Alright, this is merely a little video to show you how much fun it is to have an ambient occlusion map, generated outside of sculptris (Like in LightWave3d), in Sculptris during painting and bumping. Since it works perfectly well on my old GFXboard at full resolution (1080 HD), it feels like I'm in the middle of a sci-fi fantasy while working on it.
It uses two materials. One is the shadows, so to say. The second material has the lighting material with an ambient occlusion image as texture map (alpha).
This is a little introduction to MaCrea, a material creation application especially designed for use with Sculptris, but equally useful for other apps such as Zbrush or the likes. It creates PNG images of a sphere with your lighting and surface design.
This video is again without sound, since I yet have to figure out how to keep the sync properly, believe it or not. Since I don't think this should delay the presentation of MaCrea any further, I already give you this one.
Download it from my website taron.de under the subject Development or go to the sculptris.com forum.
Here's a little demonstration of what you can do with Reflection images (spherical) within MaCrea. With the brand new "automatic ambient" function MaCrea distributes 13 lights across the sphere based on the loaded reflection image. Additionally there's a reflection diffusion section that allows the creation of blurred reflections up until an image based diffuse illumination. It's really fun to goof around with all that and the results can be pretty amazing. Ceramics, plastics, skin, anything can be easily illuminated by the image of a chrome sphere.
