![]() If you make it too big, it can cause shadows and artifacts to appear. (Poser creates volume effects by essentially filling the empty space in a scene with planes of translucent material, like slices of bread in a sandwich.) If you make this number very small, it will take a long time to render. ![]() “Volume Step Size” controls how far apart planes of atmosphere are positioned from one another when rendered. “Volume Color” changes the color of your atmosphere. The other volume settings shown here allow further refining of your atmosphere. You can also adjust the appearance atmosphere effects for individual lights. Remember, this number controls the maximum opacity of your atmosphere. If you entered “1” here, your atmosphere would be 100% opaque – like a concrete wall! I suggest using a density of around 0.01 for a misty/foggy effect but feel free to experiment. This setting controls the maximum opacity of your atmosphere. Next, locate the “Volume Density” number. Select the “Advanced” tab and locate the “Volume On” checkbox (shown in the picture below.) Put a check here to turn volumetric effects on. (The atmosphere is made of only one material, so there is no need to worry about the “Material” pull-down menu.) Start by entering the material room and selecting “Atmosphere” from the object pull-down menu. To give your sunbeam a hazy effect, you must turn Poser’s volumetric effects on.
