when I go the UV component mode of the model it doesn’t even show the UV points (it shows vertex, faces, edges but not uv’s).

Then I exported it as a .ma format from zbrush and when I open it in maya, it crashes.

I tried the .goz and maya says its an unrecognized format. i did the same thing with a simple sphere that I imported from maya and when I export it back to maya from z brush I get the same problem.
Maybe I’m missing something or exporting the wrong way.

It’s my very first model in zbrush and I’m stuck with this problem.
How to i fix this?

Now the normal map issue:

How do I increase the size of my normal map? It always creates a normal map of 2048 but when I change the setting in my texture pallet to 4096 and redo the normal map, it still shows a 2048 map.

How do I get it so the normal map is 4K or any other size?

The first thing to do is to upgrade to ZBrush 4. It’s a free upgrade. Submit a ticket at http://support.pixologic.com and provide your purchase information.

Ok so the UV problem is sort of fixed since I’m using ZBrush 4 now (should have done this earlier but oh well).
It’s just that there is this one thing:
If I only export an obj then is it a normal thing for the model to NOT have any UV’s when I open it in maya? Because this time I exported it with the texture button on and it gave me UV’s but without it the issue remains. I’m kinda confused.
Oh, and the .ma file no longer crashes maya and I get the Uv’s and all but I’m kinda confused about this OBJ thing. Isn’t obj supposed to have UV information?

But the normal map problem is still there. I’m able to generate a normal map and even export it but it always generates a 2k normal map. How do I change the size of the normal map it generates?
