No real-time shadows after porting to Unity 3

Questions & Answers

Hello there!

We've encountered a strange problem after porting our project from Unity 2.6 Pro to 3 Pro: We can't seem to get the real-time shadows working again with practically all of the standard shaders.

The only shaders that do cast shadows are vertex lit and nature.

It (unfortunately) only concerns our main project and all scenes in it. A test scene with just a cube, a plane and a light does work in any other of our Unity 3 projects but this.

We have already tried the following solutions, without success

  • Checked all the light settings
  • Checked the camera settings
  • Checked the player settings (forward and deferred lighting)
  • Checked the quality settings
  • Changed the shaders
  • Tried importing working scenes and assets into the project
  • Tried it on different hardware

Any ideas? Because we are running out of them now ;-)

Is it possible that opening in Unity 3 did somehow damage the standard shaders? Or does it sound more like a project settings problem to you?

Thank you!

You'll need to set the project to use deferred rendering if you want point lights and spotlights to contribute shadows. In 3.0, forward rendering (the rendering technique used) only allows directional lights to cast shadows - and 3.0 is set to use forward rendering by default
