unwanted geometry changes on changing shape keys

[Arshdeep Singh]

Hello! I am getting an error at corner of eye, when I am trying to change the shape key I get unwanted geometry changes mainly where the geometry overlaps like the corner of eye, corner of lips and at tight creases. (silly bug fix does not work)

Can you post screenshots or a screengrab video? Just to get a better idea of what’s going on.

I INCLUDED MY FILE ALSO.

Hi Arshdeep @Arsh ,

The corner of the eye is a bit funky as is with overlapping Geometry,, (even without the Shapekey):

Maybe you can Smooth that area and redo the details?

The mouth corner only has two spikes, I think; you should try to carefully remove them by clicking on the points a few times with the Smooth Brush (full Strength) (you need to get inside the model at some point):

Furthermore: try to avoid switching between Multires Levels. Also (I am not sure about this one) I would try not to (simple) Save your File anymore: only Save iIncrementally.

I already fixed the mouth but the problem is with the eye, When I try to fix it with smooth brush it works but when we switch between shape keys it automatically generates spikes again every time (this is not the issue with mouth).

And Thankyou Martin Bergwerf for helping me every time.

Hm,

I tried smoothing the eye corner and with me it doesn’t create spikes, when then switching between the Shapekeys…

I don’t know, maybe you didn’t smooth enough?…try smoothing, with Face Orientation Overlay on…

[Arshdeep Singh]

can you tell what blender version you are using

[Martin Bergwerf]

I tried that on an ‘old’ one: 3.6.1, but there shouldn’t be any difference with 3.6.5

But this sort of thing can be really tricky to solve. I had about 30 spikes on both the mouth and the eyes (on my own model)….I managed to fix them eventually, but it was a lot of going back and forth between smoothing, switching Shapekey and smoothing again…In my experience, smoothing, then Saving and then switching seemed to make it worse.

[Arshdeep Singh]

man, sorry for disturbing you but can you send me a video of you solving it. Because I can’t figure it out.

[Arshdeep Singh]

please use my .blend file for this

[Martin Bergwerf]

@Arsh,

Sure, I can do that, but it’ll have to wait until tomorrow.

[Arshdeep Singh]

Martin Bergwerf ,

Thanks

[Martin Bergwerf]

Sorry arshdeep @Arsh

I hadn’t paid attention yesterday and was looking for huge spikes. The eyes closed doesn’t get completely clean, but, as long as you are not going to pose the portret with closed eyes, the result should be fine; the main part of the eyelid is already detailed and the edge can be done with open eyes, I think.

This is what I got after Smoothing (full Strength of the Brush):

And this is what that looks like with the Shape Key enabled:

I didn’t think it was worth making a video, it’s really only a few strokes with the Smooth Brush (done with the Mouse even).

[Arshdeep Singh]

Yes, but the real problem was when you try to change shape keys it creates errors automatically. (It would be really helpful if can the solution to make it ok) (It is still ok if not)
