You only must ensure that the objects conform to the mesh topology of sculpted prims: - They MUST be unwrappable to either: - a simple rectangular plane - a simple cylinder with one seam - a simple sphere with one seam and one pole at the top and/or one pole at the bottom - a simple torus with 2 seams. - They must only use Quads If the objects topology derives just a tiny bit from these constraints, the UV-map resulting from sculptify Objects gets borked. Sometimes it helps to predefine the seams before you do the sculptify objects. But honestly this is not a simple task. Often the deviations from the constraints can only be seen by close and intense insepction. you can use all techniques provided by blender to create your objects.

Sorry for the late response. Sculpting is not an easy task. And sculpting with blender is combined with understanding the tool first. And blender 2.4 is known to be a challenge for many people. We have tried to lower the entrance barrier with this blog. But if you just started, then you might want to first go over the "beginners" tutorials. You will see then that the technique shown in this tutorial here is not soo complicated. But it is addressed to more advanced users. 1. How could I get the glass transparent? You make the glas transparent by either applying a transparent texture or set transparency in Second life. You can create transparent textures with blender or Photoshop or any other 2D tool. 2. Why should I do anything with texture map in UV window only to correct shape in 3D window? You actually do not modify the UV map here. You just use one very neat feature of the UV-map editor which allows you to find the seam in the object easily. Of course you could also try to find the vertices before you actually sculptify. But using the UV map is just easier. 3. Is there any difference between “import as sculptie” and “classical” way “bake – save image – SL upload”? - "Import as sculptie" takes the current sculptie-map in the UV image editor and creates a 3D- model from it. - "Bake" takes the current model in the 3D viewer and creates a sculptie-map from it.

– “Import as sculptie” takes the current sculptie-map in the UV image editor and creates a 3D- model from it.

SL can not import small sculptmaps with viewer-1. With viewer-2 there are less problems. In order to workaround this limitation of Second LIfe, you can do this: - go to edit mode. - select all images - then go to the UV image editor - image new -> set for width/hight one of: 64*64, 64*128, 32*128, 16*128, 8*256, 16*256 note: you can also interchange width and hight. e.g. 128*32 is also legal combination - bake - done Your sculptmap is calculated from the number of vertices

I have taken a very quick look into your blend file and: 1.) It is not 100% rotational symmetric, so you will probably have no big advantage from using the outline technique here. 2.) You try to achieve something that can not be done like you try to do it. The main problem is, that your object topology is massively diverging from the topology needed by sculpted prims. 3.) However there is one possible option how you can get away with your wheel: - create an oblong cylinder. - cut it into 9 pieces using the separation technique by collapsing vertices to a thin (invisible) line - Arrange the 8 inner spokes - Use the nineth subelement to create the rim. I hope that helps you a bit ? Hi, Feivl

First of all: <strong>Awesome work and one of my favorite sites ever! Perfect!</strong> But i have some problem with the technique in this tutorial. It`s easy to create the wineglas. But I tryed to draw some other things than the glas. My actual project is the wheel of a Segway. I have drawn the tire but after using the script "sculptify objects" I got an image with just 18 vertices on it. I imported the image as a sculpty and the result was just a naily undefinable object. What went wrong? Is there a max of vertices to use with this script? I can`t comprehend what the problem is. I love this method because I am free in my designs (I hate deforming the premodeled or imported sculptys :) I hope someone can help me with that... Sorry for my bad english! Best regards, Feivl Hi Gaia!

It is part of the standard Blender distribution so you should have it. The Blender "Empty" is just an empty object. You could start with that too. But then you would have to add an empty mesh to that object manually and i must admit that i do not know how i can add an empty mesh to an empty object... So your best option is just to use <code>add -> Mesh -> Empty Mesh</code> as explained in the video. The “Empty Mesh” with the Python Icon is exactly what you need.

The result of this step is the wineglas. Therefore you must be in top view when you start the spin tool and the end points of the line should have the same x,y coordinates and the cursor should be positioned at the same x,y positions too. Otherwise the rotation goes wrong and you end up with unexpected results (like holes at the top/bottom or completely messed structure when the rotaytion is not exactly around the z axis...)
