Problem with Nif Transparency

[PrometheusTS]

I have a weird problem , I have some meshes for wich I used alpha vertex color to get transparency on ground , the very same that is used on some snow drifts in vanilla nifs.

 

The BSlightningshaderproperty is actually the same , but this is the weird effect I get ingame.

The left is ingame, and as you can see the mesh of snow I created is transparent and showing background wooden stairs, while onright is how it should work as it appears in CK ...

 

What can be the issue here ? Any sugestions on how I could fix?

Thanks for any answer.

Here two sample files, the first is mine, and is transparent, the second is from Vanilla and is not transparent, I have checked both files and look almoust identical apart the shape and I can't find any reason why mine is transparent and the other not , I need some help here :( ....

Anyone?

Did you upload the correct nif? I tested it in my test worldspace and it did not look transparent. In fact it can't be transparent as the alpha is set to 1.0 and all the vertex alpha in vertex colors is set to 1.0, which is intransparent. In the vanilla snow mesh all vertex alpha have values below 1.0 so it should be half transparent but I did not see any difference in the transparency ingame.

the steps one is my mesh , the alpha is 1 on the centralparts of the bulk portions of snow and is 0 in the middle flat parts between the two bulks.

 

also the mesh uses the snowalt something , the one without the alpha in the channel I think?
