I am using an RTX 2080 laptop. Thanks for testing. Will do some troubleshooting to see what might be causing the lagging.

We got a few changes in the latest patch notes for Sculpt Mode. Now more operators are disabled based on objects being invisible or not.

Does anyone know why this is happening?
Iā€™m using multires
Blender 4.0.2

2871

Maybe thereā€™s automasking activeā€¦?

2872

There is no automask, start a new file for testing, unfortunately this anomaly continues!

2873

jpg in the brush alpha is scary. does it happen if you try a different image tiff psd pngā€¦ ?

2874

The best format for large displacements in Blender is .exr actually (as the GPL does not allow Blender to have proper support for the proprietary .psd format). EXR is an open format.

Why it works is because their format supports what is known as deep color (a standard 32-bit color depth is insufficient if you are using a very high mesh resolution).

2875

Yes, I used TIF and the error continues

2876

I will write this text
Itā€™s discouraging to think about converting so much alpha, but if itā€™s the solution, so be it!

2877

canā€™t reproduce your issue!!!
i assume youā€™re using Anchored try to take of the alpha and just do it with the circle (standard brush falloff)
i just think itā€™s a combination of low res in alpha + low res in mesh
subdivide more and see if the effect change

2878

something else i noticed if youā€™re using a tablet in the test, try to disable the pressure for the strength and see if itā€™s the same behavior. or test with a mouse

Post the blend, people will be able to help you a lot better than just speculating.

test .blend (476.4 KB)
The file

2881

I have no issue with you blend file.
The brush does not seem to have a weird set-up.
So, I suppose problem is relative to image, you forgot to pack.

2882

edit:
was curious and opended it in 3.6 and there is a big difference!!! so there is an issue i think :thinking:
big difference between 3.6 and 4.0.2 with the same alpha . he is right

2883

test .blend (2.2 MB)
Pack

2884

I edited my post above: no need for the texture it is an issue in this version

2885

I used 3.6 and the difference is dramatic

2886

That is relative to Front Faces Only option.

2887

Yes, it is because Front Faces Only is checked. But it must be a bug in 4, because it works fine in 3.6 with that option activeā€¦ :man_shrugging:

I think itā€™s worth a bug report
