Pixelated mesh issue

[ReinaLexigle]

Hello to everyone

I'm facing a problem on my mesh , the mesh in question has hair alpha texture on it and its composed by a group of planes combined together in an order to avoid alpha blending issues.

here is a picture of my mesh rigged showing no problem .

but when rezzed in the ground it shows like picture bellow.

 

 

in your opinion what is the problem causing this ? the order combining my mesh ? or another problem
I heared about reordering vertices can help . Do you think the problem is because I did not reordered my vertices?

I checked that everything is ok on my model ,im using maya as programm and rigging in mayastar.

Hope to find a help thank you

How many triangles.

My first theory would be that your model is going over the maximum vertex index limit per mesh, and is being automatically split by the uploader "for your convenience" (but it never helps)

Second possibility is that it is an Alpha sorting issue.
