Tracker 3881: Cubemap Lighting Beta

[duzenko 659]

The question is, do we need to fix all the A/C light materials to explicitly reference the makeIrradiance function, or to to automatically call it behind the scenes?

 

I would prefer the former as mappers might want to use their own irradiance texture

Since cubelights haven't been used widely yet, it's probably safe just to fix the materials, rather than introduce a change in how they're interpreted.

IMO you have to teach mappers how to use irradiance workflow first, as it isn't widely known.

There are two cures here.

 

1) Change the ARB shader to use standard Irradiance maps then "fix" the makeIrradiace (material keyword)

image generator so that it produces proper Irradiance images

 

2) Have the GLSL shader automatically convert raw cubemap data into something akin to makeIrradiance

in a similar fashion as the ARB shader does.

 

Ultimately, we would want TDM to natively offer something that can easily convert regular cubemaps to proper

Irradiance images so mappers wont need to do all this:
