Sculpt Subtract is painfully slow at small Brush Sizes

as title describes, the Terrain Editor’s Sculpt tool on Subtract is extremely slow when used at smaller brush sizes, even while at max strength. About half or a quarter of the speed of the Sculpt on Add.

Expected behavior

Subtract should at minimum operate at the exact same speed as Add. Ideally, please increase the max strength value across the board, as Sculpt is currently unusable at lower brush sizes.

Will look into this, thank you for the report.

Same issue here, its a real pain to do terrain now with the slow sculpt speed
Hope they fix it soon

Sculpting with brush size 1 (smallest size) has always been a pain, sometimes it works, sometimes it does nothing, I hope this behaviour is improved.

It’s also acting slow for me i don’t know why tho it wasn’t always like that

@VGVC2 @MTL2010 I’ve fixed this issue and am looking to get this through today, so that we can enable it next week. It also comes with some adjustments to flatten tool which currently runs wayyyy too fast on smaller brush sizes.

When we were improving brush performance, I changed the sculpt tool to make strength based on the brush size to some degree. Perceived strength for brush size 4 was definitely not equal to the perceived strength for brush size 64. We had the strength scale directly based on brush size, but after looking at this, I’ve realized that a logarithmic approach is better for scaling this properly.

Either way, the whole idea is that strength 1 always feels strong, while strength 0.01 always feels very weak, regardless of brush size.

Thank you for responding, but any update on when this fix will be enabled?

This should have been turned on today, please restart Studio with the latest update, and let me know if this is resolved for you. Also @bizbot19 @VGVC2 @MTL2010
