Zbrush and Maya

acron

Hi guys, I'm not sure if this is the right forum to post to, but I need some help with Zbrush to Maya transfers
I am making some weapons for a indie game and I have the details nicely sculpted in Zbrush. In Maya I properly arranged the UVs and normals before I exported to zbrush.
The problem is that when I try to apply the zbrush normal maps, there is those ugly black edges on the maya low poly model.
I've tried exporting zbrush normal maps and applying, as well as Maya transfer map baking.

Can anyone help me out? Thanks

i need an image of the problem

Yep a screenshot would be helpful - just out of curiosity have you tried Xnormal? Its a nicer workflow than having to import the low poly into ZB and bake (imo anyway.)

Post image of the zbrush sculpt, maya low poly, and also of both of them on top of each other Also helps if you show the UV layout too.

A few things I would check - bake the normal using xnormal. make sure you have padding in your normal map when baking. also make sure your vert normals are set correctly (hard edges at UV boundaries, UV boundaries at hard edges). make sure you have bleed in your normal bake, and don't use black and the background image color.

I tried tweeking Maya's Bump depth setting, it seems to help a bit, but then I lose the details

What res are you baking at?

Is the bump map node thing set to tangent space normals by any chance :P

Steve Schulze

I'd guess it's set to "bump map". That's what usually gets you an ugly pixelated result like that.

Either way, switch it to "tangent space"

Thirded on checking your bump2D node settings. Also, if you mean 'Maya Software' by 'Maya Render', try switching to Mental Ray or better yet, viewport 2.0. The Maya Software renderer is shit at rendering normal maps.

The only other suggestion I'd offer is that your UV's may be way too small if its giving that result, but I imagine its as the others have stated about the bump2dnode.
