VWR-4418 sculpted visuals, and parametric collision mesh in a single prim

Description

« Hide

It is not possible, to enter e.g. a sculpted cave. The avatar stops at the Bounding Box.
So several important applications of sculpties (found already five until now) are not possible without applying additional prims (fuzzy and expensive) to a phantom sculpt.
It's a great loss for the professional and commercial use of sculpties.

Personally, I would think that would fall under the 10 x 10 x 10 rule anyway. And I debate the great loss bit. You are the first I have heard of a sculpty cave. AS I read the forums, sculpties are heading for clothing, integration into building projects etc as components. It is extremely hard to alot of complex obiects out of sculpties with the constraints LL has on them. This is an oh well, add the extras prims.

Tomo – the challenge is to code collision heuristics that find the sweet spot between realism and server computational load. As you probably know, the current setting of that spot is weighted heavily towards minimizing server load so that sculpties do not cause noticeable lag.

To help make the best decisions on the future course of sculpties can you please list the specific applications (you mention five) that you believe suffer under the current simple collision model?

Thx

The simple bounding box collision detection is necessary (now at least) to keep sculpties lightweight objects for the server to handle.

bounding box? I thought it was a sphere of the same size (so even if the sculpty model has geometry outside of the sphere it is still a sphere of the same dimensions)
