Fabric behavior to light
Posted: 31 Mar 2015, 20:23
Hello, hypothetically speaking, lets say that i want to create an image of a realistic sheet.
A sheet that just had been washed, so its hanging in a rope against sun, and its not ironed yet.
I noticed that im mising few things to achieve realism:
1)When the fabric is vertical against camera, or lets say between camera and sun -> fabric has max transparency.
When fabric has increased angles against the camera/sun , or when it goes like parallel , the fabric gets like zero transparency.
2)Also i noticed that shadows casted on the front side *(to the side where the light falls) appear on the back side too .
But on a simple test i did thats not happening by default:
How can i get these effects.
Just researching.
