Mini-tutorial: Wall Bump & Speculars the Painless Way

Maybe I can help a bit. If your wall has just one colour or you are using the exact same texture for any recolours then making the bump is easy. Import all three sizes of your texture into photoshop, convert the images to black and white, either by removing colour or using the convert to Black and white option. If I need a lot of detail I will use the convert option as I can almost control how much white will remain, the lighter the details the stronger the effect. I then use the emboss tool and play around with depth, degree of angle and percentage amount until I'm happy with it. Save as a .dds file and its ready for testing. All the bumps I make for walls are the same size as the texture but the spec I have discovered can be 256x256 no matter what the size of the texture. Making the spec for stone walls usually means I will do the above but instead of the emboss tool I will darken the image or cover the image with black but using 'multiply' with the brush tool until the spec is almost black. If you want shine then various shades of grey produce shine. It's all a matter of practice and personal choice and easy to learn, the results are always worth it when it all goes to plan
