I do see the "bumpiness" or noise I am expecting to see, although in the foreground it is admittedly less noticeable. Do you have Fractal Detail enabled in your height data loader? If so, try turning it off and let's see what that looks like in the foreground. For the bumps I mean, look in the background, either at that lower line of small hills to the left of the 100m sphere, or the ridge/cliff line above, more visible on the left side. The regularity of those bumps looks to me more like data noise than actual detail, but I could be wrong.

I've always found applying clips onto real world data to be very challenging. As Oshyan suggested it might be easier starting with no fractal detail, although figuring out the PFs to substitute in for the basic fractal detail is also quite challenging (for me anyway  ;)).

Are you using "Smooth surface" in the compute terrain node?

Oshyan

I believe Fractal Detail does some unique things that are supposed to key off the base terrain shape a bit, so it may be difficult or impossible to really duplicate it with other nodes. That being said I've found its effects to be problematic when working with certain data sets, particularly noisy ones, or ones with other errors/issues; it essentially can magnify existing issues since it is trying to create "complementary" data. So in some cases it may be better to aim more for using the base data as your underlying structure, and try to replace the fine detail as much as possible with your own surfacing work.

Hi,

Can any of you guys help me with importing and correctly aligning MOLA & HiRISE data into TG3?

Thanks!

If we do manage to get to mars, they had better train one of the astronauts in landscape photography. You would think they can make room in the budget for a few lessons.  ;D then perhaps, we don't have to have any more questions about that bit.
