Basic Rendering Settings
Basic Render Settings
The Render Presets Manager will allow you to change the settings for rendering. Common adjustments are typically made to the Render Size, Current Preset, and Render Accuracy. Keep in mind, adjusting these settings can increase the time it takes to render. Also, the longer the render time, the more realistic the image will appear.
From the Render Presets Manager, you can render the image by clicking on the Render icon in the top right corner. For the first few renderings, you will want the size, preset, and accuracy low enough to create quick renderings to allow you to verify the lighting settings are correct.
The lighting settings can be changed by adjusting the AutoCAD Lighting Units variable. By typing LIGHTINGUNITS in the taskbar, then typing 1 and hitting enter, you change the setting to use American lighting units (foot-candles). Setting this variable to 2 will use international lighting units (lux).
Performing another quick render will determine if other settings need to be changed.
If the lighting still looks too bright, the Render Exposure setting can be adjusted. Typing RENDEREXPOSURE in the taskbar will open the Render Environment & Exposure window. Change the exposure higher will make the rendered image darker. Setting the exposure lower will make the image brighter. Make adjustments and perform quick renderings until the desired lighting effect is achieved.
Once all the lighting adjustments are sufficient, the render settings can be adjusted to give a more detailed and realistic image.
