Question: Are the GI sample points in 2D or 3D space?

[PabloMack]

Are the GI sample points placed in the 3D space with the geometry or do they only correspond to the 2D positions on the projection image? It makes a lot of difference whether you want to recomputed the GI cache after slightly moving a camera animation path.

They are positioned in 3D space. For minor camera changes you might be able to re-use the same GI cache without noticing any problems.

That's good to know. It will save some compute time not to have to regenerate them.
