We'll post larger ones in the following days.
Actual ones are enough to display the technical differences I think

Thanx for the clarification on caustics Tom!

There may be some minor issues you've noticed and know that this is still pre-release.

Are the issues with the sun casting dark shadows through glass resolved?

I heard adehus and I decide to answer with renders, not the words.

Sounds promising...

rather thana screen shot, I would like to know i it is going to be complx to manage of not... what about a small indication about the learning curve... will there be one..?

to illustrate what I mean about total internal reflections see following image:

two glasses with exactly same settings, except that the left material has NO total internal reflections. (actually without any backface reflections at all, but its one or the other)

Well, the left glass clearly has some internal refraction (BTW: It's internal *refraction*, not internal *reflection*.).

Note the bright reflexes at the glass bottom, which are clearly due to this.

An unevitable problem with internal refraction is that the rays are trapped quite a couple of times inside the body, so often the ray depth isn't deep enough. Therefore you often get dark reflexes in such bodies like here in this image.
To discuss these kind of issues I would recommend to compare Mawell renders with some other standard render engines like Cinema or Maya, which are quite good when it comes to dielectrics.

no, it's internal reflection internal refraction is a non-sense

I agree its internal reflection (Cinema's Banji shader has this option), not refraction but whatever its called the overall improvements shown so far look promising.

@Kabe: total internal reflection is a case were light can't get out of the material anymore, this is what happens inside optic fibers to transport light.

Here is good explaination:

Man, if you don't find a post like this right away you end up on page 9. Jeez. The improvements look great. My request, I want to know how to texture the cups like they did. I have cups in real life that are like that but I don't know how to recreate it.
