Pushing Su and Twilight to the limit...(my version) advice

[George.Selim]

Thanks Fletch for your comments, frankly I use the attache granite texture but not sure why it didnt show?!
I used refraction (1.1) and shiness (14000) any suggestions

[Fletch]

IOR is dependant on the material. Plastic is IOR 1.1 or something... depends on the plastic.
1.33 for water
1.52 for glass

maybe try IOR of Glass.

This is the final enhancment and I will start a new excercise today I am pretty happy with the result. Thanks to all the comments and directions you gave me every one.

Nice final image, For the floor I used ceramic preset shininess at 85000, and this map.

Thanks Fred for your great support, what is the rifraction ratio
Please let me know if you need any plants with transparent background(alpfa channel) as I found some free on the ne, I can share the link.

hey George,

I had the same problem with the flooring once before.

check this topic:
http://twilightrender.com/phpBB3/viewto ... =11&t=2911

apparently it happens when the back face is painted with the same material as well.If changing that doesn't work, then reverse the face in sketchup and apply the material on the reversed face. Hope it helps.

If you use the ceramic preset, then you will not need to set the IOR, as it is set automatically.
