I am working on updating my mod from 1.7.10 to 1.8.9. In 1.7 i had an inventory that can hold a single block and that block changes the look of the block to the one in the inventory. but with the new json rendering thing i have no idea about how to even touch this. if you can give me any information about how to get this done, I would be grateful.

TheGreyGhost has an MBE tutorial project (Minecraft By Example) for this specific mechanic, however, it is for 1.10.2, so you may need to improvise a bit yourself.
The tutorial can be found here: MBE04 | Dynamic Block Model

thanks, i will take a look, i had used his earlier example for 1.7.

 

i will see what i can do

This thread may also provide some information (and links to my code): 

 

I do something similar, where my tile entity can hold a camouflage upgrade item, and the block will render using that upgrade item's saved block state.
