This is the code to show an object in transparent mode inside a 3d scene.
if (getAnnots3D(pageNum).activated==false) getAnnots3D(this.pageNum).activated=true;var mesh=getAnnots3D(this.pageNum).context3D.scene.meshes.getByName("engine"); mesh.renderMode="transparent"
In my scene the object "engine" is very complex and I need to make it more transparent.
Is there some way to change the transparency level ? let´s say about a 20% of transparency...
A node object (meshes are nodes) in the 3D scene has an opacity property that you can set from 0 to 1.
