Title: Will sunshafts work with 2dtk?
Post by: Afro-Ninja on September 02, 2013, 04:14:52 am

I don't have unity pro but one of the reasons I would like to get it is for the image effects, especially sunshafts:

http://docs.unity3d.com/Documentation/Components/script-SunShafts.html

will these shafts show correctly through a bitmap image? like if I have a bitmap of trees and the top section is transparent, would the light beams show through correctly?

Hi,

We've just had a play around with this here in the office.  Whilst it worked okay on 3d objects it didn't really work at all on 2d sprites, so I wouldn't recommend shelling out for a pro license just to use sun shafts with 2d toolkit.

ok, gotcha.

do you think it would be possible to create some basic 3d geometry to act as the edges, and then use a shader to turn the geometry invisible?
I'm not sure if it's possible to get the shafts to show through a transparent object correctly.

thanks!

Possibly. It works fine with solid 3D geometry, just not very well at all when not using the depth bffer.

What about with sprites that write to the depth buffer, like clip shader?

Its a lot better when it writes to the depth buffer.
