Information : The 3D grass is only available for Artlantis 2019.

Issue detected : You applied the 3D grass shader but you cannot see it in the final render.

General information: In the preview, due to software speed reasons, the 3D grass won't be displayed by Artlantis. It will simply color the surface giving it a brownish setting. The 3D grass will only be calculated in the final rendering.

Once the 3D grass applied, use the Zone Rendering tool to quickly calculate a part of the preview and check the way it will look in the final render.

Preview:                                                                                Final render:  

Cause of the issue : If the grass is still missing from the final render, it is very probable that faces were reversed in the modeler and the shader was applied on the negative side. Or, the Falloff setting is appropriate. 

How to solve it : 

1/ You'll need to change the orientation of these faces in the modeler: open your model in your modeler software and change the orientation of those faces you need. Save the file again and open it in Artlantis.  You can apply the Use Reference File... feature to recover your Artlantis edits. 

2/ You can use the Artlantis feature to change the orientation of faces: open the shader inspector and make a right click over the surface in the preview window. Choose: Reverse normals from the contextual menu. 

Please note that: 

- this function cannot be undone. 

- it wont be considered during a Reference file feature update either: the faces will become revered to their original orientation set in the modeler. 

3/ If grass is not displayed after rendering, please check that the distance of the "Falloff" in the shader inspector. The distance of the Fall off might be too small.
