Grass in FG

[Foxtrot15]

Hi,

I read somewhere in the wiki that 3.6 has 3d grass. Interestingly, neither 3.6, 3.7 nor 16.0 has 3d grass with rendering maxed out.

Did I read wrongly?

You have to uncomment the lines for volumetric grass in the materials file. I didn't find a way to make it look good with Rembrandt or default on, so I didn't simply want to spoil things for non-ALS users.

sounds like materials.xml might benefit from supporting XML conditions, or does it already ?

[Thorsten]

They do, but random vegetation is an effect declared on top of that and effects do not support the standard conditions (they do support predicates). Since grass runs over what is in essence the normal tree effect, disabling it when Rembrandt is running kills all the trees.

I suppose with enough determination it can be hacked into something that actually switches, but then it's also a performance-critical thing,...

Which materials.xml file ?

No longer needed, in the shader settings you need "Wind Effects" enabled and "Overlay" enabled and a graphics card that supports geometry shaders.

I'm not sure which all helicopters support it, but for sure the AirCrane supports grass rotor wash as well to help test if it is working for you.
