Oc­clu­sion

3D World - - TUTORIALS -

Con­tact points be­tween the build­ings and the land were very im­por­tant for in­te­gra­tion. Break­ing this up by tak­ing out ar­eas us­ing a layer mask al­ways helps, but us­ing the oc­clu­sion pass ei­ther in Mul­ti­ply blend­ing mode (which I find some­times dis­torts val­ues), or mak­ing a se­lec­tion of it with chan­nels and then us­ing that with an ad­just­ment layer, has of­ten been the best way to have an el­e­ment sit prop­erly in a scene. I will also quickly paint in oc­clu­sion in cer­tain ar­eas man­u­ally us­ing a soft brush and eye-drop­ping the dark­est value around that area.
