In this Video, Daniel Hargreaves of AccuStudio will show you how to use the lighting defaults to create basic lighting conditions for nXtRender while rendering your AutoCAD drawings.
Lighting Defaults make it easy to set the lighting parameters for interior scenes, exterior scenes, or to chose studio for rendering of individual objects without having to know a lot about the details of lighting settings

Lighting Basics Tutorial
Step 1 - Download Model
- Download model from: AccuStudio
- Load the model into AutoCAD and start nXt
Step 2 - Add a Ground Plane
- Go to the Widget icon and select Groundplane.
- You'll be able to put a plane under your model.
-
Step 3 - Render with Studio Lighting
- Click the double Down Arrow on the Lighting Tab to expand the tab.
- There are 4 preset lighting choices - Studio, Exterior, Daylight and Interior Lighting - select Studio.
Click the green car to start the rendering.
Let it run for about 100 passes.
Notice the subtle shadows under the eaves and on the ground.
Step 4 - Change the lighting to exterior
This is a single source of light like the sun lets you change azimuth and altitude. We're going to stay with the default.
Click the green car and let the rendering run for about fifty passes.
We will explore the other two settings - Interior Daylight and Interior Lighting -
in another Tutorial. They work best for interior scenes with interior lights.
Step 5 - Use Model colors
Now let's explore changing the model to use model colors and studio lights
Go to the render setting, click on the double down arrow, scroll to the bottom
and put a check mark nest to Use object color.
Go back to lighting, make sure studio lighting is set, and
click the green car to begin the rendering process
Instead of an all-white model, nXtRender has loaded layer colors into the model. It will take more passes to get a good rendering with colors.
Let it run for about 200 passes.
Notice that the background is in white. This is because the model colors respond to the lighting.
