I want to change named pumpkin texture and blur. I don't know now to change texture, beacuse pumpkin uses 3 textures, but I thinked I know now to change blur. There is the code and I don't know what I did wrong:
I'm not sure exactly what your problem actually is... Are you trying to retexture the GUI of the pumpkin? The blur? Or both? Are you trying to change what pumpkins are named ingame?
You can change the blur simply enough by retexturing the file:
If you're just making a simple resource pack, then you have to leave the file named pumpkinblur exactly, or it won't work.
If you want to rename it ingame without an anvil, you have to edit the Minecraft lang file.
If you want to edit the GUI for the item itself, that's a bit more complicated since pumpkins are 3D blocks.
Without further information, that's the best I can do, but I hope this helps.
