Help! Zbrush Tileable Texture Seam...

gavinneil

Hi guys bit stuck at the moment.

I am trying to make some nice tileable textures in zbrush but keep coming unstuck when i bring my texture back into photoshop and notice a seam when i check the tile via offset.

So; how do i get rid of this? is there something in my process am not doing.

I am using the latest zbrush 4 fully licensed;

The process

0. Tileable displacement map
1. applied to polyplane (poly mesh 3d) 6 subdivisions.
2. Import texture (bmp)clone into texture map.
3. mask settings click mask by intensity.
4. In deformation > offset click on z axis click off x and y
5. type in -1 into the offset dialogue box
6. damnnn, nice texture
7. render
8. document export bmp or psd
9. photoshop
10 Anger...

so what am i failing to pick up on? proper frustrating as the workflow is pretty quick but with these seams it just falls down.

Help!

You guys will have the answers, thanks in advance

It's not a chatroom man, you could wait more than 19 minutes before bumping :P

Have you tried tiling the document in zbrush to make sure you're even dealing with something that is seamless? (And to make sure the document resolution is 1:1 so that the plane perfectly fits it when you're exporting)

You need to show some pictures of your problem.

Do like cryid said and make sure you map actually tiles (use ~ to pan around).

Else if it's a very small seam, it might be the zbrush render settings, I seem to remember needing to check the "best" render settings to avoid a small seam, but that was in zbrush 3.1, haven't used that workflow for awhile now.

I'll double check and upload some images, best render definitely doesn't fix this unfortunately.

So I checked the tile by dropping to canvas and using the (~) seems fine, no seams. So it's to do with the export process. I am rendering it on best settings (whether i need to modify the lighting or shadows or something i don't know) then hitting document >export .. If there is a better way of doing this please tell.

Cheers guys

It's going to be hard to tell without seeing the full document as displayed in zbrush vs the result. If you're changing the lighting or shadows I would think that could even throw off the pattern unless it is surrounded by other identical planes in order to make sure it is getting the correct shadow information cast onto its edges?

Irreal

is it a big seam or is it a mini seam?

What about trying a GrabDoc in the texture palette? (Making sure the document is 1024x1024 or whatever you desire)

Did anyone find out how to fix this 'border-on-the-document' problem? Because I'm having the same problem where the edge of my fully tileable ZBrush texture turns black when saving to a texture.
