I've been looking around the forums. What I gather is that dot3 bumpmappiong of level geometry will be available in the next public beta. I'm trying to schedule some work that needs to be done. Am I correct in assuming the next public beta will have dot3 bumpmapping of level geometry? Also, does anyone know when the next beta will be released?

Any help is appreciated.

Yes, the dot3 shader itself will work on level textures, but not in texture-space, so it's quite useless.

Last time jcl mentioned anything he said in approximately 3 weeks(if there are no outstanding bugs). That would put it at somewhere around July 1st.

What do you mean by this? Thanks.

The bumpmapping calculation needs to be done in texture-space for some reasons. If not, you would need to make the normal map in world-space (or any other), you coundn't animate your models, ect. For level textures this means that you would need a different normalmap, for every wall that faces an other direction.

For building the matrix which transforms your coordinates to texture-space you need the vertex' tangent, which isn't avaiable on level geometry, at the moment.

When do you think this will be added, I would like to see DOT3/normal maps for the level geometry too.

Maybe I'm stupid, but how exactly would normal maps be done on level geometry? I know you make two seperate models for normals maps for models, but for level geometry...?

yes - this is a way of generating normal maps. But say, you wanted to have a bumpy wall. You could import a totally flat box/plane object - and then the one of the wall - and generate a normal map for that wall.

Then this normal map can be applied to any flat surface to get the same effect, thus, if implimented, it could be applied to level geometry.

EDIT: So you'd import both on top of each other and use a script? I think I get it.

I always just thought via c-script you have two textures on a wall at once, the normal texture, and the bump mapped texture, and when the two combine you get the final result of an uneven surface of bricks, or whatever it is you're doing.

Is this not right?
