"Spheral gun shader"

Hi gang,
I spotted on one of the thread screen of "Spheral gun shader".

http://forum.unity3d.com/threads/generating-a-collision-mesh-at-runtime.235303/

I'm looking for that kind of shader so badly and that's the only page I found exactly what I need.
I would be very thankful if someone could point me from where I can get / buy or how I should approach to write it on my own (my knowledge about writing own shaders is very basic unfortunately).

Thanks in advance!

Greg

 

Anyone ? is this even possible to build shader like that ?

 

Hi im also Greg! why dont you just contact the person who posted the thread

 

Hi Greg!

This is the first thing I did but he is not responding... : /

This thread is my second shot

 

Try looking into stencil buffer/shaders. I think there are examples around for something similar.

 

Ehh... of unfortunately as I see stencil buffer are not available for unity free.
Anyway, many thanks for help

 

I believe they added it in 4.6 for free as well.

 

Wow, you are right, that's awesome! Thanks mate, I will try it out after upgrade

 

Hi, I was playing with 4.6 and example from Unity Doc - http://docs.unity3d.com/Manual/SL-Stencil.html

With examples at the bottom of this page (Hole & HolePrepare) I was able to achieve "hole" effect but I spent whole day trying to show what's behind the hole (to do "window" hole like on my first link)

Do you know any tip which may be helpful to achieve that ?

That screen illustrate how it looks now:

Any ideas ? I still stuck with it
