Just when I thought I was having an AHA! moment, .......
The wall pictured (subsurf, displaced plane, array, bezier curve and mapped texture applied) below could be straight. I was thinking I could apply a similar curve to it as done in previous images. Now I am reading, a plane that is displaceable in TG is one sided, okay.
Can you apply all of these warps and vector displacements to a cube, say that is thin and looks like a rotated plane? (perpendicular to terrain)?
I understand that the road is actually considered a terrain simple shape object, whereas a simple cube displaceable object is not terrain. I also read about rotating the object mask. Would you still have to use a warp input with that? Could redirect do anything?
OH NO! moment.
