The headline says about everything I think. The shader doesn’t have to be real HDR lightning, my idea would be to modify the specular shader by boosting the contrast to get a glow-like feeling instead of the default specular shine. Is there anything like that out there for Unty Indie?
Not possible with the free unity I fear
PostFX effects / render texture based effects require Unity Pro
This may be an old post, but here, Come to this thread: http://forum.unity3d.com/threads/198568-Epic-Radial-Blur-Effect-for-Unity-Indie/ I have posted a fake image effects package for indie version of unity!
I also read your request for fake HDR rendering, i could give that a shot (I am currently working on a joint project with another forum member to get bloom in this)
