Ok!! so one thing Im sure we have all noticed, or been warned about, is when you link a mesh to a sculpt the Land Impact (LI) has the potential to get very large. This has been fixed!
Ignoring scripts for the moment – if you link a sculpt to a mesh – the sculpt will have no more than 2 LI, and very often remain at 1 LI. Read this link and this is the portion of interest:
Changed prim accounting for legacy prims which use the new accounting system
- All legacy-style prims have their streaming cost capped at 1.0 (except for sculpts, which will be capped at 2.0). This provides the benefit of not penalizing prim-based creators for optimizing their content by opting into the new system and will make the streaming cost more reflective of the true network cost of the objects.
What does this mean? Well – I’ve experimented a bit and here is what I have found:
When I link a 1 prim sculpted bird to a 2 LI mesh birdhouse, I get an LI of 3.
How does this help a builder? You can make the chickadee sculpt in your name – so the build shows your name as creator with chickadee as root, and prim count does not go up (yes I know chickadee isnt root in this picture – but it does work with him as root!).
But sometimes the sculpt will jump from 1 prim to 2 LI – as in this case:
A 1 LI sculpt field:
When linked ads up to 3 LI:
Now 3 prims for a a field? Is that a lot? Well – this field is 8.5 x 8.5 meters, has 4 textureable plant faces (1 sculpt, 3 mesh) you can animate one of the mesh faces AND you have textureable ground cover. I think it looks pretty good for 3 Land Impact / Prim Equivalents.
So what does this mean for the builder? Experiment experiment experiment! You may be pleasantly surprised 🙂 I think these new changes give us some interesting options for combining prims, sculpts and meshes.
Hints: after the items are linked – try changing the root to “convex hull” on the features tab and changing the child to “none” – that should ensure that you have the lowest LI possible.
Also – check out this wikki post on physics optimization. Lots of handy information and a script to set all child prims to none!
I just made a new mesh bird house with plants. All in 2 prims! And I decided to put it up for sale at Creators Village at Builders Brewery. They are having a sidewalk sale and I nabbed a table. Builders Brewery has given me a lot – and I’ve learned so much from there. And most of my friends come from there – and now I even teach there! I make my students say “Rawr” when they are ready to continue… So anyway, I thought it would be fun to nab a table for the sidewalk sale. And a cut of my proceeds to go the Brewery – so win win!
The kit comes with the full perm mesh object. Which is 2 PE as delivered – and you can attach a small phantom prim as root and it will still be 2 prims AND have your name on the build. Add it to a build – add birdsong, add fluff – have fun! I’ve included some weathered wood textures, a grass with white flowers you can tint and an animated grass texture with script. You can have 5 different textures on the bird house and 3 different plant or grass textures – so go wild!
My table o’ stuff is at http://maps.secondlife.com/secondlife/Builders%20Resource/150/29/22 where you can come see it in the pixels.
Ive put this new fun meshy bird house for sale at 25% off or 375L – but only until 9 August. The sidewalk sale ends on August 9, and then I will put this for sale at my shop and marketplace and the price will be 500L
