I want to make some of the snow sparkle in the sun when looked at on a different angle like in EA's battlefront 2 , Possible or no ???

Not for terrain surfaces, no. Absolutely can with normal mesh surfaces, though.

ahhh okay then , I guess a solution would be to make very very tiny meshs - basically a particle, then make it glossy ? Although I would need thousands of those and I don' think that would work .

Thanks for the answer though.

Why would you make them tiny? Is this for snow falling from the sky or snow already on the ground? If on the ground, just the make the mesh(es) as big as it needs to be to cover the snowy areas of your terrain. And then to create the shiny gradient/sparkly effect, you would do that through the specular map texture (which most people seem to neglect for some reason).

This is a good idea but sadly It's a hoth map so all the area would have to be covered ... Im not sure how I would go about making a mesh that covers my entire terrain ... is it possible to import my terrain into softimage ???

I was saying tiny particles because then I could cover the ground with them.

Use a prop with the same texture as the floor, and then what Marth8880 said. You can place them in specific places I think it'd look cooler than the entire floor with that fx.

Here's some footage of Europa from MEU using modeled terrain with normal and specular map enabled: https://youtu.be/ByB4xup6i8Y?t=2071

Yes, this terrain was created in ZE, and imported/exported through XSI as a MSH file. And again, the icy/snow effect was done through the specular map texture (i.e. the black and white texture that goes in the alpha layer of both your diffuse and normal .tga files). Otherwise, the terrain would just have a flat shine to it.

Very interesting ! Thanks for the info
