Ok, two three things: 1) This particular error is found all the time, there's literally dozens of threads. A little searching would have gone a long way. 2) Yes, this error is huge and hard to understand, but it's because the main error ("unable to load model") can have multiple root causes: The file could be missing, it could be improperly formatted, be missing a key piece of data. The first error you see is only helpful in knowing "a problem exists with this item" you have to dig deeper to find out what caused that error. 3) The error you just posted is literally the same error you were just told to fix.

Learn to read your own damn errors.

Let me see here, of the core mods you have present... I've heard of these ones: IC2core (industrialcraft-2-2.7.81-ex111.jar) CCLCorePlugin (CodeChickenLib-1.11.2-3.0.0.298-universal.jar) CoFH Loading Plugin (CoFHCore-1.11.2-4.2.8.16-universal.jar) Inventory Tweaks Coremod (InventoryTweaks-1.62.jar) SoundFixPatchingLoader (AmbientSounds v2.1.2 mc1.11.2.jar) I can be pretty confident that these are not at fault: CCLCorePlugin (CodeChickenLib-1.11.2-3.0.0.298-universal.jar) CoFH Loading Plugin (CoFHCore-1.11.2-4.2.8.16-universal.jar) Inventory Tweaks Coremod (InventoryTweaks-1.62.jar) My suggestion is to remove all mods that are not the coremods, check to see if the problem persists. Regardless of the outcome you will perform a binary search to locate the mod at fault: 1) If the problem is present: remove half of the mods most recently added 2) If the problem is not present: add half of the mods most recently removed Repeat until adding/removing a single mod causes the issue.

I have a feeling most of your issues stem from the fact that you're using two blocks.

Why are you getting from and setting to the same inventory?

Postfix would made more sense: you're skipping the perfectly good ID 0.

Put transparency in the png image it's using as a source.

Gui.DrawRect doesn't draw "beveled" rectangles (octogons). It draws...rectangles.

Generally speaking, GUI images are premade textures. So you just... Create a png that looks like what you want...

You also never set a registry name for your block (and item). You also should set your unlocalized name to the registry name using getRegistryName() so that your mod ID is part of the unlocalized name to avoid naming conflicts with other mods.

Forge is, yes, but not Minecraft.

What's the crash?

Context?

What do you mean "rainbow"? What is your desired goal?

That link (and this thread) is 2 years old. The forum changed what software it runs on. This thread is for 1.7.10 is no longer supported here.

I don't think Forge will really be looking into it and answering those questions until 1.13 is final and out. They might have some ideas, based on looking at the snapshots, but no details yet.

*Looks at thread title* Hmmm

Yes. Because the ternary operation for 4 linear values (that map neatly to an index) is... Oh you said it before I did.

Post your model. Likely you want to use "parent": "block/cube_column" or "parent": "block/orientable"

You are adding new buttons every frame. 120 new buttons every second your gui is open. You want to update the buttons, then hold a reference TO the button and update it, don't create a new one.

Oh god why. ;_;

If you want to use textures like the log, perhaps you should look at the log?

Aaaaand your blockstate json file?

The field lookup is what's slow. Do that once, cache it. Actually retrieving the value is pretty fast.
