I will disregard the tactile surface properties (bumps) as I am not going to make any close-up shots for curtains.The main form is made up of folds which is related with how the curtain is sewn and hang (again this is the coverage of the modeling stage).On silky curtains, there are reflections.Another reason for this is the folds (which is very important for the modeling stage which is not in the scope of this mini-tutorial). This is like the Fresnel reflection property. Curtain seems to be more transparent in the viewing direction and gets less transparent on sides.You may want to have a much different curtain with lace or with embroidery or with green leafs etc). (Of course this is the curtain I want to create. When I look at it I see white color with some stripes.I tried to see with child eyes what I see when I look at them and what it feels like when touched. I looked at all the curtains around me, and see how light passes through, and how lights spreads on them, how curtains behave towards light and different light conditions. Surface Properties ( Diffuse Color, Texture, Bumps, Holes, etc.We can categorize these features this way… For complex textures, I sometimes write down these features.
I think this is the most important step for creating realistic materials and textures. Initial Steps Prior to Material Creationįirst step we need to make is to define the characteristic features of our material.
Hello, Many people were asking me to prepare a tutorial about how to create a curtain shader and here is the mini-tutorial I promised for Ronen Bekerman Forum which has been one of the leading and creative arch-vis sites that I feel happy to take part.
