Deformation in squish

When I use the Squish command on the slices of the ball there is a lateral displacement. Who will tell me what parameter is responsible for this?

Try first _ShrinkTrimmedSrf on that slice. Or use _smash command.

Not working. The task is to apply the texture of the earth to the ball, expand it with the texture and send it to print. After of patterns to make a model. Maybe there’s another way?

_UnrollSrf gives you a better result even if it theoretically doesn’t work with double curvature surfaces

Diego Krause, you’re right, it is. And the Smash command works much better. But what about when you need to expand the surface along with the texture?

I think that the only option for that is working with the uv mapping tools, unwrap the spere segment and make a pattern from the uv layout.

something like this

then you can print the unwraped mesh to apply a Hi res texture in photoshop or whatever, also you can overlap the smashed or unrolled surfaces to get the curves to cut it.

This is one way, but it does not give the desired result. The problem is this. How to force Squish to unfold a surface in the correct form as It does unroll or Smash commands with surfaces?

In other words, what parameter or way to affect the Mesh so that Squish correctly displays the lengths of the curves of the original plane.

I don’t understand if smash or unroll works well, why still trying to make it with squish? flattening a double curvature surface will always have a bit of deformation, so the precision will have a reasonable gap of tolerance.

It’s all about textures. Save the texture along the cut lines in another way does not get.

A reasonable expectation of Squish would be that a symmetric surface would remain symmetric when flattened. Attached is an example of a very simple singly curved (id developable) symmetric surface which bends 180 degrees. Flattening this surface with Squish using both the Rigid and Floppy options results in asymmetric results. .Interestingly a second surface which is one half of the first surface when flattened with Squish produces results as expected.

I had to spend the night squishing, but I never found a way to preserve the original geometry without breaking it into additional parts. And the cause of the distortion is not clear. So, if you are using squish you don’t know in what cases receive a good result, and what is not.
