I wish there was some polygon ones but the remapping in the tce is where I have my #1 problem.

I use the sculpty models that were packaged in a zip for everything I make.

I think the two hardest things are the tce and figuring out how to divide things up more to get some precise details to stick. This is great but IвЂ™m lost on this part вЂ“ Create your two shapes in AC3D, but make sure they are joined together when you build themДo you weld them together? IвЂ™m still wanting to use polygon models but the maps are never working out even though they look to be in the tce.

Tags: 3d graphics, 3d modeling, ac3d, sculpted prims, sculpties, second life, SL, tutorial For advanced users, if you have very complex shapes you might want to use an LSL script to change the mapping mode cylindrical and torus can be very helpful here, especially if you need a hole in your shape. If you are a novice at texturing, IвЂ™d recommend starting with one of the base shapes and modifying it to make your double-shape sculpty rather than mapping one from scratch until you get a better sense of how it works. Complex shapes will take some practice to learn how to map this way. Notably, this will be much easier to do with some shapes than others, especially if you are new to uv mapping. Note again that both cylinders share one uv map that is completely seamless: Note the ring of degenerate triangles connecting the two cylinders:

HereвЂ™s what my double-cylinder looks like in AC3D. In this unusual case, we want the degenerate surfaces, so donвЂ™t optimize!

Side note: donвЂ™t optimize the shape when you are finished! AC3DвЂ™s vertex optimization will weld the vertices and more importantly AC3DвЂ™s surface optimization is specifically designed to remove degenerate faces. When youвЂ™re finished, export the sculpt map as normal. You can use Vertex > Snap Together to move the vertices if need be and make sure they are completely aligned. You want to make the triangles connecting the two shapes completely degenerate. Once you have the shape mapped correctly, grab the triangles connecting them and scale them until they are completely flat. Like all other sculpted prims, the usual rules apply: No holes or gaps in the texture coordinates, and the texture coordinates must fill the entire uv map. A smooth, continuous uv map should completely wrap both shapes. Texture the shapes as if they were all one object. So how do you do it? Create your two shapes in AC3D, but make sure they are joined together when you build them. The degenerate triangles will be dropped by the video card and you will end up with what looks like two perfectly separate shapes on the screen. With degenerate triangles, itвЂ™s like the geometry didnвЂ™t even exist in the first place. Alpha mapping just hides the geometry with a texture. By connecting the two shapes you want visible with degenerate triangles, the geometry connecting the shapes wonвЂ™t be rendered by the graphics card at all. We can exploit this functionality to make one prim into two. Video cards can render faster if all the triangles are sent in one long strip by discarding degenerate triangles, video card designers allow game developers to concatenate long strips of triangles that might otherwise be impossible to join together. Many games use this feature to connect triangle strips. Most video cards are designed to silently discard degenerate triangles automatically. This means that the triangle has zero thickness itвЂ™s just a line. A degenerate triangle is a triangle where two of the three points lie in the exact same location. The secret is to use degenerate triangles. This creates a problem, because if sculpted prims are really just spheres, how can you make one sphere into two shapes? Technically, you canвЂ™tвЂ¦ but with a little knowledge of how 3D graphics cards work, we can set up our geometry in such a way that the graphics card will render one piece of geometry to look like two. This means that all sculpted prims are in fact deformed spheres. Each pixel in the sculpt map is a 3D displacement of a vertex on this sphere. Two disconnected shapes made with one sculpted prim.Д«y default, Second Life generates the geometry for sculpted prims as a sphere. Today IвЂ™ll show you how using the AC3D exporter. The answer is yes, you can! It can be a little tricky depending on the shape, but it absolutely can be done.

Many times people ask me if itвЂ™s possible to create two disconnected shapes from one sculpted primвЂ“without resorting to alpha maps.
