# Object being distorted when fixing lighting

So I have a problem with some unwanted wierd lighting on my model, which I would like to remove. But when i go to edit mode and use Ctrl+N to fix it. Then when i change mode to sculpt or object mode it comes out distorted like this. Any ideas how to fix this problem?

When dealing with sculpting it's very important to check whether your model doesn't have any flipped normals before adding Multires modifier (if you flip them after subdivided and sculpted, recalculating shouldn't make any problems. But making any changes in Edit mode on the sculpted model anyway will make you some distortions). You still can recalculate them at any time, but that will result in a mess you see in your case (or even worse).

There are several ways possible taking into account that sculpting must be saved:

### Smoothing faces with flipped normals

1. Enter Edit mode of the corrupted object, select faces with flipped normals and assign them to temporar Vertex Group.
2. Add Smooth modifier to this object, set created vertex group in the Vertex Group option of the modifier to make it influence only on it.
3. Set the Repeat value to something high, like 30 or 50, so to make messy vertices return to their place.
4. Recalculate flipped normals using Ctrl+N.

The Smooth modifier will let you make those faces / vertices stop being distorted and moved far away, at the same time the original sculpting in other areas will be preserved.

This way has disadvantages, of course:

• if there are a lot of faces with flipped normals it won't really help you - nearly all faces will be added to group smoothed by the Smooth modifier and that will be the same as just using Smooth brush in Sculpt mode or recreating from scratch all the sculpt.

### Leaving inverted normals

It's pretty straightforward - the inverted normals are left as they are, and you continue sculpting, including them if needed. You'll need to recalculate normals after applying Multires modifier (and probably make some adjustments even then).

The trick here will be that as the normals are flipped, the brushes will behave in the opposite way, so on these faces you'll need to use Subtract mode of any brush.
