Title: I need help with a few effects.
Post by: dexter on October 17, 2012, 09:34:35 PM
Hello all,
I'm new here, and I'm a new WME user.
I'd like to know how to get the following effects, therefore I have two questions in this matter:
1.) I wonder, how to get effects such as sepia or black and white picture. I know that I could to make a background first, and then get mentioned effects by using Gimp or Photoshop, but that's not my purpose. I'd like to give the player the possibility of choice between filters.Therefore, I'd like to ask if there are some full screen shaders or something like that.
2.) My second question is: I'd like to get a half transparent person (actor). My purpose is to get a ghost actor, but I don't know how. I tried to use a half transparent texture, but the final effect wasn't too good. The triangles are too visible. Is there some other way to get this?

Thanks in advance for any helpful reply.
cheers!

Hi

WME doesn't have full screen shaders so you can't do what you are asking natively. It's possible to create a plugin that does that (it's been done for another commercial adventure).

As for 2 I can't help you because I don't use 3D characters.

Thanks for reply. However I still need some help, how to make a ghost:) I made a 3D actor, but I would like to get the semi-transparency effect.

For the 3D ghost, use png images as the character textures, and in photoshop change the opacity of the pngs to say like 50%

Well, I did it that way, but the final effect isn't too good. In the game, my model looks like in the picture below.

For a head it doesn't looks bad. For a trousers try to remove all intersecting polygons. If I were you I'd start to think about 2d character. It can be done with 3d character but you will need good shader but from I know wintermute doesn't have any shaders.

Of course wme supports shaders for 3D characters (http://docs.dead-code.org/wme/inside_effects.html).

That's good odnorf :)

My game will be fully 2d point'n click adventure therefore I said from I know.
