Mental Ray Lighting

I followed a video tutorial to learn how to use Mental ray lighting,
As before I used a scene from last semester, opened up the rendering window, and assigned ‘mental ray renderer’ as the production render as before.

I dragged out a spot light onto the scene and positioned it over the Easter eggs, and also i turned on shadows,



Here is a shot of the scene with the spot light in.




I then went to the ‘gerneral oparametets’ of the lightin and changed the shadows options so it was using a ‘mental ray shadow map’ from the drop down menu, and rendered,

This image is a lot cleaner and crisp by using the ‘mental ray shadow map’ than the original image.


I then selected the ‘Ray Traced Shadows’ from the shadow drop down menu and rendered the scene to see how this would look, this gives sharp, crisp and define shadows.



I then went on to look at mental ray area lights firstly I deselected the light in place and create a new ‘mr Area Spot’ this will cast an area shadow in the correct place, with a blended shadow,



I then changed the ‘area light parameterrs’ this made a rectangle viewable on the scene and this is where the light for the shadows will come from, I played around with the size and figues accordingly to the space of the objects.



Here is a shot of the rendered image using the ‘mr Area Spot’

As I found out this gives a lot more in-depth shadow and looks a lot more life like as in how the shadow has a border around it.
