hello people......... ludvik. why havent you prepared and released an in-depth tutorial for corona yet? something like the Esherick house you did with mental ray and a couple of scenes to go with it would be great to see. Also an advanced material tutorial of the basic ones like :glass,concrete,cloth,leaf,wood,metals,water,plastic,leather and rubber would be appreciated even if you cant integrate into 3ds max yet eg. archshaders.....dont say its too early and its only still in alpha stages so we dont need to do these yet. if corona has to excel over other renderers when its released commercially it would be to win at its alpha stages convincingly. im not new into archviz but even though corona seems easy its still difficult to achieve great results like some of the gallery works and its due to lack of great tutorials and resources(material converter is great but not perfect)......i repeat, its not too early to do these things!!! peace
