Poser - OFFICIAL F.A.Q (Last Updated: 2024 Nov 29 7:57 am)
Simple. Make a greyscale image, and use the template of the object you want to make a bump map for as a guide. Areas that are high should be dark colored or even black, areas that are low should be light colored or even white. If it's in between, it's grey. For example: For a vein popping out on the forehead, take an existing bump map for the figure, and on the forehead lightly airbrush a thin, dark, branching line. Make sure it fades into the rest of the bump map, or it will look like a plateau, not a vein. That's the whole theory. White = cracks, deep, black = bumps, high
Remember, kids! Napalm is Nature's Toothpaste!
Hey there Valandar ... I normally have the opposite. White is light and black is dark. Has always been that way for me in Poser. And ArmoredGideon. Normally the more dreastic the change the more it is noticible. Take a black texture map and just put one bright white line across it and see what it does.
Also sometimes a straight "Inverse" of the greyscale may not put the Light/dark where you actually want it. You can use the Lasso (or wand) to select specific areas and then Invert just 'that' section, or just paint those areas or add highlights. Also mine seem to follow the high=light low=dark path too?
POser tends to be a tad backwards compaerd to the rest of teh 3d graphics world 8 ) for most programmes teh dark/low light/high is the norm.. but Poser prefers teh opposite. basically the higher the lift you want the lighter the shading... Note: the bump wont make any visible differance until the image is rendered... much like transmaps only showing dots until it's rendered.... then you can mess about with the .bum file and contrast to increase/decrease the lift...

HI Can someone please just give me a quick explanation of how I would go about making a bumpmap with photoshop?
