3/5/2024 0 Comments How to make a bump mapWhen you need a simple bump map such as leather for chair, it’s enough to play with a few parameters in basic tools in Photoshop. You need to note that not all color textures which will be converted to gray scale(black and white) will give the effect that you want. Any lighter shades provide protrusions and the darker one gives concavities. First part is about bump map, in the second one you can read about process of creating specular maps ) Regarding of creating a bump map I will give you three ways, so you can pick out the right one for you, enjoy!īump map works that the gray color( R:127, G:127, B127) is an intermediate color, that doesn’t give neither convexity nor concavity. So now I present you a brief tutorial of creating these two types maps. Creation of that kind of map(I think it is foolish to use the first map without the other one) from selected or created texture it’s really very simple. Specular map causes that the light refracts more naturally for example, take a look how light is refracting on the leather chair, you know what I mean? Generally, you can use almost the same texture as in the bump slot. Bump map gives an optical bump effect without changing the shape of the model, for example leather or wood. For the purpose of creating visualization often you’ll need a bump and specular map.
