Despite it being in a FMLClientSetupEvent, RenderTypeLookup does not seem to be modifying any of the blocks' render types.

 

    private void setup(final FMLClientSetupEvent event)
    {
        RenderTypeLookup.setRenderLayer(EarlyDaysRegistries.MOON_CREAM_BLOCK.get(), RenderType.getTranslucent());
    }

    public static final RegistryObject<Block> MOON_CREAM_BLOCK = BLOCKS.register("moon_cream_block",()->new SlimeBlock(AbstractBlock.Properties.create(Material.CLAY, MaterialColor.SAND).slipperiness(0.8F).sound(SoundType.SLIME).notSolid().variableOpacity()));

I have attempted this with other blocks as well with the same result.

As I am new to modding, I do not really know how to do this.

show your main class

@Mod("earlydays")
@Mod.EventBusSubscriber(modid = EarlyDays.MODID, bus = Mod.EventBusSubscriber.Bus.MOD)
public class EarlyDays
{
    public static final Logger LOGGER = LogManager.getLogger();
    public static final String MODID = "earlydays";
    public EarlyDays() {
        IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
        EarlyDaysRegistries.ITEMS.register(bus);
        EarlyDaysRegistries.BLOCKS.register(bus);
        EarlyDaysRegistries.TILE_ENTITY_TYPES.register(bus);
        MinecraftForge.EVENT_BUS.register(this);
    }
    @SubscribeEvent
    public static void onRegisterItems(final RegistryEvent.Register<Item> event){
        EarlyDaysRegistries.BLOCKS.getEntries().stream().map(RegistryObject::get).forEach(block -> {
            event.getRegistry().register(new BlockItem(block, new Item.Properties().group(EarlyDaysItemGroup.EARLY_DAYS)).setRegistryName(block.getRegistryName()));
        });
    }
    @SubscribeEvent
    public void setup(final FMLClientSetupEvent event)
    {
        RenderTypeLookup.setRenderLayer(EarlyDaysRegistries.MOON_CREAM_BLOCK.get(), RenderType.getTranslucent());
    }
}

I should have done that sooner perhaps.

Setting it to static worked. Thank you.
