| Bricks can be used to create fractional sculpties. A fractional sculptie is one single object which looks as if it where made out of two or more unconnected parts. But despite its look, it is still based on a regular sculpty mesh and all apparently isolated parts are connected to each other by “tiny tubes”. While you can see these connection lines in blender, they will go away once you have uploaded your sculptie to SL. | With Primstar-2 you can temporarily separate the fractions into detached Submeshes. See below for instructions how to do that.
The number of generated Bricks will be highly dependent on the settings of Width, Height, Depth and Subdivision Levels. As a rule of thumb you can say: The more bricks you get the less faces are available for each brick (because the total number of faces may never exceed 1024 for the entire sculptie !) |

Subdivision Levels and LOD |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fractional sculpting is very sensitive to LOD. If you do not take care here, your model will fall badly apart when you move your camera just a few meters away. So you have to take special care how to cut your object into fractions. Primstar-2 tries to optimize the fraction to always get the best possible LOD behaviour. The number of Subdivision levels is the key here! | Here is the mapping:

Once you have created your bricks array with a subdivision levels > 0 then you can temporarily separate the bricks as follows:
Hint: Also remind that the vertices are collapsed, so just right clicking does not work as expected. Use the border select tool instead! And ensure that “limit selection to visible” is DISABLED(!) Note that with Blender 2.4 this option was disabled by default, while with Blender 2.6 it is enabled by default. |

Hello Gaia,
What stitching type are bricks? Is there a reference as to stitching types to use for the other ‘Add Mesh’ items?
Thank you!
MG
In the properties panel, select the Cube icon for object, scroll down and open up the “Primitive Properties” section. The original mapping type is shown there (Cylinder for bricks), in object mode it’ll also show the LOD face counts for the sculpt map. The settings there don’t do anything yet, and it’s likely they will move into the 3D View properties panel when I code the primitive editing features that interface is for.
Hi, I am guessing you are very busy at the moment…but…I have left a couple of notes after the ‘texturizing sculpties I and II’ I am working with Blender 2.61 and the actions described in the vids don’t match with the newer blender. I have unwrapped all the surfaces and given them the textures I want (in both vids) and then I get lost. I can’t find a match to ‘consolidate into one image and from then on I am lost. I am building alot in blender and all my sculpts need multiple textures loaded onto them, it seems simple enough if i have the right actions. It’s such a crucial part of the link to sl, can you help please. Thanks
Hi, I have now moved table and chair to sl without the connecting tubes showing, I think it might be susceptible to over manipulation / modelling so I was alot more simplistic and careful about how all the sections connected.
Hi, I am able to successfully split the sections of the brick now and have modeled a 4 legged table using six bricks but when I bake and upload to second life the joining tubes between the 4 legs become visible. I have also made the same table by splitting a cube into sections and I still get the visible tubes in sl with a fair amount of distortion. Am I missing something in the process between finished model and sl.
ps. I have added a few edge loops to the sections and deleted the bricks I did not use.
Thanks Gaia,works great.
Hi, I am using Blender 2.60 and when I get to deleting the vertices between the bricks nothing happens, the vertices become unselected and remain in place, is there a different procedure for 2.60 ?
Hi, Tony;
thank you for the hint. I have updated the documentation and explain what is going wrong in your case (use border select and disable “limit selection to visible”)
