I want to retopology the thorns.

taki39

I made thorns with zbrush.

There are a lot of thorns.

I want to re-topology to develop UV.

I used zremesher.

However

The thorns will collapse.

Available software

MAYA,blender,zbrush

How can I succeed in retopology?

Zbrush decimation is the most likely to work . You will probably have to mask it though

Thank you for your reply.
 I will try Decimation Master.

 [You will probably have to mask it though]
Does it mean to mask only the tips of the spines?

poopipe

 I imagine if you mask by curvature you'll be able to maintain the points and bases of the thorns

is curve this mask?

taki39

I used a mask curve.
 I am currently using a mask.
 Should I use Decimation Master in this state?

poopipe

Not that.

I'm not that familiar with zbrush anymore but I believe you can mask by mesh curvature or tension.
What you're looking for is to have the point and the base of the thorns masked so that the decimation leaves them as they sre

under tools > masking

lots of buttons there you can just push and see immediate feedback

also handy thing in zbrush is hold CTRL while hover over the button and it gives info

Decimation in zB calculates surfaces with more detail and tries to keep that detail by only (or more heavily) decimating parts where it can reduce resolution easily like flatter surfaces. Getting the most out of that feature you have to decimate in stages. first 20%, then 10%, 5%, 2%, 1% . You just decimate as far as you can using the undo slider to step back when your mesh goes boing.

Thank you for your advice!

 I made a thorn with Sculptris Pro and Snake Hook.

I challenged the masking you taught me.

I couldn't make an accurate mask...

I was able to reduce polygons with Decimation Master.

Do you have any problems with triangular polygons?

Is it not necessary to make it a square polygon?

The purpose is a creature used for concept art.

There are no plans to move it in the game.

I have MAYA and Blender.

Is it the easiest retopology Decimation Master?
