Thanks Jim for updating the plugin !!

Here's something I'm playing with: Drop TIN.

interesting, looks kinda like a mixture of DRAPE + STAMP... or a STAMP with variable height?

Could this plugin be updated, (or in the case another plugin exists, please point me out)in order for a more smooth randomization to be possible? Right now, the plugin simply changes the vertical distance of every vertex in the TIN by the amount set by the user.
However, it creates some artifacts often due to the normals, and even not counting the artifacts, you just can´t get a smooth random terrain, specially if you want bigger random elevation...
Only way I found to achieve that was repeat the process inumerous times...
Create a TIN with Soap Box and Bubble in a way the squares will be like let's say 2x2 meters. Apply randomize TIN with 0,7 meters of vertical displacement.
Notice this is a low resolution terrain... but if you want high displacement with Random TIN, you need a low res terrain, otherwise you might have two points 20cm apart, one of them 1 meter high, and the other -1m!!
After randomizing with high displacement a low-res terrain, then you ADD DETAIL... run Randomize TIN again, this time with smaller vertical displacement (say, 0,3 meters), add detail again, run Randomize TIN again this time with 5cm only.

worth mentioning however that if you create a low resolution TIN and it has a complex shape (like you made it with Soap Skin Bubble, or you have cut it after stamping) you might get some problems. Therefore if the plugin had automatic smoothing either after or before creating it, it would be very good.
Example... only move in the vertical vertexes that are at least 5 vertex from each other (or set a distance in meters instead of number of vertexes) and then the ones in the middle have their height calculate based on average/medians?
