Hello, I am totally new to the unreal engine.
I 've added some megascan grass, on and imported mesh, using the foliage tool and enabled the grass wind.
The problem is that the grass is animating in the z axis and it’s moving up and down like a wave. I guess this has to do with the wind direction.
How do I change the wind direction from Z to X or Y ?
I just checked some Megascans stuff, and there is no wind direction. I agree with you, by default, you only get to tweak the influence, and it does look weird.
Thing is, the main parameters are in a parameter collection. To get to that collection, go to the main material, double click the Simple_wind_material_functon, then double click on WindIntesity ( for instance ).
I found that setting ‘influence’ ( your original param ) on .5 and WindSpeed on 2 looks more real ( for the short grass ).

Thank you for your answer, but what I am looking for is to actually solve the problem.
The problem is twofold.
-
This old type of grass animation isn’t great
-
It’s up to the maker, how they code the animation into the world position offset.
So the solution is to re-code the material.

Here I have implemented a way to communicate the wind direction to foliages and bend them accordingly. They are not megascans. But still, you can modify the materials to get the effect.
