How to sample a texture in a custom deferred lighting calculation?

Hello there guys. This isn't a comeback yet, I'm just helping somebody (not sure if I'm gonna check the dozens of alerts yet). That being said:

I'm making a custom lighting for the deferred path, and I'd like to sample a texture for values, however, I couldn't find a way to access a texture from there. Is there a way to do that?

Thank you in advance.

 

OK, I solved it by passing the texture in Shader.SetGlobalTexture so I just had to declare the sampler2D in the shader (and not the texture in the properties). I don't know if this is the most appropriate solution but it works.
