lumion landscape grass issues

The landscape grass material applied to my imported topo model looks terrible recently. The blades of grass looks like a flat green rectangle sticking out of the ground.  Our office has a network license key and we have tried it on two computer and a laptop.  One computer is running on a Xeon x5687 and gtx 980ti 6gb. The other computer has an i7 6700 and Firepro 7100 8gb. The laptop has an i7 4710m and a gtx 980m 8gb.  All computer and laptop has 32gb to 64 gb of ram.  According to Lumion 6.3, the model we created is using 6gb of video card memory with 9.7 million 3D points and 276 Tress/plants. Settings for Trees and Grass are on high and the editing quality is on Super High Quality.  The graphics that we have should be sufficient to run this model but somehow the grass looks very bad in build mode and after it is rendered.  Please let us know what may be causing the grass to not show correctly in editor mode and in the rendered video.

Hi phanth

Thanks you the report.  From your description it is nothing to do with any of your PC's capabilities, they all sound quite capable for the Lumion Scene.

You're report is about the third time we have heard of this happening over the last 3 years.  Apologies.  What may have happened is the data for the terrain and 3D Grass has somehow corrupted, and this prevents the 3D Grass being generated correctly.  We have not yet been able to replicate the issue so it can be permanently fixed.

Does the grass look something similar to these:


or,



Do you know if the terrain and 3D Grass were first created using Lumion v6.0 or earlier version?

So that we can evaluate the issue, please send us an LS6 file Save Scene and Models.  Instructions here: HOW TO UPLOAD FILES FOR ERROR REPORTS.  You will need to register as per below to see this topic.

Unfortunately there is no simple easy way to reset/recover apart from repainting the terrain, unless you have a prior backup/older version where the 3D Grass shows correctly.

To repaint the terrain try this:
1. Turn off 3D Grass.
2. Repaint all the Terrain within the editable Lumion Terrain area ( a square 1000m x 1000m from center on X and Z axis) with the Terrain Paint Slot 1.
3. Then repaint the Terrain areas with any other Paint slots.
4. Turn 3D Grass back on.  Set the slot for the 3D Grass (usually Default Slot 1).

Does this fix the issue?
