To repro: Set the parcel url to a previously updated image file (we used the standard banana sculpty), then set a script to llSetPrimitiveParams the prim from a non sculpty type to sculpty type, using the texture that will be replaced by the url. First bug, if the image file is very small (128x128) then the 'webpage' you get is mostly random bit junk (this is viewing the url as usual, not as a sculpty). So we resized the banana sculpty to 1024x1024. Now the image loads fine viewing it as html onna prim. However, changing prim type to sculpty type from an already sculpty type appeared to do nothing. Changing the prim type to sculpty type from box type did change it to a sculpty, however, the resulting sculpty is 2 dimensional! The z-data seems to be lost (and the rotation of the sculpty prim is unexpected. My banana is now flat.
