Hi.I dont know if this the right place to put my query or not, because below is the render of a MAYA file which I was working on for the lighting challenge. But now since the challenge is over I thought to put my question over here.
The render I am posting has been done in Maya & Mentalray with raytrace on. There is one light in the whole scene that is casting shadows and that is Point Light( if there are any other lights they have been added in layers and their visibility have been made off).
As you all can see in the render the shadows which are falling on the display case or tables (not floor to mention) are looking nice but any shadow falling on the floor casted by this point light is turning out a bit ugly.Infact the shadow of the woman seems to have two tones ,one dark black and other light gray.
I am going insane trying to figure out the reason for it and changing the values in attribute editor for point light and the raytrce values in render global window.
The current render uses following values:-
Render Global Window
The Max Trace Depth=1
Shadows=1

Attribute Editor (point light)
Light Radius=0
Shadow Ray=1
Ray Depth Limit=1

Plz help me solving this problem.Thanks

looks like you have a transparent floor and another plain one underneath ? Am i wrong?

No ,there is single poly plane ,which has been used for the floor. I have applied Blinn shader to it and then attached a jpg texture to the shader's color attribute.

Yes Lazzhar you are right. There are two overlapping surfaces in the floor of my scene. Out of which one is transparent.Thank you so much for solving my longstanding problem. I was actually going insane figuring out the reason for it:)
