Well I am on Firestorm 4.4.2 and it's still an issue. Even more so, if I have a megaprim sculpted as sim surround scenery it often won't rez, so I attach it to an on-sim object to give me something to click on. Boring.

Edit the object, select the Features tab, and change the Physics Shape Type from "Convex hull" to "Prim"

I have tried using script to terraform land, starting from 0 height everywhere. The results are rubbish. It's ok if you want to raise one hill, but to raise a sim landscape from, say, notecard information, the terraforming is simply too slow to keep up with the script, which misreads the height as it is being modified. However I have deduced some information about brush size, if it's useful to anyone. BRUSHSIZE 0 area affected is 2m x 2m BRUSHSIZE 1 area affected is 6m x 6m BRUSHSIZE 2 area affected is 10m x 10m Repeated use of the smallest brush results in an area with very steep sides, but results vary with exactly where the terraformer is located. For example using brushsize 1 and varying the x-position slightly x.00 metre location, east slope was steeper than west slope x.25 metre location, east slope was steeper than west slope x.50 metre location, hill raised was slighty to west with even slopes x.75 metre location, hill raised was slighty to west with even slopes

Maybe it should not be in scripting but here is some kind of answer. The terrain file is 256 x 256 which maps to the sim coordinates at 1 m intervals starting from (0,0) in the south west. If the sim is unconnected to others, the 256th element is copied from the 255th so the north and east edges are flat in one direction. But if the sim adjoins another, the 256th row is obviously the 0th row of the next sim. If you want to make a sculpty that matches terrain, its X and Y size must be such that 1/255 (the sculpty measurement unit) is an exact fraction of 1 m. For example, if you use a 255 x 255 m megaprim, the sculpty units are 1 m. Another example, if you use a 63.75 x 63.75 m prim, then 4 units will equal 1 m. As for the height, you will have to experiment because the terrain heights might be scaled to 1/8 m or 1/4 m steps, etc. The easiest way is perhaps to scale the terrain height range from 0 to 255 and then play with the sculpty height until it fits the terrain.
