I want to add lot metals to minecraft I want to make one ingot texture and them tint it for each metal, for ores i want to get even more complicated, for this I want to overlay the stone texture with an ore texture that has already been tinted, some ore I want to spawn in multiple dimension so for nether it would be netherrack overlay with ore texture, but i want this to stack overworld ore of the same time type (i do not mind if ore mind in the overworld then takes on the neterrack texture in nether.

 

I so what i would like know relay is there any easy to pass in image as texture and not a location to in the jar.

 

Also to make textures change depending on what dimension the player is in.

 

This might be overkill, but here's a TextureAtlasSprite class I use to smash two textures together (and allows for colorization as well).  You should be able to make use of it for your ore blocks at least.  Colorization is a hue alteration on the HSV spectrum (retains the desired grayscale contrast better).

Do be aware that any loading problems don't have their errors handled nicely.  Vanilla's TextureAtlasSprite class will go "I couldn't find resource x:y" this class will just vomit a stack trace.
