Normal Displacement (v. 1.2)
(Layout displacement plugin, LW7.5 and later, not tested
with prev. versions)
Q: Uh? Doesn't Lightwave have a Normal Displacement? Why would
i want this?
A: Right, it does. And this plugin initially didn't really do anything
new. But i found LWs NormalDisplacement awfully slow and it produced
artifacts wherever possible... :-/
The Bump Displacement added to LW7 (right between Displacement Map
and the Add Displacement button) didn't really give me the desired
results either.
So i just started out clonig the Normal Displacement and added some
little features:
Luminace Center, i.e. which color is interpreted as zero displacement,
so you can have positive and negative displacement with one map.
Evaluate Before Bones or World Coordinates. However, it didn't work
out as expectes as Before Bones actually doesn't give me the SubPatch
cage when having SubD order set to "After Bones" so it
does nothing then *hmpf*. Have to ask Newtek what's up with that
weirdness...so displacing a SubPatch cage is simply impossible.
Vertex Size enables you to influence texture antialiasing.
Version 1.1 added some envelopes, by multiple requests :)
btw, you might also want to check out the 16bps
TIFF-loader.

Brak!
Attention: When version 1.1 or newer is installed,
scenes saved with version 1.0 will not load correctly anymore! This
means the whole scene, not just the displaced object! Unfortunately
there is no easy fix for that, as i should've written v.1.0 differently
to prevent this, but i didn't know at that point :(
Sorry for that. All newer versions should be compatible to each
other...
It is however possible to edit the scene file (with any text editor)
to make LW load the scene correctly except the enveloped values.
Oh and one more thing: The maximum number of ND instances per object
is 10 now, however i never tested if with the old version more then
one worked properly at all...
