Thanks Maxxxmodelz  for your comments. It's great to know that Embree is now implemented in VRay too.

That makes 2 world-class products, VRay and Cinema 4D, that have implemented Embree. Which proves that Embree itself is a world-class technology.

Would Embree turn Carrara into a world-class 3D app? Probably not. But it would at least help bring it to the same level as Shade, and that is enough afaiac.

It makes my head smoke when I see Daz developers spend their time, **or actually waste their time, ** on a 1990's technology like fast mipmap as a solution to Carrara's ailing renderer.

I don't think that putting Embree in Carrara's native renderer would have taken much longer than the fast mipmap thingy, but the difference would have been from here to the moon..

At this stage of the game, my recommendations to Daz dev. team are the followings:

1. Take the fast mipmap code out of Carrara and trash it.

2. By the same token take-out the 'summed area table' filtering option and trash it too, because it simply doesn't work. Use it and you will see seams appear in the renders, all over the place. This is another one of Carrara's features that have been shipped without being tested.

3. Fix whatever was done to screw-up the Gaussian filtering option that now runs 10% slower than it did in 8.1.1.12.

4. Implement Embree in Carrara's native renderer, spend a full 2 months testing it on hundreds of animated and still scenes to make sure it's bug-free.

5. Ship C9 and see Carrara's sales go through the roof.

It can't be simpler than that.
