materials for certain blocks/items?

[infinitephantasm]

while attempting to convert a map, i noticed a lack of certain blocks having materials, even after grabbing a resource pack:

cannot find material chest
cannot find material cobblestone_stairs
cannot find material redstone_wire
cannot find material vine

while some of these are less problematic than others (e.g. vine, maybe redstone wire), others, such as the chest & stairs (cobblestone stairs are not the only ones with issues, all stairs do not have textures in the pack i downloaded), i'm not sure how to make in texture form. since a chest has multiple pieces to it, due to it being a model, and since stairs are (assumingly) mapped texture-wise differently, how would that convert over to this program, being changed into a VTF?
