Switching shaders at run time.

[YouGroove]

Could it be possible to switch in real time a shader for some character to another shader ? and not affect other same characters copies ?

Can Lua variables be passed to shaders ?

I've been considering adding scripts to materials in the same way entities work. This would not work on a per-entity level with batched rendering, but characters aren't batched, so in that case you could send some different variables to a shader for each instance.

 

You can also just use Asset::Unmanaged to load a unique copy.

You could also use a texture atlas, maybe controlled by ex_color.a or something. (Rick had such a shader in 3,0)

 

But scripted materials sounds very flexible, me like.

Yes could be usefull. My goal would be to swicth shader of character at any time with some script variable in input.

Example :

- shader change to a special shader effect (on gameplay conditions)

- shader LOD : near distance diff/norm/spec/glow , long distance : diffuse only shader ( sounds lot of performance gain here )

 

This would not work on a per-entity level with batched rendering

This could apply : If you make level divided in sectors and portals visibility , you could switch shader to simple diffuse one when sector is not one where the player is around.

Why can't you use Material::SetShader() / GetShader() and all the methods of the shader class?

[shadmar]

It would change all instanced models too.

Not if using Asset::Unmanaged flag, as Admin mentioned.
