Mesh House in SketchUp

[CompalSensei]

Sooo , i build a house in Sketchup and uploaded in Sl for try it ... But i don't know , when i tried to enter in house in door mostly it didn't let me like it was there a second door invisible ... Any one knows about that ?

The default collision (physics) shape is a convex hull of the low LOD of the uploaded mesh. By definition, it is impossible to get inside a convex hull, as it cannot include concavities or holes. To make a house you can go inside, you need to make a suitable phsyics shape. You do this on the physics tab of the uploader. However, getting physics shapes for buildings that work as expected and still have resonable physics weights (and thus reasonable LI) is not trivial. It generally requires using a specifically designed simplified phsycs mesh. There are many threads in this forum dealing with the details of different ways of doing this.

Can you explain this more easier please ? I'm not too fluent to english ....

Every model you upload has 4 versions; High polygon count model, a lower polygon count model, an even lower polygon count model, and the lowest possible polygon count model. These are called Level of Detail (LoD) models.

There is an additional model called the Physics Layer. The SL physics engine uses that model and only that model to calulate collisions. It is this model that determines whether or not an avatar can go inside the model. It is possible to turn off this layer by making the object non-physical. We then uses prims to control collisions. We make them inivisible.

If you allow the viewer to create the lower polygon count models and physics model, you tend to move toward a sphere. The viewer does a very poor job of creating the models and physics model. Most of us build all these models and upload them thus stopping the viewer from creating models we cannot control.

No one is going to explain how to create these models because we have already done that many times. Those posts are here in the forum. Search the forum to find them. I suggest you try searching in your native language. Also search YouTube in your native language and see if you can find tutorials.
