Blood textures on walls and stuff?

How would you do something like making blood appear on the wall when the blood particles hit the wall?

 

there is a decal framework out there which is free

 

it says its $45.00

 

theres a free version and a paid version

 

Can't find it.

the free version was taken offline long time ago (it was the 1.x version of the same). was for unity 2.x anyway

 

is there any other decal framework free? =/

 

Oh come on :/ someone has to know how to do this...

 

Could try delving into the world of "projectors". When someone gets hit, you create a projector that faces behind that "hit" and casts a blood texture onto that surface.

Tis just an idea.

 

I thought about that, but it shouldn't be that difficult. How do people do it when you put up bullet hole textures? It should just work like that (although I don't know how to do that either)

 

seriously, this can't be that difficult, ive seen this done many times...

 

Just make your own. Get the hit location and normal, instantiate a plane with a material on it. In the shader offset it a bit so there no Z-fighting with the geometry underneath. All of the info on how to do this is in the documentation. Or you could just a projector, but those are quite a bit more costly.

 

yeah look at that new Angry Bots demo. They do that using planes with a material, and it looks just fine and is alot easier than the way the decal system does it.

 

not to my knowledge.


Projectors are not really an option as every object hit gets redrawn once again for the projector
