No, they're made of a blend between diffuse transmitter and phong, which is a nice way to do a Leaf material. (For leaves with no thickness)

:mrgreen: Indeed... my remark was only due to the ior's material, if it was really to be some sort of glass it had to be pure specular

Sprite Test :o (Actually, It's just the glass material with a higher IOR.)

Hey, it's funny I was thinking at leaf shaders yesterday ! Notably, leaves have a different tissues on each side, so I was thinking that a sort of a blend material, but normal based, would rock ! What is called a double-sided material (SketchUp has this by default I think). Could ISL do ?

For instance the top material could be phong+diffuse_transmitter, and downside OrenNayar+diffuse_transmitter. The double material would remain visually consistent if correct blend values are used for each material.

:roll: :P :wink:

I mean what I said Pibuz ! I don't know if we can query normals direction using ISL but that might be enough to make that double sided material a reality...

Shouldn't it be lower IOR? Glass is about 1.5 when water (or Sprite...) is about 1.3.

All valid points, the liquids IOR should be lower than that of glass, bubbles should in my opinion be more to the sides and maybe have clumps of them at the bottom (where the edge is). And straighten that straw! :wink:

The floor on the right side looks strange...

I try to find out what is the special story behind this image... master Ono posting renderings without showing new features... can't be!!!

Maybe some new sun system... the shadow on the let looks quite not so sharp (more realistic) like I remember Indigos sun shadows to be... hmmmm
