Sculpting bug involving Grab dynamic radius, smoothing, and layers... (destroys undos)

Bug reports

I’ve been running into a bug that seems to occur when either smoothing on a layer with a grab dynamic radius or doing other operations like that, which then causes that layer to instead corrupt the BASE model, as well as all previous undos.

it’s a difficult to tell when this is happening as things seem normal as I’m working, until I hide the layer at which point the base model becomes corrupted and “spikey” and this seems to be not undoable.

You are on Nomad 1.71?
DynTopo? Non uniform scale in the matrix or not?

in this latest case none of those, let me see if I can replicate this behavior,

it does seem to occur more often when some layers on the object arent set to 1, but it almost ALWAYS occurs when I use a brush via grab radius (usually for stamping alphas)

Ive figured out how to reproduce the bug that destroys undos, I simply start using stamps on a layer that is set to more than 1 strength and then smooth it via another layer corrupting the base object

The bug is caused by the offset being > 1.0 (should work fine if < 1.0 or even negative).

yeah I figured the layer multiplier had something to do with it, I will say I am using layers going >1 quite a lot so I hope that stays in :slight_smile: I am really loving nomad so far even used it working on a few shows I worked on for a quick starting texture work!
