vertex painting is one option but I am looking into the vector displacement sculpting option purely for speed and or laziness depending on how you look at it. Some surprising results from mudbox at the moment just using the imprint sculpt tool a bit hit and miss because of the photos I am using, stalactites are roughly the same as ice stalactites only mineral based and the photos have darker backgrounds. Have to isolate them in ps which is proving to be a major pain
This was done using the "sculpt using map" function in mudbox. Next stage is to get the icicles into modo cut them out individually and mirror (will probably be an ass to do) for a full model of an icicel.
I will doing more tightly clustered icicles but it requires a lot of PS work.
Would the equivalent of "sculpting using map" in ZBrush just be importing a height map as an alpha and messing with the deformations and sculpting?
Yes but in mudbox you can simply add any photo and use it as a stamp or displacement map that covers the mesh (depends a lot on the source quality/res).
One of mudbox's strong points imo.
Doing it the lazy way for now (as you can see by the image noise) to see what I can come up with :poly136:
haha yeah it's a tad bit on the noisy side, but why try to perfect on something you're just trying out. Keep up with the mini tutorials! Looks like it's turning out nicely
One other thing you could do, which might be cheaper, is this:
a single channel gradient map, which is used as an alpha test (you could multiply & clamp to make the icicles grow or shrink) and as a steep parallax map. Aught to work decently enough for 'skirts' of icicles around objects.
You could use the other channels for translucency or specularity or distortion or whatever.

Will post some pics when I get there !!!
Thanks for the info.

Nevermind, totally realized that was already posted. Sorry.:p
