When I visualize Distance Field Ambient Occlusion in the editor, I can see the correct shape of objects.
However, when I try to do something similar with a material using DistanceToNearestSurface, the shapes look strange. Also I would expect to see a gradient and not only black and white.
It feels like I’m not understanding distance fields correctly. Can anyone point me into the right direction?
Thanks. I see the transition now.
In the pictures above, a static mesh plane is intersected by a sphere, cube and cone (all with a transparent material). The DistanceToNearestSurface-Material covers the static mesh plane. So, for the lerp alpha should be ~0 at the intersection areas such that they are painted white. But it’s just the other way around. Why is that? How can I modify my material, such that the intersection areas are precisely colored?
The initial problem I had is described here: https://answers.unrealengine.com/questions/350101/is-it-possible-to-draw-objects-which-are-sliced-by.html
With “regular” materials, you can see how the static mesh plane intersects the sphere, cube and cone:
In my case, the sphere, cube and cone are transparent/invisible. I depict this with a grid:
I would like to paint the area where the static mesh plane intersects the sphere, cube and cone, like this:
I believe that this can be achieved by covering the static mesh plane with my DistanceToNearestSurface-material if I configure it in the correct way.
I.e. following the logic:
IF inside sphere/cube/cone
THEN color = red
ELSE color = white
It should be possible to determine “inside” using DistanceToNearestSurface, right?
I hope this is clearer now. Otherwise please tell me and I will try to clarify more.
The visualization of the DFAO seems reasonbly accurate to me. Or do you have any idea how I could solve my problem otherwise?
Have you figured this out?
Unfortunately no.
Try upping the distance field resolution by a HUGE amount on the meshes?
