I´ve followed this wiki http://guildofwriters.com/wiki/GLSL_Stencilling and have some trouble;

When I try to paint my stencil in 3D view I just seem to access/paint the first layer (the base, topmost in the texture list). It works fine if I select the stencil in UV/Image view, and paint there. It updates on the fly in the 3D view...but it´s quite annoying that I can´t reach/paint on the stencil there. Quite sure I´m missing some basic stuff here (really new to Blender) but I post here if someone know of any wierd stuff like this accuring.

PS. I have checked the Blender GLSL Materials in the Game-menu as well...

Ah, so you can't paint in the 3D window... hmm. Are you sure that your viewmode is set to textured? To check, press alt-z then try to paint. You can tell if you're in this mode if you can see the icon in the right of this picture:

No...I CAN paint in the 3D view - just not on the right layer. I must be missing something basic here...I just want to be able to paint on the stencil-layer like I can do in the UV/Image view.

ok...this is important ... took me a while to get the gist of it ....

to quote from the Blender website ...

"Getting Started
Once you have un-wrapped your model to a UV Texture, you have to:

Load an image into the UV/Image Editor (Image->Open->select file) , or
Create a new image (Image->New->specify size) and saved it to a file (Image->Save->specify file).
You cannot paint on a mesh in Texture Paint mode without first unwrapping your mesh, and doing one of the above steps. After you have done these two things, you can modify the image using the Texture Paint mode. Once you do:
In the 3D View window, select Texture Paint mode from the mode selector in the window header, and you can paint directly onto the mesh.
In the UV/Image Editor window, enable Texture Painting in the Image menu
In the UV/Image Editor header, click the magic pencil ... "

remember also to select the UV layer for the STENCIL in the mesh tab ....




the full intructions are HERE

oh ... and double check which image you have loaded into the UV window ... you may think you have the correct stencil loaded into it ... but check the available images anyways ...

I thought maybe creating a new UV layer in the editing buttons F9, would have been what you're after.

But Bob is correct

Yes, bob has it. It doesn't matter what layer you have selected in the Materials panel when you want to paint on a certain texture. What controls this is which UV Texture you have selected in the Mesh panel.

Ok...I´m new to Blender, so I´m quite confused. Especially regarding the materials and selection of these.
Anyway, I was able to get this to work;

I don´t get the thing about having multiple UV Textures (I assume this is what I as a 3DS Max user refers to as UV coords?) since I want all three textures to use the same coords (at least in this test).
The way I was able to select and switch between the layers affected was this:

- Select model in Texture Paint mode
- Press Tab to enter Edit Mode
- In UV/Image Editor, select the texture I want to edit
- Press Tab to exit Edit Mode and return to Texture Paint mode

Thanx everyone for helping me out with this.

What everyone is referring to as 'UV textures' can be found here:


They are each different sets of UV co-ords

EDIT: that picture was hopelessly small. a larger, more useful one is attached
EDIT2: two more images have been attached. these show the locations of the things Grogyan is explaining.

Confusing I know

Its all pretty well covered here
Using_stencils

Edit, never mind, Ardent Red has shown you how to paint on the correct layer, the buttons to the left show which texture show in 3D view
The layers you paint on are vertex colours, they are below the UV texture coordinate layers
