Hello Martin,
First of all thank you for taking time to put together your tutorial.
I am trying to walk my self through your tutorial and emulate a scene similar to what you have done. I have an issue and a few questions. The procedural canyon generation seems to be causing me issues.
I have a series of white lines that run outward from the surface of my planet to what appears to be infinity. I have attached my nodes and an image showing one of the lines.
Any ideas what could be the cause of these?
Also I was wondering if it would be possible for you to post a clip file of your procedural canyon.
This would assist me greatly. Thank you!!!
