I'm currently writing a test using PBR shader.
Right now it works, but I'm using pre-calculated environment (irradiance) map.
I know that an environment is provided with the deferred rendering, but I want to use the texture sampler in the main shader because the calculation for the sampling (importance) is different.
I would like to know if it is possible to access the sampler (to be bound) when during the 1st pass of the deferred. (for example texture15).
Thanks;
