Makeing custom avatars is actualy kinda easy, but as was mentioned only you can see them...or your friends if you all have the same files.
My CC avatar is temporarily my FT avatar BTW. Heres how it looks with 4 pair in Omhama
The pics for the avatars need to be .png files 114x164 pixels with transparent backgrounds.
Find or draw a picture you want to use for your avatar. Resize it to 114x164. Use the selection tool in your editing program to select only the figure, ie the outline of your avatar. Copy that and past it on a new 114x164 .png file with transparent background.
Now Save it somewhere on your computer other than the avatar folders in FT.
Go to your fulltilt files, find: graphics/tables/avatars/public and pick one of the avatars, they are named 1 - 72. Wich ever one you pick is how you will look to the rest of fulltilt. Copy or move the pics in that file to a safe place incase you want to put them back in later.
Now inside one of the folders 1- 72 youll see four pics named 0-3, one for each emotion. You can make four emotions for your new avatar, just replace one, or make 4 differant avatars to use.
Paste your custom avatar in there and name it 0,1,2,or 3.
Now open your fulltilt software and log on. Try a playmoney table to see if your avatar looks good. If not, go back and do some editing. Note: you need to close and re-open fulltilt software everytime yu make a change to see the change...I dont know why.
The fun part...if you have a group of friends that all have custom avatars, share them with each other...just make sure you all pick a differant stock avatar, or emotion in the same one for your custom to go.
If this is confusing I can make a tutorial with pics if you think it wold help.
