Vein Resource Data Assets Are Missing Terrain Material & Noise

[OurLordAndSaviorGabeNewell]

Vein Resource Data assets are missing their respective terrain material specification, so when the game attempts to generate a custom vein it causes a crash.

RES_VEIN_Nitra asset uses TM_Nitra for it's Terrain Material. RES_VEIN_Gold uses TM_Gold, so on and so forth.

RES_VEIN_Nitra asset is missing the noise specification of Noise_GOld, this is not the noise value under CSG Triangle Mapper.
