I hope this isn’t a silly question, but are there any certain options that must be enabled/disabled for a bump map to work? I’ve tried following several tutorials as far as simple bump mapping, but I don’t achieve the same result. This includes the “zbump” addon. I’ve tried using it but again, no luck. I’m very sorry if this is a stupid question, this is my first time trying to use this technique.

If there is nothing that must be enabled, could someone point me in the direction of a tutorial that they themselves have tried and [I]know [/I]for a fact work? Please?

When you apply the bump map image to the proper texture support, make sure to check the “Enable Bump Mapping” option in the Material:Image window.

Thank you for the response. I really appreciate it. I’ve tried what you said but I still got the same result.... :-(

As you can see, I’ve even tried using “zbump” which is supposedly less complicated. You just plug in an image and it goes, but it doesn’t work either.

Make sure to draw a render region so that you can preview the effect. With the “q” key, draw a rectangle around your sphere and you should see the result. Not all geometry maps are visible in the viewport…

good luck!

2 ways to do this using default nodes:

1. Connect your image to the INPUT port of a Bumpmap node. The Bumpmap out to the BUMP port in your Phong OR the Bump Map port of the Material. Make sure that your geometry has a texture projection.

2. Use a Bumpmap Generator node. Connect it to the BUMP port of the Phong. Open the Bumpmap Generator and re-select your image from there. Again make sure you have a texture projection.

Have a look at these tutorials http://www.kim-aldis.co.uk/drupal-6.1/RenderTreeTutorials

There’s a well explained bump map video.

There are several ways to achieve bump map: normal bump, zbump, bump map generator, etc. Check my rendertree connections below using zbump. You can also plug the zbump node into the material bump map port like you did and then play around with the settings in the PPG (remember to try negative values to invert the effect!). While using zbump like I did, do not check “Enable Bump Mapping” on at the image PPG. Also make sure to check your render region settings ‘cause you probably don’t want the texture projections to be rendered, right? ;)

Are there any options that I may need to change in the render manager? I’m following everyone’s images in the render tree but its always the same result…

Leo, I greatly appreciate you taking time out of your day to help me. As you can see I do need it. However, I still cannot achieve the result you have in your pictures. Is there something in the render manager I should try changing? Is it something with lighting? Is
there a configuration while installing I may have missed? I’m completely lost as to why I cannot get it to work. Here is an image of the result I got while copying your image in the render tree.



As you probably noticed, I still can’t figure out how to get rid of the green line. But in all honesty, it doesn’t bother me half as much as the bump map problem.

The problem is most likely modtools - it lacks mental ray, so using the render region isn’t going to display the model any different than the normal OGL viewport (hence you can still see the texture projection).

You’d have to set up a real-time shader in order to be able to see a bumpmap in modtools.
