Light refraction and mirror effect rendering.
Hi,

I have downloaded a greenhouse 3D model on internet.

But I'm unable to render it correctly when I make a photo at the higher quality.

There are 2 problems:

- The surfaces have a too much pronounced mirror effect.

- The light changes direction when it passes throught the curved surfaces. So the objects in the greenhouse are displayed deformed.

Here is the .mtl definition of the transparent surface of the greenhouse:

newmtl Translucent_Glass_Blue.001
Ns 0.999999
Ka 1.000000 1.000000 1.000000
Kd 0.392157 0.584314 0.929412
Ks 0.000000 0.000000 0.000000
Ke 0.000000 0.000000 0.000000
Ni 1.000000
d 0.75
illum 1

I tried modifying it with various values, but it didn't solved my problems.

Does someone know:

- How to reduce the mirror effect of a surface ?

- How to reduce the deformation of objects inside or behind a curved transparent surface ?
