Can't get adaptive subdivision to work #2

Closed MoritzStefaner closed 2 years ago

MoritzStefaner commented 2 years ago

Hi,

thanks for the great tutorial! I got everything to work, but my renders still look pretty "flat" — see attached sample render:

I think the adaptive subdivision has no effect. Any ideas?

Hmm..

Does increasing the scale value in the displacement node have any effect?

If not, you could share the .blend file and I could take a look

MoritzStefaner commented 2 years ago

Nope, no change as far as I can tell… The main difference to your setup is that my elevation file was 12000px x 12000px, so maybe that causes some scaling issues.

Attaching the blender file — thanks for your help!

I think I found the issue!

With the plane selected, go into material properties > settings > surface and under displacement select 'displacement and bump'

I must have missed this step in my tutorial!

Let me know if that does the trick,

thanks for helping me improve it :)

Yes, that's it! 😍

Noice!

P.S. If you want to prevent coastal areas from looking 'flooded' you can follow the extra step in the tutorial by creating a mask using polygons for France and Italy (if you don't have them you can use natural earth data - in QGIS select France and Italy then export > save selected features)

All the best, Joe

Wonderful, thanks! This is a lot of fun :)
