Creating a bump map effect

Hi

I'm in the process of creating specular, roughness, hardness and bump map textures for a 3D model. I'm following a book, but it doesn't explain the process of texturing, so I'm having to figure things out for myself. I'm unsure how this effect was created though. It looks like the same texture you used to get on wallpaper... The original is black and the opacity was turned down to 10%. How do you do apply this effect?

Thanks

Thanks for replying, Dave. I see. I’m still new to all this, so I’ve most likely made a mistake. I figured it was a bump map or normal map due to that sense of depth the texture gives on the outfit. The author’s example texture I downloaded doesn’t list them as bump maps, just as textures under an ’added/extra detail’ folder.

Either way, I want to replicate and learn how the author made these textures so I can apply them to my model. He made four - diffuse, which I’ve done, a specular, a hardness and a roughness. These textures come under his diffuse texture as extra details. I just want to figure out how he achieved this effect.

Thanks


OK

The disadvantage of applying this to the diffuse texture is that when you apply it to a 3D model, the shadow detail will not match the 3D lighting on the model.

But to simulate that effect :

On an empty layer paint with a "splatter "brush (you can download one free in Kyles Mega pack if you are using Photoshop CC)

Right click the layer in the layer panel and in Blending options add a bevel and Emboss effect

Adjust the blending mode and opacity to get the effect you require (I've used "Lighten")

Looks like the only thing you did not change was the layers opacity. Top image it is 13% and the bottom it is 100%.

No, these are both from the author of the book. I was just showing what the effect looks like before they applied the opacity.

Excellent! Thank you, Dave. As soon as I’be attempted it I’ll upload the results.


Will practise some more with this today, though I was struggling to replicate the effect. I even checked and copied the properties of the author’s textures, but still wasn’t getting the same results to my satisfaction. :-/ They should be light on top and dark at the bottom (like yours Dave), to give the illusion of depth, but I just haven’t been getting that result very well. Plus the spattering effect still looks a bit too pixelated even with the opacity turned down.
