Error:

[21:20:09] [Client thread/ERROR]: Using missing texture, unable to load geck:textures/blocks/concrete.png

Texture path:

forge172\src\main\resources\assets\geck\textures\blocks\concrete.png

 

Don't work even

class B extends Block {
  protected B(Material p_i45394_1_) {
    super(p_i45394_1_);
  } 	
}

@Subscribe
public void preInit(FMLPreInitializationEvent event) {
  Block b = new B(Material.rock).setBlockName("b").setBlockTextureName("geck:concrete").setCreativeTab(CreativeTabs.tabRedstone);
  GameRegistry.registerBlock(b, "b");
}

 

As i said, normal mods work fine with that textures.

Great! Thank you!
