Poser - OFFICIAL F.A.Q (Last Updated: 2024 Dec 14 2:19 am)
If you're using Poser 4 without the Pro Pack, then use the "render" dropdown menu; select Materials, You'll see where it says "Bump Map". Click "Load" and load the file you want to turn into a bump map. A dialogue box will appear asking if you want to convert the file into a Bump Map. Select "Yes".

What I do to create a bump map is make a copy of your original texture, then make it a greyscale image, and mess with the contrast, and save as texture_??bump.jpg then load it in poser as martin stated above.

He he, where would mankind be without experimentation ;-) A bump map is a way of simulating an uneven surface on a figure or prop by applying a picture. The picture holds the information about the surface structure in a grey scale image. Darker areas are rendered as depressions, whiter areas as raised parts of the surface. The bump maps are loaded in the Materials dialog box in Poser, the same where you load the texture. You can make a bump map using the same template as the texture map. Usually i tworks pretty well by just making a grey scale image of the texture in a paint program and inverting it. Poser Pro Pack can use the grey scale picture as is. Poser without Pro Pack needs a .bum file as the bump map. That is no problem, if you load e.g. a jpg picture as a bump map, Poser will convert it to a .bum for you. The only disadvantage with that is that a .bum file is usually VERY large. It's important to note that a bump map does not alter the geometry of the figure in any way, it only creates the illusion of surface roughness when the picture is rendered. Hopes that made it at least somewhat clearer :-)
Well, using skin texture as an example, if the person looks like they are a field laborerer who's 100 years old, with the bump set high, it's probably too high. You want the skin to look real not like scar tissue. A bump map can make a lot difference in a man's texture especially, and used delicately, in a woman's as well. And, of course, it's crucial in Dragon texture. As for experimenting with, like, wall texture-- it's pretty simple. If inverting the bump map makes the grout look higher than the brick then don't invert it. I get mixed up on which is high and which is low-- I think white is high on a bump.

Please be kind to me as I am still new to all this, but how do I create a bump map?? Any and all help is greatly appreciated :)
