Exporting Materials from Rhino Properly

I’m attempting to export Rhino files into a different file format. I’m having trouble recreating the rendering in Rhino, however, when I have to export blocks of objects. If the objects have had materials assigned to them before becoming a block, then when I export I will either get the default material (if I set the material of the block to object) or I will get a the layer material. It would make sense to me that objects pertaining to the same block would have to be the same material, but this isn’t what is rendered in Rhino. Am I exporting these objects correctly is there a way of going about it that will match the rhino rendering?

I’ve attached a sample scene that I tried to export from Rhino where you can see the problem that I am experiencing. (The objects with the label “block” are in a block and in Rhino are set to have the material of the layer which is the 3D checkered texture you see in the exported image.) Any input would be greatly appreciated. Thanks!
