OK, I agree. Daz is understaffed.

But the fast mipmap thingy didn't just land by itself inside Carrara. Someone must have put it in there, right?

That is what enrages me. To see time spent, actually time wasted, on a 1990's technology that nobody uses anymore, except in low-end game engines.

This is today's technology that Daz beautifully missed: It's called Embree By Intel:

And this the result achieved by this technology:

The time needed to put Embree in Carrara would most likely have been the same as the time wasted on the fast mipmap.

With only one difference: Embree would have turned Carrara into a world-class product worth buying, while the fast mipmap is only good to laugh at.

But maybe it's still not too late. Maybe Daz can make amend.
