Global Illumination alternatives

[polyneutron]

As for AO and Indirect Shadows. These terms are used pretty interchangeable, that is why there is clear distinction between various xxxxAO techniques (which are usually screen space approximated), and just AO (which is not approximated but calculated from all geometry).

Right, that’s point I’ve totally missed! I really forgot about various AO techniques assuming AO as ‘geometry-only’ thing.

And from slides it you can read that rendering indirect shadows takes only 3ms. For me it is perfectly acceptable.

Indeed, now the point is that would be great if Epic find it applicable, too. (*Because, you know, large user community, various PC hardware, including middle-budget PCs, etc.)
