this is the luxball5 scene i remodeled in rhino for the luxrender community.
the scene is just seted, check the unit scale. maybe Abel could help in checking this.
inside you can find the light planes and the illumination i did to be used with an hdr.
the luxrender numerical grid, the bubbles are inside as meshes, on different layers.
the metric textures can be find here
enjoy and thank you for the great job on the exporter
