I've created a custom fence gate and it renders in the inventory but not when placed:

 

ModFenceGate.java:

dark_nether_bricks_fence_gate.json:

http://pastebin.com/quzcajqd

 

Edit: Updated blockstate

 

Edit 2: I missed the powered tag and a , so it's now fixed

The blockstate needs to be a json - not java

Spelling mistake, it is a json file

Here is the error:

http://pastebin.com/L8tuUP0R

As you clearly can see in the blockste json, it does excist so what am I doing wrong?

I've missed the powered tag

Ok, thank you I guess. ..

I fixed it but it still says:

[09:26:29] [Client thread/ERROR] [FML]: Exception loading model for variant mm:nether_bricks_fence_gate#facing=south,in_wall=false,open=false,powered=false for blockstate "mm:nether_bricks_fence_gate[facing=south,in_wall=false,open=false,powered=false]"

what's the exception

How would I know that?

you posted the error that said there's an exception but didn't continue. post what was after those 2 lines because it tells you what the exception was.

Here is the full error:

http://pastebin.com/L8tuUP0R

hmm it still says it's missing variants, post the new json that you modified

I've updated the original post with the updated blockstate file

I noticed the exception is not for the model of mm:dark_nether_bricks_fence_gate but for mm:nether_bricks_fence_gate is that a change of name or another json?

 

in any way the error may not be for the block you posted in the first place

I have multiple gence gates: red_nether_bricks, nether_bricks and dark_nether_bricks

The top one in the error is for dark_nether_bricks_fence_gate and it still doesn't work

bump

Picture:

It's in that folder, it's just that I have so many so you can't see it on the Picture.

Since the error log says "file not found", we have to suspect some subtle spelling mistake in the file name(s). Show the part of the directory with those names. Did you add or drop an underscore?

Here is a picture:

I still need help!

bump

Can you just say what I should change

A missed a , so I added it and it worked!
