I just tried calling the OBJLoader method in both my client proxy and my model registry event. Neither fixes it. The Item in the inventory uses the correct model bu the block doesnt.

OH ok i see my problem i called the method to load obj models in the wrong event. Woops

Hello, I would like to load an obj model and use it as the model for a block. I have managed to get it to work for the item in the players inventory but i jst get a normal block with no texture when i place it in the world.

Hello again, I would like to know how to load a certain number of chunks around an entity/block. I need to be able to do this for an entity so that it can continue to do its work even if a player is not near by. I would also like to know if the amount of loaded chunks will effect the client or just the server.

Yeah i didnt explain that well. I remove all vanilla recipes so i know what tabs i have to remove. My question is can i test if a tab has recipes and if it doesnt remove it.

Yes i do. I remove all vanilla recipes. I was just hoping that if i add one of my items and its in a tab i wont have to change the code to account for that.

Ok i have gotten access to the list of tabs but now what? I know i have to remove the ones that have no recipes but is there a way to check if it has recipes? or do i just have to manually remove the ones that are not being used?

Hello, I seem to be having problems when ever i override all recipes in a tab. When i do this and i open the recipe book i get a null pointer exception. It seems to be be caused by the removal of the Lists of RecipeLists in RecipeBookClient.class. My question is is there a way i can fix this mayself or should i request a change some where? If i should request a change where would i do that.

Any ideas? Im really stumped on this.

Although i struggled to get the breakpoint to work or to view the variable i believe it is null because there are no recipes for some tabs. Do you have any idea why this is a problem or if it is even the actual problem.

I have tried the method that Choonster stated but i am getting a null pointer exception when i use the following code. @SubscribeEvent(priority = EventPriority.LOWEST) public static void removeRecipes(final RegistryEvent.Register<IRecipe> event) { if(ModConfig.overrides.recipes) { int recipesRemoved = 0; final IForgeRegistry<IRecipe> registry = ForgeRegistries.RECIPES; final List<IRecipe> toRemove = new ArrayList<>(); for(IRecipe recipe : registry) { if(recipe.getRegistryName().getResourceDomain().equals("minecraft")) { toRemove.add(recipe); recipesRemoved++; } } POverhaul.logInfo("Overriding " + recipesRemoved + " recipes with dummy recipes, " + "please ignore the following \"Dangerous alternative prefix\" warnings."); for(IRecipe recipe : toRemove) { final IRecipe replacement = new DummyRecipe().setRegistryName(recipe.getRegistryName()); registry.register(replacement); } } } and the error is: [18:06:36] [main/FATAL]: Reported exception thrown! net.minecraft.util.ReportedException: Updating screen events at net.minecraft.client.Minecraft.runTick(Minecraft.java:1879) ~[Minecraft.class:?] at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:1171) ~[Minecraft.class:?] at net.minecraft.client.Minecraft.run(Minecraft.java:436) [Minecraft.class:?] at net.minecraft.client.main.Main.main(Main.java:118) [Main.class:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_121] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_121] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_121] at java.lang.reflect.Method.invoke(Unknown Source) ~[?:1.8.0_121] at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) [launchwrapper-1.12.jar:?] at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.12.jar:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_121] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_121] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_121] at java.lang.reflect.Method.invoke(Unknown Source) ~[?:1.8.0_121] at net.minecraftforge.gradle.GradleStartCommon.launch(GradleStartCommon.java:97) [start/:?] at GradleStart.main(GradleStart.java:26) [start/:?] Caused by: java.lang.NullPointerException at net.minecraft.client.gui.recipebook.GuiButtonRecipeTab.func_193919_e(GuiButtonRecipeTab.java:146) ~[GuiButtonRecipeTab.class:?] at net.minecraft.client.gui.recipebook.GuiRecipeBook.func_193949_f(GuiRecipeBook.java:210) ~[GuiRecipeBook.class:?] at net.minecraft.client.gui.recipebook.GuiRecipeBook.func_193014_a(GuiRecipeBook.java:97) ~[GuiRecipeBook.class:?] at net.minecraft.client.gui.inventory.GuiCrafting.actionPerformed(GuiCrafting.java:142) ~[GuiCrafting.class:?] at net.minecraft.client.gui.GuiScreen.mouseClicked(GuiScreen.java:494) ~[GuiScreen.class:?] at net.minecraft.client.gui.inventory.GuiContainer.mouseClicked(GuiContainer.java:361) ~[GuiContainer.class:?] at net.minecraft.client.gui.inventory.GuiCrafting.mouseClicked(GuiCrafting.java:124) ~[GuiCrafting.class:?] at net.minecraft.client.gui.GuiScreen.handleMouseInput(GuiScreen.java:611) ~[GuiScreen.class:?] at net.minecraft.client.gui.GuiScreen.handleInput(GuiScreen.java:576) ~[GuiScreen.class:?] at net.minecraft.client.Minecraft.runTick(Minecraft.java:1866) ~[Minecraft.class:?] ... 15 more [18:06:36] [main/INFO] [STDOUT]: [net.minecraft.init.Bootstrap:printToSYSOUT:630]: ---- Minecraft Crash Report ---- // I let you down.

AL lib: (EE) alc_cleanup: 1 device not closed Edit: Is it deleting every recipe and that is why it is null? If so how do i only remove the vanilla recipes and not my own. Is there a specific way that i need to register my recipes so that they are not removed.

Ok then my final question is does that cause a performance difference? The errors that is.

Can i at least turn off the error notifications for it?

Is there a way to prevent this other than manually overriding each recipe.
