Well, it seems that normals doesn't get rotated with the model itself when I use GlStateManager.rotate.

I have a JSON model. One part of it is static, and two parts are dynamic. Dynamic parts are rendered using TESR. If the facing of model placed in world is NORTH (default) - everything is rendering as it should, but when model gets rotated, static part is rendered fine and TESR part looks like normals of dynamic parts are still pointing to the NORTH direction. Here are the screenshots:

Model facing SOUTH

 

Model facing NORTH

 

TESR rendering part:

@Override
public void render(CounterTE te, double x, double y, double z, float partialTicks, int destroyStage, float alpha) {
    GlStateManager.pushAttrib();
    GlStateManager.pushMatrix();


    GlStateManager.translate(x, y, z);
    GlStateManager.disableRescaleNormal();

    renderDoor(te, partialTicks);

    GlStateManager.popMatrix();
    GlStateManager.popAttrib();
}

public void renderDoor(CounterTE te, float partialTicks) {
    GlStateManager.pushMatrix();
    RenderHelper.disableStandardItemLighting();

    this.bindTexture(TextureMap.LOCATION_BLOCKS_TEXTURE);
    if (Minecraft.isAmbientOcclusionEnabled()) {
        GlStateManager.shadeModel(GL11.GL_SMOOTH);
    } else {
        GlStateManager.shadeModel(GL11.GL_FLAT);
    }

    World world = te.getWorld();
    //Rotate renderer to match FACING
    
    GlStateManager.translate(.5F, 0, .5F);
    if(world.getBlockState(te.getPos()).getValue(CommonBlock.FACING) == EnumFacing.NORTH)GlStateManager.rotate(0, 0, 1, 0);
    if(world.getBlockState(te.getPos()).getValue(CommonBlock.FACING) == EnumFacing.EAST)GlStateManager.rotate(270, 0, 1, 0);
    if(world.getBlockState(te.getPos()).getValue(CommonBlock.FACING) == EnumFacing.SOUTH)GlStateManager.rotate(180, 0, 1, 0);
    if(world.getBlockState(te.getPos()).getValue(CommonBlock.FACING) == EnumFacing.WEST)GlStateManager.rotate(90, 0, 1, 0);
    GlStateManager.translate(-.5F, 0, -.5F);

    Tessellator tessellator = Tessellator.getInstance();
    BufferBuilder bufferBuilder = tessellator.getBuffer();
    bufferBuilder.begin(GL11.GL_QUADS, DefaultVertexFormats.BLOCK);
    
    IBlockState stateLeft = NMFBlocks.counter.getDefaultState().withProperty(Counter.ASKFOR_LEFTDOOR, true);
    IBlockState stateRight = NMFBlocks.counter.getDefaultState().withProperty(Counter.ASKFOR_RIGHTDOOR, true);
    BlockRendererDispatcher dispatcher = Minecraft.getMinecraft().getBlockRendererDispatcher();

    IBakedModel modelLeft = dispatcher.getModelForState(stateLeft);
    IBakedModel modelRight = dispatcher.getModelForState(stateRight);

    GlStateManager.pushMatrix();
    //Render LEFT door
    GlStateManager.translate(0.96875F, 0, 0.15625F);

    if(te.getMovingDelta() != 0)
        GlStateManager.rotate(-(te.getOpenProgress() + partialTicks * ((te.getMovingDelta() > 0) ? 1 : -1)), 0, 1, 0);
    else
        GlStateManager.rotate(-te.getOpenProgress(), 0, 1, 0);
    GlStateManager.translate(-0.96875F, 0, -0.15625F);

    GlStateManager.translate(-te.getPos().getX(), -te.getPos().getY(), -te.getPos().getZ());

    dispatcher.getBlockModelRenderer().renderModel(world, modelLeft, stateLeft, te.getPos(), bufferBuilder, true);
    tessellator.draw();

    GlStateManager.translate(te.getPos().getX(), te.getPos().getY(), te.getPos().getZ());
    GlStateManager.popMatrix();

    GlStateManager.pushMatrix();
    //Render RIGHT door
    bufferBuilder.begin(GL11.GL_QUADS, DefaultVertexFormats.BLOCK);

    GlStateManager.translate(0.03125F, 0, 0.15625F);
    if(te.getMovingDelta() != 0)
        GlStateManager.rotate(te.getOpenProgress() + partialTicks * ((te.getMovingDelta() > 0) ? 1 : -1), 0, 1, 0);
    else
        GlStateManager.rotate(te.getOpenProgress(), 0, 1, 0);
    GlStateManager.translate(-0.03125F, 0, -0.15625F);

    GlStateManager.translate(-te.getPos().getX(), -te.getPos().getY(), -te.getPos().getZ());

    dispatcher.getBlockModelRenderer().renderModel(world, modelRight, stateRight, te.getPos(), bufferBuilder, true);
    bufferBuilder.putNormal(0F, 1F, 0F);
    tessellator.draw();

    GlStateManager.translate(te.getPos().getX(), te.getPos().getY(), te.getPos().getZ());
    GlStateManager.popMatrix();

    RenderHelper.enableStandardItemLighting();
    GlStateManager.popMatrix();
}

 

TESR is necessary because of block inventory rendering. That's actually the only reason why I don't use ASM animation...

Ah, nevermind. I've just changed IBlockState(s) for models to match FACING as well and removed rotation part from code. That fixed the lighting issue, so I'm happy
