I made a custom gungan but its ears are messed up and they drag to the ground i copied all the code from the gungan but changed the weapon also it has all the tenticle code

You perhaps forgot to copy the munged files from assets\sides\gun\munged to your mod\sides\gun\munged

i did that still did not work

EDIT
Does anybody know what i could do

When I get home in about an hour I will see if I can help. I almost guarantee this is a skeleton issue... vertices that can't find the bone that they are enveloped to will default to the unit's root (coordinate 0,0,0). This causes the funny stretching-to-the-ground effect.

also he moves really slow and it always says he has fleed when i havent even done anything with him

What other files have you changed aside from that Gungan's odf?
Can you please post the contents of his odf file?

Make sure you have the cloth set up correctly. Do you have Darth Vader's cape odf in your side folder? Have you hex edited the cloth from Vader onto the gungan model? Because you need to do both of those things.

i took of vaders coat and the gun gan looks fine now with no problems but i really want to have the coat so how would i do that i had that thing i had in there but it didnt really work

Go to the FAQ thread and read one of the tutorials on hexediting capes from existing models.

i went to the faq i dont see anything about hexediting capes from existing models is it the one about the BF1 cape to BF2
