HDRI visible on flat/Transparency objects, Plz help
I have scene with HDRI environment, but I have issue with the visibility of HDRI on the glass and flat objects
Its very reflected(looks like mirror). its also visible on some part of the body as you see in the image.
That's what I thought, material tweaks are needed. Standard Maya materials aren't suited for glass right out the box because the reflectivity is pretty constant regardless of the viewing angle, extra nodes are needed to simulate Fresnel reflections (like sampler info node), or you could use the mia_material_x, it behaves more realistically and even has a Fresnel reflections checkbox. Is there any reflection blurring on the phong/blinns? If not, then I can see why the reflections look crisp and strange.
Actually the mia_material has presets for glass, you could try one of those. If you have to use the Maya shaders then you could apply this method to their reflectivity channel.

How many methods to make glass in maya?
i'm a very beginner and i think there are some below ways:
1. use mia_material and preset to glass
2. use mia_material and use fresnel reflection checkbox
3. use dielectric_material
4. use blinn material and increase transparency value and decrease reflection.
please share some advice
I'd say 1 and 2 are the same deal, the glass presets use Fresnel reflections.
Using the samplerInfo node and a ramp(linked above) to control the blinn's reflectivity is another way but I don't see much point in it if you're using Mental Ray, the mia_material_x is more realistic and extremely versatile. I'd rather avoid the hassle.
