Is there a way to make bumpy rugs? Cause I've never seen a rug with a working bump map. I've tried making a fluffy rug but the bump doesn't seem to be doing anything. Even EA defaults don't use their own bump maps! I've tested that by making a single color texture for one of them. And if you look at EA textures, they have some sort of fake bump overlay in their diffuse images, but the actual bump map doesn't work.

J, I would take your bump map and set one of the channels as an alpha. The normal map uses alpha and the channels to create that illusion.

I'm not sure what you mean, DemonWolf. I've tried all sorts of things, manually and using CrazyBump, the best I could achieve was veeeeeeeeeeery faint bumpy texture that was only visible during ONE day time, completely invisible during the other three.

j, I took a look at your package the other day but was also stumped - I made a new bumpmap for your object by using the nVidia NormalMap Filter, which is the method I use for making bumpmaps. This produced a nice very sharply bumpy map, but when I put it in game I still couldn't see a difference. The only thing that struck me was that your diffuse texture is all smooth, it doesn't incorporate the bumpy effect that your bumpmap has, so it may be canceling out/overriding the bumpy effect from the bump map. Maybe try adding the bumpy pattern to your diffuse texture and see if that improves things. (I love the lamp, BTW!)

Prolly is bumping but its not showing because of the texture, there is not much to bump. (this the bump I made) Its only bumping on the edges which wont show and on the bits of mesh that are extruded, anywhere else there is not much to bump as your texture is flat. If you get a texture of google (here is one I prepared earlier) and make a bump from it just to see the difference Here is your original lamp And here it is with the bump I made using that texture Hard to see because your texture is smooth, but thats what a bump will do. If you are making something to look flat metal or plastic a bump will not do much, they are good when you make wood or material, or in the case of using that texture for a bump, if you texture a metal object with scratchy or paint flaked metal for example, and used the same texture for the bump you will see the difference.

j, could you tell me which item you cloned to make this lamp?

esmeralda I had a feeling that my current bump might be cancelling itself out through the inverted alpha. But, this was the latest stunt in my bump map saga and nothing worked well previously either, lol. I haven't really thought of first applying scratches and bumps to the texture itself and then accentuating it through bump map, silly me. And thank you. @misters Your attempt looks similar to one of my older attempts, where the texture change was super minimal and it only seemed to be visible during one day time. :-/ I just wanted it to look less polished, but this is proving way too much trouble for something that isn't really that important to my object overall, so I'm leaning towards just scrapping the bumpy idea. andrew MisterS beat me, but it was the robot lamp.

If you send it to me I'll take a stab at it. I probably can't contribute anything other than what others have but I'm curious to take a look.
