This picture had 8 backups, and at the end was doing the 'bryce will close now errors'. Ok, so i gave up and back furthur back to before any models were imported in the end (As i liked the overall feel of the terrain and colours.) Every thing appeared to work fine at the basic level. Then after 2 more saves starting way back noted weird lines in the picture. Note the vertical stripes sticking out of the ground on the planet to the left. These had a appeared 3 saves later but i backed back to the basic pic even furthur only to have them appear in a another totally different spot. Once again they have appeared for no reason, there are no abnormal issues in the terrains, no areas of strange spikes. Therefore dont know why they would suddenly appear. Ill go back one more time and try and last thing or 2 but after this much work and restarted over and over, likely ill abandon it if the next try dont work.
