(Using latest Minecraft forge v10.12.0.1034).

I am registering textures in registerBlockIcons(IIconRegister), but in fact tests shows that it isn't invoked during initializations.

 

P.S. i see strange output in console, like forge trying to load mods from java's rt.jar file.

Experimentaly, i founded that following code works, but i think it is not the right way.

 

 

@SideOnly(Side.CLIENT)

public void invokeClientSetup()//invoke during Initialisation.

{

TextureMap iconRegister = Minecraft.getMinecraft().getTextureMapBlocks();

Minecraft.getMinecraft().getTextureManager().onResourceManagerReload(Minecraft.getMinecraft().getResourceManager()); //reload the atlas.

block1.registerBlockIcons(iconRegister);

block2.registerBlockIcons(iconRegister);

///.........

}

 

 

Maybe you've just included the wrong class in your header, for example there are multiple Block classes, only two of them are part of Minecraft.

For some reason cpw disabled this important reload {done after all loading has finished}

Next time I sync FML it'll be pulled in. For now you can either call cpw.mods.fml.common.FMLCommonHandler.updateResourcePackList() manually once in like.. post init. {But please only if your function hasnt already been called to prevent multiple mods reloading it}
