Pablo Dobarro (pablodp606) added a comment to D3594: New sculpting brush cursor.

@Pablo Vazquez (pablovazquez) The brush presets need to be updated to include the normal radius default value. Also, the grab brush preview on low poly meshes is a little bit weird, but it can not be done properly without an unnecessary hack.
Regarding optimizations, maybe adding Monte Carlo sampling only for the cursor is not worth it. If a computer can not run the cursor in real time it will not be able to sculpt. Furthermore, the cursor is disabled when a stroke is active, so sculpting performance should not be affected.
I think the rest of the functionality should be fine right now.

One more observation: Dyntopo being switched off occurs only when I smooth with individual strokes. So I hold down Shift, then I stroke, lift the pen, go back to the start position, stroke again, and so on, in a very fast pace, and holding Shift all the time.

Pablo Dobarro (pablodp606) added a comment to D3594: New sculpting brush cursor.

@Jun Mizutani (jmztn) If you set the normal radius to 0 the brush should not produce any deformation along the normal, that's expected (it is like setting the strength to 0). Currently, you need to change this value for every brush, and this needs to be fixed for the final version. I don't know why the default value is not taken into account, maybe we need to update the startup.blend file with new brushes that have this value set by default?

@Brecht Van Lommel (brecht) I starting to think that this is an issue with the normal calculation code itself, and now it becomes more evident because we are able to see it in real time as we move the cursor over the mesh.

Is the issue that some brushes like grab do not use the normal (unless you enable normal weight)? For such brushes we can show some other normal, but for brushes that do it use it why not show the actual normal?

Keep in mind that the vast majority of users will just use the default setting anyway, and while they are sculpting, you don’t want to have to care about setting this feature correctly.

Pablo Dobarro (pablodp606) added a comment to D3594: New sculpting brush cursor.

@Brecht Van Lommel (brecht) The problem might be that, in some task, you are only concerned about the cursor placement and not the sculpting normal. In fact, previewing the sampled normal could give you misleading information about the volume you are dealing with. For example, when you are using the grab brush to tweak the silhouette of the model you expect the brush preview to turn away from you as you approach the edge, and if we use the real sculpting normal that won't happen in some cases. I think we should give the option to the users to preview a "wrong" normal that follows the surface as long as they know what they are doing.

As I understand it that "normal radius" option is intended to make both the preview and the actual sculpting follow the surface more closely. I think that makes sense, it's the inconsistency that I find problematic. I suggest to use a weighted average with falloff. Simply blending the average and face normal will still be jittery, and a sharp normal radius cutoff will be less smooth.

Eoin O'Neill (eoinoneill.yokai) added a comment to D3594: New sculpting brush cursor.

Could it be possible to use the normal of a lower subdivision when using multires mesh modifier as a workaround for that zbrush-style behavior? Basically, when given the option, you use the resolution of the preview to guide a smoothing algorithm so that the brush preview is more performant on high res models? I don't know what could be done about using dynotopo, but for cases like the above, I would imagine the really high resolution details would be utilizing the multires modifier anyway.

Maybe the best option for now is to add the option to enable/disable sampled normal. After that, I could make a patch adding a normal radius option to sculpt mode. That will provide more advanced features in brushes (see D4235) and it will be possible to control how smooth the cursor is using the sampled normal method.

@ThinkingPolygons (ThinkingPolygons)

Actually this is nothing, really. Zbrush works pretty much like that, it never was an issue.

I just checked the difference. While the single face normal Blender cursor goes completely crazy on high frequency detail, Zbrush seems to have some sort of averaging on a small scale to prevent that. The cursor rotates only slightly there.

This sort of thing would be pretty distracting while sculpting:

Pablo Dobarro (pablodp606) added a comment to D3594: New sculpting brush cursor.

@Julien Kaspar (JulienKaspar) @ThinkingPolygons (ThinkingPolygons) I'm pretty sure ZBrush is using the drawing buffer information to sample the normal, so as long as the high frequency detail doesn't appear on screen it will not be taken into account. Also, that method has no performance penalty on high poly meshes and the cursor movement can be smooth even across edges in low poly meshes. I think this would be the ideal solution. I don't know if that is possible to do in Blender neither how hard could it be, but in any case, the whole cursor system would need to be rewritten from scratch to support that.

From my experience, I strongly prefer the face normal version. It is not that smooth, but it gives much more precise information about the placement of the cursor in the model, especially on the edges. When sculpting, that preview is much more useful than the real sculpting normal. Furthermore, I don't think the preview normal should change depending on the size of the brush when the placement in the model is the same.

I tried this feature in the build Pablo Dobarro shared on his twitter page, and I can say that this is already a hundred times better than the current brush cursor, even if it's not 100% accurate. The difference is like night and day. Every digital sculptor would love to have this feature.
Can't it be optional, so those seeking 100% accuracy could turn it off?

@Brecht Van Lommel (brecht) It could be even smarter, using some sort of clever averaging of the normal inside the brush area. That sounds like a good idea, as long as we don't cut off our nose to spite the face.

Just to be clear, I still think that this should preview something close to the actual normal. The fact that this displays a completely different normal in common cases is not good enough in my opinion.

This is great. We could even hide the normal mouse pointer cursor too and just show the center dot. The pointer cursor just gets in the way here.

I just tested it and I'm unable to reproduce the bug. I tried different brushes, settings etc., but nothing crashes blender in relation to this issue.

Can you confirm if this is still a bug? We had some commits related to autosmooth, and I can't seem to reproduce this bug on the latest master.
