Apply polar distortion to images in GIMP

[ModerndayLink]

Title speaks for itself, I have a texture for a planet I'm making and I cant seem to figure out how to apply polar distortion to the texture in GIMP,

so does anyone know how to do that?

Filter>Distorts>Polar Coordinates

edit the pole, then Filter>Distorts>Polar Coordinates and deselect the To Polar option. This will revert back to a rectangular map with a distorted polar area.

flip the image and repeat.

Is there a way to apply distortion without editing the pole (or basically just stretch the texture without editing anything by hand?) because I am still a Noob when it comes to drawing, and the planets texture was just generated using noise.

I'm assuming the process here blows Photoshop's polar filter out of the water? afaik Photoshop's one is a mule, not even a one-trick pony. There is so much I want to and/or must learn. And I'm kinda entrenched in Photoshop.

Nope it's the exact same in photoshop, nearly exact steps need to be taken in photoshop. I always go to photoshop first, Gimp is growing on me though for certain things.

No, that's the only way to achieve good results. The way you are asking about will result in awful looking textures.

I'm about to head home now. I must definitely try this.  Oh, does it work for skyboxes too?

You might wanna see a doctor for that.

No because skyboxes are applied differently in game they are in fact, a box that we fly around in. So, no poles.

For this particular situation, I recommend the clone tool then blending it in
