FSXA Edge Grass transparency Issue

[JPetroSS]

Hello guys once again.

I'm facing this issue now that lies on the edge grass texture I'm using.
The transparency I've used is "visible" on top of the groundPoly and it seems like it is excluding it.

I have used a vertically lofted line in order to create the grass.

The parameters are:

Set default transparent

Z-Test Alpha: checked

Alpha test level: 128

Alpha test mode: GreaterEqual

Z-write Alpha: checked

Double sided: checked

Can I do something for this?

Thanks a lot!

Peter

Looks to me that the ground poly is at a higher elevation than the grass (look at the right edge of the ground poly).

What does it look like from an overhead view?

Ground poly has less priority to be seen less than any FSX MDL.
What I do is export those grass as another layer of ground poly. No mater it is vertical shape no flat like ground.

You can use MCX just to follow this thread. http://www.fsdeveloper.com/forum/threads/filter-out-non-ground-polygon.425396/page-2

To summarize this thread when you use MCX to make ground poly, un-check all the boxes out.

Thank you guys.

I wanted to place the ground polygon as a layer on top of all other layer, using the ground polygon wizard.
That's what I usually do, but this time the ground poly appeared cracked and broken, so I slightly elevated it and placed it as an MDL object on top of all layers.

My ground poly is a 4096x4096 Plane object with Alpha.

By the way, what's the correct way to place a ground polygon ?

If it appears broken, it is most likely a flatten issue. Try adding another flatten polygon covering this area and some extra area around it. Then layer the ground polygons as usual.

The correct way to place a ground polygon is whatever works...

That's exactly what I think too.

In another airport of mine, this method worked perfectly.
However, this time the airport is on a hill and its a bit more complex flattening the area.

Here's what I did in Gmax.

Thank you so much, jtanabodee!!

I tried your trick in MCX and it worked fine for me but....the grass is only visible from the left side. When I look at it from its right side its invisible.
Do you know why this happened? I have checked the double-sided box in the material menu.

Thanks again,

Petros

I don't know what cause that. If you have problem you can clone the polygon and use the function flip then you will have double side polygons.
