Sounds like something for the Open MW team to take a bite in!

I'm not sure I like this bumping of old 'interesting discussions'...

Hey guys, if anyone know how to use overlay, he should know - that same effect we can make in Photoshop, simply add new chanel with "detail map", and overlay it on base chanel, and would be same effect, but u shouldnt add dm on mesh + u shouldnt take free 600kb space on computer for dm texture.
? Tested by me.

(:

Any disscution?

It would not be the same effect in that the addition of an actual detail map texture
interacts with world/ingame lighting (where the lightest and darkest parts of the D-Map
are effected less by lighting than the parts that lean toward a grey/medium tone). In other words,
this allows for a slight shine on the part of the light areas of a detail map and true shadow
in the darkest parts. An overlay of the D-Map on a base texture in an image editor would
not have the same effect .

Well the idea of detail maps is to use a rather large detail map (say 2048x2048 on modern systems) and overlay that on top of the lower resolution base textures to provide more 'detail'. Although the 2048x2048 detail texture is large, it can be placed on multiple different base textures and so is only needed once in video memory. So while you're correct that you can get the same effect in photoshop if the detail texture is the same size as the base texture, this is not the way the feature is intended to be used IMO.

Hmm... Intresting way. Thanks for answer.

Even don't know... Ive tested it, and looked on Detail map, and on overlayed map, and saw same effect... Scratch...

An actual detail map applied is not the same as making an overlay in Photoshop/GIMP/PP/etc on a base texture alone ...

(*and this has many filters and overlays applied to it as it is)

This is the evidence I have and I hope that it speaks for itself (I promise
I was not making up what I said for the heck of it, but from tried and true first
hand experimentation and implementation) :shrug:

Take Care :angel:

Thank you Westly. Big thank you.

Umm... The download is broken now. And Google search turns up nothing. Would someone be able to share a working download with me, please?
