Is there anyway to set to the out put for that second life plugin for this or within the program itself to be 512 instead of 64x64?
I tried looking but I just couldnt figure it out. |

There's no user-configurable option to do so. Technically speaking, Second Life won't use a sculpt map above 32x32, as this already results in 1024 vertices in the mesh... as much as a torus, which is the other heaviest shape. At a distance, SL drops the resolution to 16x16, or 256 vertices. The maps generated by the exporter are at 64x64--even though SL can't actually render this--by recommendation of Qarl Linden. I assume this is both for future-proofing and to get a little bit of oversampling to hide the artifacts. A 512 map would be over a quarter of a million vertices, way too much for the SL renderer to handle even if they'd let you; and ironically, it will still have artifacts, as the issue is the limited numerical precision, not the texture resolution.
![]() For what it's worth, internally the plug-in actually renders the image at a higher resolution and downsamples it to 64x64 to smooth the output. Just curious, what are you wanting to do with a 512 map? |

I was just hoping to get tighter detail to show up on the sculpt on the prims. I do a lot of detailed work and so much is lost. Thanks for the reply too.

Ah, gotcha. I think more detail is a big wish for a lot of people. :-) I wonder if there's a JIRA entry for more bits per channel?
Depending on your model, you can sometimes get more detail out of them if you adjust with the UV map. Since the AC3D plug-in renders the sculpty in texture space, if you increase the texture space of an area, you will get more vertices devoted to the area in the final sculpty. Select the surfaces you want to get more vertices devoted to, then go into the texture coordinate editor and stretch that section of the map to make it larger. |

Here's an example showing the *dramatic* difference adjusting your UV map can make.
The images show: the original test shape in AC3D, the default UV map, the UV map after adjusting to protect the "nose" of the sphere, and the radical difference in output when the two versions are rendered in Second Life. (Original uv map is on top, adjusted uv map is on the bottom) |

Hey Lisa,
You seem to be the Second Life Pro here... ![]() Below is a bike I did using sculpts created in AC3D for the Tank, Handle bars, Seat, and the exhaust pipes.... |

Thanks so much for the reply and information. I'll give it a try and hopefully put it to good use! :grin:
