I'm using one pfGeode to specify a terrain plane and another pfGeode to be a
set of lines representing roads. I'm using a pfLayer to (theoretically) lay
the roads down on top of the ground, but it doesn't seem to work. Instead of
solid lines on top of my terrain I'm seeing dotted lines because the roads
"submerge" in places.
Could this be a problem with the mode I'm using in the pfLayer? I've tried
PFDECAL_BASE_DISPLACE and (PFDECAL_BASE_DISPLACE|PFDECAL_LAYER_OFFSET) to no
avail.
I'm using Performer 2.1 on an Indigo2 running 6.2.
While I'm on the subject of terrain and Performer 2.1, is there a good way to
lay roads or other decal geometry on top of pfTerrain? We've been trying to
monkey with textures to do what we want, but it seems conceptually easier to
use a pfLayer node in the manner I'm describing above.
Thanks in advance,
Ed Peters
