The herring is a good choice because it is a smooth, organic shape. This model was not built specifically for Second Life but it does have all of the features that make a good sculpty. Organic models, on the other hand, will usually export with much more pleasing results.įor this tutorial, I’ve selected an old model of a herring that I had sitting on my hard drive. While it is still possible to export these models as a sculpty, they generally require much more tweaking of the UV map and may still suffer from visible artifacts. Models with sharp corners or flat surfaces are best made out of the other conic primitives that Second Life provides. – Rigid man-made shapes such as a square table or desk, or anything with 90 degree angles – Hard points or large numbers of small protrusions – Models with sharp corners and very flat surfaces On the other hand, you’ll want to avoid these kinds of objects: – Organic shapes such people, fruit, animals, plants, landforms and soft clothing – Heavily subdivided shapes that are very smooth
– Models with smooth flowing curves combined with natural lumps This means that some kinds of models are better suited to make into sculpties than others.Specifically, the following types of models will normally convert easily and make very good sculpted prims: Remember, according to Linden Labs, sculpted prims were designed specifically as an approximate representation of organic shapes. Start by selecting a model you wish to convert to a sculpted prim.

If you don’t have the AC3D export plug-in for SL yet, you can read about it and download it here. U and V refer to the 2D coordinates in texture space of a vertex, in the same way that X, Y and Z refer to the 3D coordinates of the vertex’ position. Basically, a UV map says “stick this piece of bitmap to that part of the model”. UV Map – The layout of the texture coordinates of the model. Sort of like a topographical elevation map you might have seen in geography class, but it contains 3D data instead. Sculpt Map – A 3D displacement map used by Second Life to make a sculpted prim. Sculpted Prim or “Sculpty” – A Second Life 3D primitive whose shape is determined by a bitmap.

This tutorial provides a quick walk-through on how to setup a pre-existing model for import into Second Life using AC3D. While not all models are good candidates to become sculpties due to limitations of the sculpted prim format, a surprising number of models can be converted quite well–including many pre-existing models that were never designed for Second Life. The AC3D “sculpted prim” exporter for Second Life has some unique capabilities versus other sculpt map exporters it is one of the very few that is capable of exporting an arbitrary polygonal model.
