Render Bitmap tool. Adding area lights and line lights makes rendering very slow. If you add bluriness to a texture, it will make the rendering take longer as well. This has the effect of locking up your computer for 10 or 20 minutes at a time. This is not a great use of your time and it complicates decisions in regard of rendering. If you need help with textures, refer to the earlier workshop or kindle notes on textures.
You need to bring all these parts together, the rendering, lighting, textures and modeling. They all need to work together to make the view come alive. As you add textures, lights, background and models to the scene, Vectorworks starts taking longer to render the view.
