Is projection painting available in Blender 2.5?

(1/4) > >>

Wolfsong:
I've looked through the 2.5 interface and have searched all over google, YT, etc to find this info for myself, but no dice. Check out this video, specifically the actual 3D texture painting part later in the video (the earlier GIMP portion isn't relevant).

Basically, I think the way this person is painting their terrain could be very useful in texturing my 3D tiles... However (of course) the tutorial refers to the 2.4x series of Blender, and not 2.5. Any searches I've done only bring up 2.4x tutorials for texture painting.

So I figure I'd ask here to see if maybe someone here could help out with finding it. If not, I think I'll just go back to 2.49. Frankly, 2.5 and the changes they're making between versions is proving to be more annoying than anything else, IMO.

[EDIT] changed the topic heading for clarity. Cheers. >kat<

I'm not sure what exactly you're referring to, but texture painting in 2.5 is certainly possible. In fact, it seems to me that it's much more powerful than the version available in 2.4x

First, make sure you UV Unwrap the mesh for the texture to have a way to be applied to your model.

Then, in the drop down menu that has "Object Mode" and "Edit Mode" there's a few other options. One of them is "Texture Paint". Click it.

On the left hand side of the workspace, if you have default configuration settings for Blender 2.5x, you'll be presented with a color wheel and a series of different menu options. One of these is Texture. Open it up and you'll see a checkerboard pattern because there's no texture applied to your paintbrush yet.

You'll have to make a new texture as you normally would if you wanted to apply it to a mesh, then select it as your texture in the Texture Paint's Texture menu.

One of the things to pay attention to is the Project Paint checkbox in Texture Paint's settings menu. With this checked, the texture you have selected is going to be applied perpendicular from the camera's facing position. I haven't figured out how to properly use it to prevent texture stretching on surfaces curving away from the camera yet.

Another interesting feature is the Quick Edit button in Texture Paint's settings menu that will open up the image editor of your choice if you've set one in your User Preferences and lets you draw directly on the mesh from your camera's last point of view. When you're done, you can save, exit the program which brings you back to Blender, then click Apply to see your model automatically update with the new texture info. Pretty neat tool.

Wolfsong:
I guess I should have been more specific.... :-p My bad.

I'm referring to how he uses that "clone" tool to copy directly from a texture map..

Been trying to find that tool in documentation and in the program, etc... Is it still possible to use that specific technique?

I like that particular approach because it would allow me to maintain the same UV coordinates from one model to the next, so they would (theoretically) line up properly and you wouldn't see any seam-lines where the texture ends on one tile and continues on the next.

I like how it gets the same results as using GLSL blending, but that you're painting the actual physical texture and not using a technique that's specific to Blender. In fact, I think he says in the video that they added that capability specifically for people who don't have GLSL support and can't use that method.

Yes there is, and yes, the current docs are woefully out of date. The only vid I've found which mentions the clone paint feature is Messers Williamson and his making a concrete barrier. It's a vimeo vid so you have to pretty much let the entire video load before you can watch the bit you want, which is about 22 minutes in (the entire vid is about 1hr).

Quick rundown, select your textured object and go into "Texture Paint" mode (make sure you can see your textures - "Alt+Z" to switch to "Textured" view). In the "Brush" section (ToolShelf should be open - "T"), click the thumbnail to view the brush options. Click "F Clone". To paint, hold "Ctrl" and LMB click anywhere in the texture to select a 'clone' area, then just paint - that last one is important because you can't choose or set a clone selection using normal mouse clicks so nothing will happen.

Wolfsong:
Ahhh nice. Thank you very much for that.

lol the ubiquitous barrier video. I was searching through Blender Cookie for some tutorials between yesterday and today and found it funny that that tutorial is categorized under almost every category in their tutorials list it seems. Though, I guess since texturing is a fundamental part of any project, it makes sense.

Of course, I didn't think to check it out. Natch.

Let's see how this goes. I really hope this works out as I'm thinking it will. That'll be a major milestone crossed for me, as how to handle the texturing across 3D tiles in a way that's not specific to Blender is the one thing I was still trying to find a good solution for.
