I have problem with lighting when I rotate model in TER. When it is rendered without rotation, lighting for up/down is correct, but all sides are bright. When I rotate it a bit, dark side (from bottom) is rendered on top. See picture where model is rotated ~90°

 

TES:

    public void render(WaterWheelTile tile, double x, double y, double z, float partialTicks, int destroyStage) {
        if (model == null) {
            model = Minecraft.getInstance().getModelManager().getModel(new ModelResourceLocation("toomanyores:waterwheel"));
        }

        Direction direction = tile.getBlockState().get(WaterWheelBlock.HORIZONTAL_FACING);

        GlStateManager.pushMatrix();

        GlStateManager.enableLighting();
        GlStateManager.translated(x, y, z);
        GlStateManager.scaled(1/16.0, 1/16.0, 1/16.0);
        GlStateManager.translated(8, 16, 8);

        switch (direction) {
            case NORTH:
                GlStateManager.rotated(90, 0, 1, 0);
                break;
            case SOUTH:
                GlStateManager.rotated(270, 0, 1, 0);
                break;
            case EAST:
                GlStateManager.rotated(180, 0, 1, 0);
                break;
            case WEST:
                GlStateManager.rotated(0, 0, 1, 0);
                break;
        }

        GlStateManager.translated(0, -8, 0);
        GlStateManager.rotated(90, 1, 0, 0);
        GlStateManager.translated(0, 8, 0);

        if (Minecraft.isAmbientOcclusionEnabled()) {
            GlStateManager.shadeModel(GL11.GL_SMOOTH);
        } else {
            GlStateManager.shadeModel(GL11.GL_FLAT);
        }

        int i = tile.getWorld().getCombinedLight(tile.getPos(), 0);
        int j = i % 65536;
        int k = i / 65536;
        float brightness = Math.max(j / 255f, k / 255f);

        bindTexture(AtlasTexture.LOCATION_BLOCKS_TEXTURE);
        Minecraft.getInstance().getBlockRendererDispatcher().getBlockModelRenderer().renderModelBrightness(model, tile.getBlockState(), brightness, true);

        GlStateManager.disableLighting();
        GlStateManager.popMatrix();
    }

 

Seems that 

GlStateManager.enableNormalize();
GlStateManager.enableRescaleNormal();

helped, but still there is visible effect that light is comming down in small angle not directly from obove.
