I need some help about the material

[FErD]

I want to use corona to make 'One side perspective glass' material .
This material looks glass from the front and mirrors from the reverse side, (Although it is not so simple

My idea is to use 2sidedmtl to make it. but,I didn't find this material in corona.

so,I want to know how to make this kind of material in corona.

I have an idea, what if you use multi sub-obj material.
1. create a glass material as usual, (I name it glass 1).
2. copy it to the second slot as the mirrorGlass.
3. use corona front/back texmap for mirrorGlass Fresnel IOR.
4. for the frontback texmap, set full black color at the front side and nearly white (which represent 1.5 fresnel) at the back side
5. set all object face mat ID to 1
6. set 1 object face mat iD you desired to 2

never tried this method, but who knows :)

If you don't need to use refraction and are just using a plane as your glass/mirror you can do it with one material. You would make a standard mirror material and then in your opacity slot you would put in the corona front/back map. with values like pure white and something like 130/130/130. (make sure clip is turned off for this one)

If you want regular glass refraction you will need two objects and materials. one a box for your glass and a plane for your mirror section. glass is just a regular glass material, but then the mirror plane is set up beside your glass and with a material as detailed above but with pure black and white.

That's probably the effect ....
1 faces, the front and the back are different materials.

Vray 2sidedmtl
but corona converter useless...
