[1.14.4] Are stencils gone?

[LorenzoPapi]

I'm updating my mod to 1.14.4 and in 1.12.2 I used 

Minecraft.getInstance().getFramebuffer().isStencilEnabled()

and

Minecraft.getInstance().getFramebuffer().enableStencil()

, but I don't find them in 1.14.4 version and these two methods weren't used in vanilla in 1.12.2. Were they removed?

What are you trying to do? Due to the rendering changes in 1.15, I'd recommend rewriting your rendering code and re-assessing your approach to whatever you're doing completely.

I have a Java item model and I want to use it. In 1.12.2 I used the iChunUtil mod, but in 1.14.4 I don't know what to use. Since iChunUtil is open source, I saw the code and it used those methods you've seen up there. Is there a vanilla replacement?

Why are you using a Java model? There’s the ISTER system if you really need to render a Java model but you should definitely use the static model system OR load your model parts from files to support resource packs.

The fact is that in 1.12.2, my item changed colour of some parts depending on what the player was doing. Now I'm going to try the ISTER. Thanks!
