Sculpt tool going crazy?

#1

Is there anyway to reset the falloff or whatever maybe causing it? It seems to go really crazy even with a low strength setting?

Thanks

If you get this behaviour in Mud it’s usually a scale issue. It’s a good idea to match your object’s scale4 to that of the mudbasehuman/head in your 3D app.

I loaded the head mesh and give or take, its on the same sort of scale.

I made 2 circles on my object. The one of the left is a circle motion which I have drawn twice - one after another with the sculpt tool. The one on the right is a circle drawn once. Same tool.

When I keep moving over the part of the mesh with the sculpt tool it just goes nasty like in the picture. Is that how mudbox operates?

Are you using a mouse or tablet? have you tried lowering the brush strength way down?

#5

Hi I am using a mouse…and at 0.8 strength, as you suggested, works just were it feels comfortable!

But the difference in strengths are huge! 0.8 seems like an odd miniscule amount to dial in, but hey it feels better there…
Does it feel good with a tablet?

EDIT: maybe its going to take me a day or 2 to get the swing of things. I have been only playing around with it since this afternoon

Yes it does indeed feel ALOT different with a tablet :smiley: If you really want to reap the joy of sculpting then a tablet is a must.

Did you scale your model in Mudbox? Or was it already a similar scale to the Mudbox base models? If it was the former then either scale and reset transforms in whatever package you made the model in, or export and reimport the model to OBJ format from Mud.

If that’s not it, then maybe your BuildUp rate is too high on the sculpt brush. Look in the brush options side panel and try turning it down.

Even if you are using a mouse, it shouldn’t be building up that quickly with that low a strength.

maybe something is screwed up…
try to delete the settings folder in myDocuments\mudbox…

Will try your suggestions and report back, thanks!

Worth checking your workflow for this (just in case)

1 - rescale model
2 - re-import to scene (if you do not it will not bake this new scale to the mesh and still treat it as a small mesh).Use OBJ and NOT fbx as fbx will not curently bake out the scale changes when re-imported a lot of times.
3 - watch out for very large polygons next to very very tiny ones… “a road to badnesss they are” as yoda might have said.

Just as a sidenote…what tablet do you use? Would a Bamboo tablet be a good buy? Looking at the prices of those intuos ones. Wow. £600? -

That one costs more than my pc!

I have an old Intuos 2 I inherited from my old job and an even older Graphire that I use with the laptop to save having to move the one around. Both of those are fine. The Intuos has greater sensitivity and a better stylus but they both work OK.

I haven’t used one, but I understand the Bamboo is better than the Graphire used to be, so should be fine. Which ever you go for, try to get an A5 or 6x8 size one. The smaller ones are too tiny to get much accuracy from. Some swear by the A4 ones, but I think I’d find them too big to put anywhere. And they are very expensive.
