Edge Mode Shadows (Mental Ray)
« on: June 07, 2016, 03:46:45 PM »
I am using the "Wild Grass 01 (large)" preset.  I have used "Optimize Materials" to apply Forest Edge.  The grass is being clipped but the shadows do not look right.  It looks like the clipped grass is still casting a shadow.  Any ideas of what I am doing wrong?

Hi,

Which Shadows option are your light sources (sun / lights) using? The Shadow Map might produce similar artefacts, but Ray Traced Shadows / Adv. Ray Traced should render fine. Thanks in advance for any additional info and in case the issue persist even with ray-traced shadow types, please feel free to send us your scene. Thanks in advance.

Best regards,

Hi, the Wild preset used in your scene is not the same included with Forest, it has been modified: max file is "_fp_mental_wild_grass_field01.max", which doesn't exist in our library, and the material is a multi-sub with 20 materials, while the library has only 4.

Not sure what is causing the shadows issue, but i tried to reapply the preset from library and it renders correctly. Probably there is some problem with materials.

Please, do this:

1) Delete the Forest object.
2) Delete the objects "_library_5JUPFDQ__fp_wild_grass_01_clump_01", 02 and 03 from the "forest_templates" layer.
3) Create a new Forest, selecting the Wild grass preset from the library, and enable Edge mode.

That should solve the problem.

Thank you.  We keep our libraries on a shared server.  The grass preset library I was using must have been copied from an old version of Forest.
