I increased the block limit for Minecraft to 4096.  Here is the Forge version.

This comes with a test mod that tests the block limit.  Tell me if this is useful or not.

 

EDIT:  Install this into your Minecraft with Forge already installed.

Do we add the file right into Minecraft .jar with Forge already installed, or do we edit our current version of Forge?

Yeah, add it right into your minecraft.jar with Forge already installed.  Sorry I didn't specify.  Been kinda busy.

Minecraft loads fine when I add the file to my .jar - Forge recongizes the mod as mod_test.

 

But when I try to add a mod that gives the game more blocks (I was already at the 256 limit before installing, I receive this error

Its pretty much the same error I've been getting when I try to add mods that add blocks. The mod I'm adding is called Netherrocks, and its the Client Forge version. All the mods I'm using are compatible with Forge. The current forge version that I'm using is 3.2.5.120.

You get that error because 2 mods use the same block/item ID on a certain block.  Easy fix is remove the mod that adds the BlockTrellis.  Just because more IDs exist doesn't mean all mods will get along.  The problem is my code fix just came out and no one has created mods that use higher IDs.  This is a problem until the mod authors or a 3rd party fix it.  Sorry to tell you that.

Ah, no worries. Thanks for explaining.

1) Nobody use this as I haven't verified what it doesn't and it does break old worlds.

2) Forge ALREADY supports 4096 in a better fashion

3) If its something important you should submit a PR to forge, not release 'custom builds' as that's just fucking stupid.
