Rubidia

[TheBlackHole]

Rubidia is a terran planet orbiting the K-class star 13933565-134443923.13QEW. Its plants are red, due to the pigments used for photosynthesis not being chlorophyll. This results in the planet's land appearing to be red, hence the name Rubidia.
I had a few problems making this. I noticed strange parallel lines in the terrain, so I moved the camera away from them. Then I noticed similar lines in the clouds. Changing render settings and removing a surface layer I'd been using to fade out the clouds at higher altitudes removed the cloud lines, and removing another surface layer I'd used to try to get beaches may have removed the lines on the surface. I have no idea why surface layers would contribute to lines in both the power fractal and the cloud fractal.

The removal of the surface layer was one of the things which solved your problems.
Still, at higher resolution and higher settings the problems are way less.
Besides that, at higher resolution the image looked a lot more realistic, so I encourage you to render it at 1600x900 or 1280x720.
I added some extra info in your other topic.

Good looking planet render. I like it! I am a fan of all Sci-fi planetary art. This one looks very realistic.
Excellent job!
I also like your way of thinking about the planet´s name and the reasons why its like that. Makes much sence.
I would want to visit that world one day.
