i have searched google for hours on baking the normal map for a high poly mesh to use on a low poly mesh and found stuff on xnormal, melody, denormgen and also in blender itself, but i could never get it fuly working. Does anyone know of a step by setp tutorial on how to get a normal map of a high poly mesh to use on a low poly mesh in any good program, but it might be better if you could find a good tutorial for blender itself.

You obviously didn't search very well, because I googled and pretty much instantly found this:

http://feeblemind.tuxfamily.org/dotclear/index.php/2005/08/23/43-tutorial-blender-and-normal-maps

It should be what you need.

Four steps:

1. Create an UV map for the mesh;
2. With the mesh selected and in "UV Face Select" mode, create a new image in the UV/Image editor panel (Image->New) - if necessary, use the "split area" feature to create a panel, and change its type to UV/Image Editor;
3. Once you have created an UV map for the mesh, still with it selected, press control+alt+B or go to Render->Bake Render Meshes->Normals;
4. When the baking process ends, go to the UV/Image Editor panel->Image->Save As. Save the result under any name.

Done.

To avoid further questions regarding baking, please, try the other options is the Bake menu. You may bake any type of texture to an UV map, Normals to UV map, Ambient occlusion to UV map, the complete result to UV map, textures from one UV map to another (impressive example).

Have fun..

ya guys i found all the things u showed me, but that was not the answer to the question. Im sry if i didnt explain well and i did search for hours. the thing is the stuff i hav found was great, but when i tried to do it for real something would always go wrong. What i asked for was a tutorial for any program where they dont just say what to do, but more of show pictures and videos, becuase i am not very good at blender, im more intermediate.

It looks like 5Louiz showed me exactly what i asked for. thanks everyone especially 5Louiz. I have to check out those videos.

I see, I don't know Blender myself, so I wouldn't be able to make one for you and I don't actually know of any laying around that go into that detail.

Yes.. that is sad.

This page states that TSNMap will be implemented. As far as I know, 2.45 will be a more stable branch with bug fixes and no new feature.

Tangend Space was planned not very long ago, but some projects are requesting this feature. I guess that we can hope it comes out soon. If not in 2.50 - which follows 2.45, in 2.51 or 2.52
