Terrain Sculptor Version 1.1.1 - Addresses Login Error

Some users with some accounts get this error message when logging in through Terrain Sculptor 1.1: "Error retrieving the login response from the server". This is caused by an issue in libsl. It doesn't effect every account; it seems to effect avatars with substantial inventories. If you are getting this error using Terrain Sculptor 1.1, one option is simply to try logging in with an alt with a small inventory. I've been using the tool with an alt without any problems, even though my main account gets the login error.

Another option is version 1.1.1 of Terrain Sculptor. The login issue has been fixed in libsl by a new login system, but the new system is not part of an official release yet. Version 1.1.1 of Terrain Sculptor uses the development version of libsl to avoid the issue. In theory the development version is not reliable, but I haven't run into any problems effecting Terrain Sculptor yet. One difference with the new version is that logins and teleports often seem slower.

As soon as an official release of libsl with the login fix exists, I'll be updating Sculptor to use it.

Terrain Sculptor Version 1.1

Terrain Sculptor version 1.1 is now available. Terrain Sculptor is an open source program I've written which uses a libsl bot to automatically map sims and generates sculpty textures of their terrain. The key updates in this version are planar sculpties and avatar movement. (v1.0 Blog Entry)

1.0 used the default spherical projection for sculpties, which meant the sides wrapped under and joined. 1.1 uses the planar type, which produces a sculpty much like an actual sim in SL. Unfortunately a script is necessary to change the sculpty type to planar, but one is included in the README (and see below). The "decal" versions of the web map image are no longer generated because they are not neeeded with a planar sculpty.

Second Life has gotten more clever about recognizing when terrain is visible to an avatar, and it doesn't send terrain data that the client doesn't need to render. So I've added the ability to move the avatar around to force all the terrain into view. The avatar's position is updated automatically on the web map image of the sim.

Download the application.

Download the source code and Visual Studio project files.

Here is the script to change the sculpty type to planar. I thought I'd post it here because people might find it convenient for setting planar sculpties in general. First drag the sculpty texture into the prim's inventory (it should be the only texture there). Then place this script into the prim's inventory. It will automatically set the sculpty texture to the texture in the inventory, set the sculpty type to planar, and then delete itself.

string theKey = "";
string theName = llGetInventoryName(INVENTORY_TEXTURE, 0);
if (theName != "")
theKey = llGetInventoryKey(theName);
if (theKey == "")
llOwnerSay("No sculpty texture found");
llSetPrimitiveParams([PRIM_TYPE, PRIM_TYPE_SCULPT,
llOwnerSay("Sculpty texture set to: " + theName);
