Mesh2 won't solve your problem. It is a different input format for the 
same object.

Working with mesh has a price: you have to pay it for what you want to do.
Solution would be either to not generate the offending triangles (if you 
can identify them easily...) or to give them a texture transmit of 1.

Also, beware of max_trace_level setting, default of 5 might be too low 
for some view point.

But why not use CSG with some boxes instead ?
Just updating the Irreg_Cube macro to one box instead of twelve 
triangles (it can take a little math to get the dimension of the box, 
and then the correct rotation and translation, but that shouldn't be too 
difficult). And then merge instead of mesh!
