Grass Height Issue

Hi,

i am developing a scenery for an airfield with a grass surface.
The issue i am facing is, that the grass height is not really changeable unless you change the colour (greener grass = higher height, grayish grass = lower height)
I tried choosing "Grass_Short Surface" in the Bit Map Editor but this didn't change anything.
On my airfield there are some ground markers that i created as a polygon and they can't be seen when i choose green grass, because it is too high...
Right now i am using Taxi_Grass but the colour of that is not really that good.
It would be really good to get a solution for that... Since there are options to choose between Grass_Erase, Grass_Short, Grass_High etc that should please change something!

Thank you

scenery

Hello.

We pushed a fix in SU6 regarding this.
The grass was supposed to be shorter in apron's vicinity but it was no longer working.
Apart from that, the height basically depends on how green it is so you can adjust the color to adjust the height.

Regards,
Sylvain

I wish i could say the fix was helpful. But (for me at least) it is still not working. Yes the height depends on the colour. That's what i recognized already, too. But since there is an option to choose between "Short_Grass", "Erase_Grass" etc. it should change something, what it does not, apparently.

And yes, you could change the colour of the grass but i tried it and the colour is awful as F when i get it to the correct height. (The height that usual lawn mown grass looks like)


Greetings,

Chris

As soon as I use an apron for this the grass completely disappears -> So you mean to change the color by changing the aerieal image?

That would really be nice to have a better influence on the grass height!

Before SU5 Update we worked with invisible apron stripes across the runway to lower the grass at 3U2 Johnson Creek, unfortenately this "workaround" doesn´t work anymore. Thats pretty bad for grass Airstrips due to the fact the "standard" grass is definately too high for a grass runway. So i definately support this request!

I have noticed that some users do not experience this grass which is too tall.

In scenery I have created, such as in the image of my previous post, I have seen videos where the same grass I have placed in the very same scenery is, on their pc, the correct height!

I have also noticed that these people have an AMD GPUs...

My theory at the moment is that it is only Nvidia cards that are affected with this grass height issue, it does not seem to be the case with AMD cards.

Also perhaps Asobo have AMD cards on their testing and building pc's, to be compatible with Xbox hardware...? and therefore may not be able see or reproduce this height abnormality...?

Is it possible somebody can confirm or deny this theory please?


Thanks

Mick

I really can't confirm that since i am using a Nvidia GPU.

But i can't imagine the GPU to be the problem.

The actual SU6 build fixed the problem with the grass height :)

What do you mean by "fixed"? How can it be influenced?

I think you are wrong. I just tested it and the issue still occurs. Not fixed yet!

Well all I can say is that people I know have sent me screenshots, those with AMD grass is normal, those with Nvidia grass too long...

The issue is still not fixed! Still experience the same issue with the grass height as before!

Asobo is in dire need to do something about this!

Please upvote this request so they will see it!

And what did you do to "control" the height?

We used a apron with the "Runway_Asphalt03" texture (0% opacity) and "force draw above runways"

Hello.

I got some more info on this.
As some of you suspected, the current behaviour in SU6 depends on your GPU. We just fixed a shader bug that will be available with SU7 and is causing some inconsistent behaviour with the grass.


That said, I also made sure we have a proper way to enforce a shorter grass:
- Create an apron
- Give it a material with a GRASS surface type (SHORT_GRASS and ERASE_GRASS are not supported and should be removed)
- Set opacity to 0 if you want to keep your aerial

The distance field is not very precise so there's a possibility it doesn't match perfectly the contour of your polygon.

Regards,
Sylvain
