I want to render a .json model file in the special renderer because I only need to add a water draining effect. The other part .json model doesn't really need to be specially rendered. Is there a way to do this easily or should I just make the model with the tessellator and gl.

Have you tried specifying the static model in the blockstates file as normal and then rendering the draining effect from your

TileEntitySpecialRenderer

?

Well you have the getRenderType function where you set the render type. If you choose TESR, the .json model doesn't render.

Block#getRenderType

is completely unrelated to

TESR

, except that returning -1 from it prevents the standard baked model from rendering. You should be able to have a baked model and a

TESR

for the same block.

So here's what I did to get "special rendering" with a json model, I'm sure there's an easier way but this works.

Just make sure you register the class instance of the event bus.

Choonster was right, after seeing i made a mistake registering the render it worked. Thanks to the both of you.
