Dimension Portal block have no transparency

Necromancer14, Can you elaborate? the texture already has transparency as I said, The dimension auto generates a block for the portal based on the texture I gave it, but I do not believe that the autogenerated block supports texture

So far ive tried adding transparency to the generated code in "DimensionPortalBlock.Java"

Which looked like this

@OnlyIn(Dist.CLIENT)
    public static void registerRenderLayer() {
        ItemBlockRenderTypes.setRenderLayer(ModName.BLOCKNAME, renderType -> renderType == RenderType.translucent());
    }

But this only returned an error in the dimension element.

Any help appreciated

Edit, I've imported the proper things into DimensionPortalBlock.Java,

Im getting the error

"error: cannot find symbol" 

at (ModName.BlockName)

                     ^

Dont know much about coding so sorry if this is a mess

Um Got it To work with no erros but its not transparent :(

Still Need help if anyone knows how to make the autogenerated block transparent
