(solved) Smooth shade an extruded plane gives me a mesh distortion

[sudden wraith]

I have created a plane with a custom shape and then applied a solidify modifier to extrude it. If I then apply smooth shade then the mesh gets distorted, I don't understand why.

[pine echo]

whats the mesh like?

[sudden wraith]

it's this one

[pine echo]

no like

in wireframe

[pine echo]

hmmmm

[sudden wraith]

the small squares are other objects

you can ignore them

[pine echo]

idk what’s causing it then

it could be because it’s a purely flat objects

[sudden wraith]

weird isn't it

[pine echo]

it’s trying to smooth something sharp

make ad like

a slight bevel modifier

[sudden wraith]

if I apply a bevel mod then nothing happens, I mean I can't see any bevel

[pine echo]

wow

[sudden wraith]

oh hold on

[pine echo]

uh

idk then

[sudden wraith]

now it's applying the bevel

let me try to smooth

[pine echo]

ah mk

[sudden wraith]

it worked 🙂

[pine echo]

yay!

[sudden wraith]

I didn't think about the sharp edge

it was a recurrent problem

thank you for the help!

[pine echo]

right!

The reasons I think your mesh got distorted are:

1. The top face is a multi-sided polygon. Generally try to make it all quads. For this mesh ig you could try deleting the top face and using Gridfill to get Quad faces.
2. You haven't checked Auto-Smooth. It is under object data properties > normals > Auto-smooth.

Good suggestions I never used gridfill is it an add on?
