GLSL Lighting Setup

Support Lighting and Rendering

Hello, I recently got into RealTime GLSL Rendering.
I’m trying to achieve some nice shadows, but I can’t figure out how to get a result similar to this one

I got the statue from Blendswap as “testing” subject. The only texture I applied is a matcap image I’m using for reflection only (Blendmode is ADD)

For the lighting I’m using 1 Sun Lamp with this settings

And a Hemi light with dark-blue colour to simulate the ambient light. Altough I’m still not impressed with the result, especially the shadow. I have to put the sun lamp very close to the subject, or else the shadow will stop appearing like in this one:

Anybody got any tips on how I could improve the quality of the scene?

Change the Variance buffer type back to Simple. Increase shadow map size, up from 512, to a higher number for more shadow detail. Also lighten the shadow color itself so it is not pure black.
