Poor ores, Ores and Dense Ores (Contenttweaker) generate with Rendering issues

[Ethryan]

Hi,
when I use the materialsystem to add ores. Beacon beams, the breaking animation and rain, have issues for me that makes them unuseable, since you are able to see straight through the block during breaking.

code responsible for the creation of the blocks:
for material in oreSampleMaterials {
var poorOreData as MaterialPartData = material.registerPart("poor_ore").getData();
poorOreData.addDataValue("drops", oreDrops[material]);
poorOreData.addDataValue("variants", "minecraft:stone");
poorOreData.addDataValue("hardness", "5");
poorOreData.addDataValue("harvestTool", "pickaxe");
poorOreData.addDataValue("resistance", "15");
poorOreData.addDataValue("harvestLevel", "1");
}

for material in oreSampleMaterials {
var oreData as MaterialPartData = material.registerPart("ore").getData();
oreData.addDataValue("drops", oreDrops[material]);
oreData.addDataValue("variants", "minecraft:stone");
oreData.addDataValue("hardness", "5");
oreData.addDataValue("resistance", "15");
oreData.addDataValue("harvestTool", "pickaxe");
oreData.addDataValue("harvestLevel", "1");
}

for material in oreSampleMaterials {
var denseOreData as MaterialPartData = material.registerPart("dense_ore").getData();
denseOreData.addDataValue("drops", oreDrops[material]);
denseOreData.addDataValue("variants", "minecraft:stone");
denseOreData.addDataValue("hardness", "5");
denseOreData.addDataValue("resistance", "15");
denseOreData.addDataValue("harvestTool", "pickaxe");
denseOreData.addDataValue("harvestLevel", "1");
}

Is there any way to fix this problem?
Or is this related to the #111 issue?

A simple workaround would be - use materials for everything except the ore and a normal block with weighted drops instead of the broken generated one.
