How do you apply bumpmapping to this? I believe it explains in the tutorial but i do not get how, I'm using photoshop as my image editor, i need help please!

do you mean apply bumpmapping to player models or walls? because I know how to set it up for walls and floors ect but im gonna learn to do player models soon.

I mean, bumpmapping with the Normal map shader, if you read the normal mapping tutorial, it says somthing about it, like "If you want to add bumps and wrinkles, make a Normal map from a grayscale......". I'm using adobe photoshop, if anybody could help, please, i would be grateful!

If you get the Normal Mapping shader working correctly then you're basically there. Normal Mapping is really just an impressive version of bump-mapping.

Typically, you use Normal Mapping to convincingly portray large bumps, like rivets and such. In those cases, your Normal Map will have some fairly high contrast around the rivet. To add small details like cracks or creases, you simply need to add or use some lower-contrast or finer-detail aspects to the image. For instance, if you convert a normal bump-map of cracks and grooves to a Normal Map, it will show small bumps and cracks. Also, when you generate a Normal Map from a high-res model, you can also usually blend the resulting Normal Map with a second bump-map to add fine details--at least that's true of ATI's utility.

Anyway, so if you just want to know how to convert a bump-map to a Normal map in Photoshop, there's a plug-in for it. I believe it's on the NVidia site, but it could have been ATI that I got it from. Check out the "Killer Normal Mapping Link" listed in the very first post of this thread for the specifics.

Hi Drew,

First of thanks for the cool demo and tutorial.

I got the ATI normal map maker and put it on my weapon and it shows up.

I have also attached the action light_perpixel to some light sources in the level
but the shading on the weapon does ot change when below these ligh entities.

I'm sure I'm doing something wrong here..though not sure what it is.

Secondly I have put ur Example MDL crate (32 bit) one in the level and attached
the per_pixel action ,,but it just becomes orange in the level.

Any help on how to get around andget the cool DOOM3 feel to my game

MAybe try lowering all your lighting to black, including ambient and sun. Place an object, assign perpixel lighting action, place an omni light right in the same location, turn it to white. Build and run your level, making sure your player is using the perpixel shader... thats how I always start my perpixel levels, since this technique is wonky... If you see lighting show up att all, go from there.. sorry I cant be more helpful, I actually havent touched this for weeks, been playing with the doom3 engine

Anyone attempt to adapt this to level geometry now that the new public beta is out? Just curious.

Still no chance. Bumpmapping isn't supported for level geometry.

Hi Alexander,

Can u explain what you mean by 'not supported' in specific terms ?

Is there a work around ?

What amount of work is required to get Bump mapping supported for Level Geometry ??

My apologies in advance if you don't know

For getting DOT3 bumpmapping to work, you need the vertex's tangent, which is not avaiable for level geometry. There is no work around, dispite storing the normals in the normalmap in worldspace, which doesn't make much sens.. or generating the texturespace matrix manually, which also doesn't make much sens.

I have a shader here, that will work for level geometry, once it is supported.
