Quote - If you have been reading the thread "Nodes for Dummies", you'd have heard me discussing hyper-colors and hypo-colors. A hyper-color is one with an RGB component that is more than 1, which is what you're asking for here.
Now there are many ways to produce hyper-colors in Poser, although you cannot directly SEE any of them. The simplest way is to take an existing color and multiply it with a big number. For example, if you start with RED RGB(255, 0, 0), which is numerically [1, 0, 0] and you multiply by 5, you will get [5, 0, 0], a hyper color. And when you look at that in a slightly reflective surface, such as plastic, with a 2% reflectivity, you will see the red reflection at .02 * 5 = .1.
The easiest way to get a self-lit hyper-colored ball is to put the color or node you want into the Ambient_Color, and set the Ambient_Value to a high number. (Because the output of that channel is the product of color and value - just what you need.) The effective color is Ambient_Color * Ambient_Value.
You did not say whether this ball is to be self-lit or lit by other things. If self-lit, the red ball should have Diffuse_Value = 0 and Specular_Value = 0.
thanks for this. so if i now make a matte in photoshop of a 360 image i can make fake HDRI?
sometime on the internet i find a good 360 image that is not HDRI. so with some knowledge you know where the brightest parts are. so if i could make a matte i could then in the shader writte what is super bright.
correct?
