Entity not rendering

The entity creates a pillar of blocks. It appears to work fine; the blocks are getting placed. But the entity is not rendering. It should be displaying interpolated movement upwards. Instead, the blocks just appear (so the entity is invisible).

    public void tick() {
        LogManager.getLogger().info("ticks: " + ticks++ + " current " + blockPosition() + " old " + oldPos);
        if(blockPosition().equals(endBlockPos)){
            if(releaseJutsuOnce != null){
                releaseJutsuOnce.execute();
            }
            remove();
            return;
        }
        if(blockPosition().equals(oldPos.above())){
            oldPos = blockPosition();
            level.setBlockAndUpdate(blockPosition(), blockState);
        }
        setDeltaMovement(0, 0.1, 0);
        move(MoverType.SELF, getDeltaMovement());
    }

Renderer (copied from falling block):

public class MudWallBlockEntityRenderer extends EntityRenderer<MudWallBlockEntity> {
    public MudWallBlockEntityRenderer(EntityRendererManager entityRendererManager) {
        super(entityRendererManager);
        this.shadowRadius = 0.5F;
    }

    @Override
    public void render(MudWallBlockEntity entity, float entityYaw, float partialTicks, MatrixStack matrixStack, IRenderTypeBuffer buffer, int packedLight) {
        BlockState blockstate = entity.getBlockState();
        if (blockstate.getRenderShape() == BlockRenderType.MODEL) {
            World world = entity.getCommandSenderWorld();
            if (blockstate != world.getBlockState(entity.blockPosition()) && blockstate.getRenderShape() != BlockRenderType.INVISIBLE) {
                matrixStack.pushPose();
                BlockPos blockpos = new BlockPos(entity.getX(), entity.getBoundingBox().maxY, entity.getZ());
                matrixStack.translate(-0.5D, 0.0D, -0.5D);
                BlockRendererDispatcher blockrendererdispatcher = Minecraft.getInstance().getBlockRenderer();
                for (net.minecraft.client.renderer.RenderType type : net.minecraft.client.renderer.RenderType.chunkBufferLayers()) {
                    if (RenderTypeLookup.canRenderInLayer(blockstate, type)) {
                        net.minecraftforge.client.ForgeHooksClient.setRenderLayer(type);
                        blockrendererdispatcher.getModelRenderer().tesselateBlock(world, blockrendererdispatcher.getBlockModel(blockstate), blockstate, blockpos, matrixStack, buffer.getBuffer(type), false, new Random(), blockstate.getSeed(entity.getStartingBlockPos()), OverlayTexture.NO_OVERLAY);
                    }
                }
                net.minecraftforge.client.ForgeHooksClient.setRenderLayer(null);
                matrixStack.popPose();
                super.render(entity, entityYaw, partialTicks, matrixStack, buffer, packedLight);
            }
        }
    }

    @Override
    public ResourceLocation getTextureLocation(MudWallBlockEntity pEntity) {
        return AtlasTexture.LOCATION_BLOCKS;
    }
}

Registration:

RenderingRegistry.registerEntityRenderingHandler(ModEntities.MUD_WALL_BLOCK_ENTITY.get(), MudWallBlockEntityRenderer::new);

This is not at all the correct usage for @OnlyIn. Yes, @OnlyIn does cause issues. Do not use it.

I will create my own annotation for marking things. It is better than using a comment. It would be interesting if I could somehow intercept method calls for methods annotated with it, and check the side. I am not sure If I can do that with my limited java expertise.
