SECOND LIFE BUILDING OPTION

Import builds from easy-to-create

Google Sketchup  3D models

… at a (very) small cost

A demonstration in real time (9 minutes without preparation) of
how a 70 metre square can be created in SketchUp (using the
Sketchlife extension) from 10 metre square tiles, textured
using a single texture image spreading over all
the 49 tiles, and uploaded to Second Life.

West Australian Second Life resident Mrs Brandi ( EvgeniSergeev in his/her product details/YouTube publications)  has developed Sketchlife to allow Second Life residents  to create and upload builds/models using free, easy-to-learn Google SketchUp, a programme which is simple enough for it to be used regularly by primary school students in many New Zealand schools.

Created by University of Western Australia student “EvgeniSergeev”  ( is that a nom de guerre?) as part of the 2009 project for putting The University of Western Australia into Second Life , Sketchlife is being billed as an application that can convert 3D models made with Google Sketchup to Second Life through the use of an “importer” briefcase available free from the Mrs Brandi’s table at the university’s build in Second Life.

the Sketchup-import truck behind is free too.

“After winning Google’s ‘Build Your Campus in 3D Australia and New Zealand‘ competition ( in 2007, the models are on Google Earth) and also creating a VRML-based virtual campus with more detailed models,” Mrs Brandi explained to Wagner James Au of  NewWorldNotes, “we had about two dozen high-quality SketchUp models of buildings, and there was no easy way to put them into Second Life. That’s an island-full of buildings which are complete and textured, so it seemed worth the effort to write an importer.”

Hence Sketchlife, which, according to Au,  Brandi says is also useful for creating Second Life builds from scratch in Sketchup.

“Quite complex models could be built,” he/she said. “There is a limit of 512 prims per upload, to keep things sane (but if one needs more, they can be uploaded in multiple stages.)”

You can obtain the Sketchlife client for free from Mrs Brandi’s table in SL, though as with many but not all executables,  there is a price:  LS1 per primitive with no texture;  and L$2 per primitive with at least one texture. However, a model containing only one prim with at most one textured face can be imported for free allowing experimentation without one having to pay anything.

EvgeniSergeev explains in his product pages that  while  most 3D modelling tools use meshes (vertices connected by edges which define faces),  Second Life has adopted solids, referred to as primitives as their building blocks.

“This guarantees that there won’t be any stray polygons flying around, but it also prevents mesh models from being imported automatically,” he/she says, adding, however, that while  the in-world modelling tools in Second Life are quite good,  they are stone age compared to the 3D modelling power tool that is SketchUp.

“Therefore, if we can’t bring SketchUp to Second Life, we’ll bring Second Life to SketchUp.”

The video below shows  this happening: a very simple model of the words “Hello World” is built and uploaded using Sketchlife tools. It demonstrates the process: press “Export”, copy and paste the model key, drop the textures into the box, and, finally, copy and paste the build key. The process is the same for all models.
