[Zbrush] Restricting brush directions.

cox

Hi guys,

Anyone know how to restrict Zbrush brushes axis directions as shown on this mudbox tutorial (1:15).

thanks.

Perhaps Transform: Modifiers will do the trick

dustinbrown:Thanks man! It will also help.
cryid: right in the bull’s eyes.

Sorry to Necro the thread but doing this breaks the use of alphas, Anyone know how to work around this? Thanks!

Tried this?

Works great from max if you start in Z and GOZ a plane from it to 3DS (I did a simpler plane and I divide it only with smoothing off thus not needing any "border" so I can save polys and have better resolution / subdivisions and my brush is more responsive).
you can extend the plane all the say you want so you can put alpha on it I guess (let me know). Be warned that wrap mode make sometimes zbrush slow down quite a lot.
Hope it helps!

Yeah, I've used this method in the past. I was hoping for something that wouldn't involve the wrap modes. It gets a bit heavy for my crappy computer at higher tri counts and the extra step of making sure I only get the middle is a bit annoying.

Something more streamline would be nice, I'll keep looking I guess, Thanks though .

I don't think there's any other way around it.

You can set up the central tile (the actual important bit) to have a higher density and the exterior doesn't really matter 'cause it's never baked). And create your baker mesh at the same time so that it's just a quad that covers the central tile.

Then you can bake in xnormal quite easily.

Yep, that's what the video suggests also. Maybe its time to poke around a little more in mudbox :x

Mudbox has a "Tiling Plane" mesh, but it's even slower than ZBrush's wrap brush. There's a lag after each brush stroke while it duplicates the results over to the other tiles.

Gannon

but mudbox can use alphas when you constrain brush strokes to a specific axis I don't necessarily need it to tile.

Farfarer

Yes, I believe so. Some of the brushes don't have an axis constraint, so you might want to avoid those, but most of them do.
