Week 7 , Self Directed Study - Overcast Lighting 3Ds Max

Learning 3DS Max


Week 7          -  Overcast Lighting 


            The 7th week of myself directed study I watched the 7th video of the of the “Let Learn 3ds max” videos on BrandonJLa. Here he talk's and show you how the lighting is different in each scene. He show's you in the control's of what to change and what the settings are so we can use are eye's and match to are own scene's we went out and create. 

          There are different colors of light more blue and some more yellow, This light is important to understand and will effect on how your scene looks. So i took the photo of the ball of and avengers ball and placed it int he scene. One thing I learned was indirect illumination is very important for reflections. Its an easy thing to do and you can turn it on by going to the render setting in the project window by pressing F10 to access them in the V-Ray box. 


         Getting your scene and models to scale is a important thing and a good thing to know when modeling in the industry . People like when you model to scale of the actual object. This is save time for people and glad they showed you how in this video.  In every scene he make a reflective ball and a gray ball. Its a great way to set up your scene for editing , It becomes very easy after a while of learning how to do everything. In this one video you go throw all the steps of what I learned in all the other tutorials only thing different is we have already done it before.  Creating are planes and using camera map to pixels and bitmaps adding you sun and the 3 balls to the scene. Your first render will be very over saturated and this will be because of the V-ray exposure control. This is a key for getting scene lighting right. 

           Its better to change an overcast day to light day but much harder to change a Sunny day to an overcast day. Most of the setting's you change to change the scene are setting's in the VRaySky and Sun . Changing the Sky model to CIE Overcast Rather then Preetham et al.  It changes your sky from a sunny day to overcast and it will give you a goofy result at first but it slowly starts to make your day over cast in the sky and in the lighting. The Size of the Light source will depend on the shadows feather so increasing the light size will help this allot and we will acquire a overcast day once the lights so big. Lowering the Intensity multiplier really low will help darken your scene and give it a better final result.
