Job: Ores and Nodes 3D Model

Hello I am in need of ores and nodes. Essentially I am building a mining script for my server. I understand the budget is tight, so I am only asking for 2 models.

1 model for the node that they hit and then a model for the ore that is given when hitting the node. The images below are not to scale obviously.

I require absolutely that the models have sub materials that strictly are used to draw the ore part of the rocks. For example having all the veins on one material and then having all the ore portions on one material then the rest on a stone material. Hopefully that makes sense. Just think of it as allowing me to color coordinate based on ores while only using 2 models. This might be a little confusing, for I'm not the best at explaining it, so please feel free to ask any questions.

For the nodes think similar to:

For the ore think similar to:
