Where are the landscape objects for AutoCAD 3D render?

A - answer With the change of the rendering engine in AutoCAD 2007 (and higher) the special "landscape" objects (trees, shrubs, cars, people..) are no longer available (the former LSNEW, LSLIB commands).

There are some workarounds for adding entourage objects to your 3D scenes for rendering:

  • Use full 3D models of entourage objects - see e.g. the Block library
  • Add the entourage pictures only as 2D images to the rendered picture (postprocessing in Photoshop)
  • Use an alternative rendering tool - e.g. 3ds Max, Piranesi...
  • Use the simplified, render-ready RPC objects from ArchVision - see their offering to AutoCAD users.
  • Make simplified (planar, crossed) models with materials using texture maps and opacity maps (orient them to your camera) - see below

How to add opacity-based planar models to your scene for rendering:

  • Run the MATERIALS editor.
  • In the Materials tool palette, click "Create new material" and name it.
  • In the Template drop-down list, select Advanced.
  • Select the Diffuse Map check box.
  • Select Texture Map from the drop-down list.
  • Click the "Select Image" button and select the image you want to use for your entourage object (tree, people...).
  • In the "Material Scaling" section, set the "Scale units" to "Fit to Gizmo" and set U and V tile to 1.00 (in version 2007: Adjust Bitmap > Bitmap Scale > Fit to object).
  • In the Opacity section, click "Select Image", and then browse to a opacity image file (black will not show, white will show the diffuse map image).
  • In the "Material Scaling" section, set the "Scale units" to "Fit to Gizmo" and set U and V tile to 1.00 (in version 2007: Adjust Bitmap > Bitmap Scale > Fit to object).
  • And finally - create a 3D face in your DWG scene and apply the new material to it. Now you can render the drawing.
