BLUR HDRI KEYSHOT FOR ZBRUSH UPDATE
When you slide, you will see the "wall" around the window update to a darker grey, while the windows stays pure white. With the options that pops up you can alter the levels of the underlying pixels without making definitive changes.ĭrag the black-value slider to the right until it is at level 42 or 43. Next, introduce a Levels-channel to the background by clicking the channels-button and scrolling to levels. The first thing that we do in Photoshop is making a simple pure white window in the middle of a 50% grey background Set it to 850x850 pixel and 16-bit colors and save it as 4.psd. For the sake of purity I haven't edited the image afterwards: This is the render. The final render before we proceed: This image and the shadow are purely made with the HDRI that we will make ourselves without the use of a camera.
I won't go into minute details of setting up the scene. This radiance document will have a 32-bit range of dynamics, enough information to actually light your scene, throw shadow and make reflections without the use of specular shaders or channels. Then of course, you do it yourself! Apart of course from any major 3D package, you will need Photoshop CS2, in order to be able to merge a number (I will use 7) of "lighting situations" into a single radiance document.
BLUR HDRI KEYSHOT FOR ZBRUSH FREE
But when your client wants a simple classic four-window reflection in his water drop, none of the beautiful things they sell, nor any of what you will find that is free to use, will do. There's a lot of HDRI photo material available from parties such as ' Sachform' and ' Dosch Design' that can be very useful in giving light and atmosphere to your 3D-scenery.
I guess the 32-bit room that we will use is still far from insufficient to capture the whole range between dark and light but it does do an extremely well job. The human eye is so fast in adapting to different light situations, and your monitor is actually so bad at representing the enormous space between the inside of your jeans back pocket at night and a bright day at the equator, that the fact that the sun is so powerful may strike you only after a day on the beach without a proper sun block. Otherwise, simply Google HDRI and find all about the subject. As you may know by now, an HDRI-image is the simulation of light in its natural state: as a high dynamic physics feature. In this new tutorial, I will guide you into making a simple self-made HDRI from scratch, without the use of a photo camera.
