I'm curious as to the best way to solidify, then hollow out a model built in sculptris. Generally when I've created an object, I've used several spheres, reshaping them as needed to get the look I want. I start the model in Sculptris, then port it over to Hexagon in order to change the size and do tweaks. The main issue comes when I've tried to hollow out an object. Using a wireframe view, I can see the overlapped parts of each sphere I've used in the model. Is there anyway to make the model one solid piece, getting rid of all those internal parts? I've tried several different methods, welding the whole model, or using boolean functions, but can't seem to get a satisfactory results. I'd really like to hollow out some of my models so the prices aren't as high for larger versions.
It should be noted that there doesn't seem to be an issue with using a model straight from Sculptris to Shapeways. I'm guessing that the models are viewed as completely solid masses. I've even tried hollowing out a model in Sculptris, but it's a very awkward process. I've attached an example to show what I'm talking about as far as the wireframes exported from Sculptris. There doesn't seem to be anyway, once I export the model from Sculptris, to choose the different parts of the model seperately. It's all viewed as a single model in Hexagon.
I do have access to Blender, but the interface on Hexagon is more friendly.

Step 1, grab yourself a free copy of NetFabb Basic
Step 2, use NetFabb to convert & save your model to stl format
Step 3, upload the stl to NetFabb Cloud Service - netfabb's cloud service does an excellent job of combing multiple shells into one - download the 'repaired' file.
Step 4, grab yourself a free copy of MeshLab and load in the 'repaired' file.
Step 5, In MeshLab use Filters (menu) -> Remeshing, simplification and reconstruction -> Uniform Mesh Resampling.
Step 6, In the dialogue box, check 'Absolute distance'. Set precision 'world units' to the required fineness of the internal mesh and set Offset 'world units' to your desired wall thickness. Click 'Apply'. Save the resulting generated meshes - there are 2 meshes, and inner and outer skin of your model.
Step 7, load the meshes into your favourite 3D model editor, remove the outer shell, load in your original model and combine/merge/flatten the shells/meshes/layers
Step 8, create a suitable sized tunnel and connect the two meshes.
Job done!
