* Ctrl-Alt-MMB: Paste Texture to entire Brush: Copies shader from Clipboard to all faces of the targetted brush.


Once you picked your texture with MMB and copied it into the Texture Clipboard, the name of the texture appears in the status bar.
Please follow the links for a short introduction of these copy & paste operations.


=== Copy Texture ===
==Scrolling Textures with the Mouse==
This command is available via the MMB (click into the cam view) or the Menu > Edit > Copy Shader. When using the MMB to select a texture, the shader of the clicked object is loaded into the ShaderClipboard.


=== Paste Texture (Projected) ===
This was thought up by SneaksieDave. You can scroll a texture around to align it using the mouse as follows...
This is useful to texture patch caps or brush faces that are adjacent to each other. See the following example:

* Select translate mode with the W key
 
* Put texture lock ON (yes ON)
The left shot shows two brushes and a patch that has been created with the "cap selection" command. The rightmost brush is considered the "source" brush, so we copy its shader by middle-clicking it. The shader is now in the clipboard.
* All in the camera view....
 
* Select the WHOLE brush. The red/blue translate arrows should show on it
Now hold down the Ctrl modifier and click on the other three objects with the middle mouse button. The texture is pasted onto the target objects so that the transition between the objects is seamless - technically spoken this is a projection. Imagine that you project the texture using a video projector, it's more or less the same mechanism.  
* Click the Select Faces button - it should lock down and the selected brush loses its red highlight and the translate arrows and a green dot appears on surfaces.
 
* Now select the FACE (Shift+Ctrl+LMB), it turns pink and the translate arrows re-appear.
'''Note''': It's important to note that this only works from brushes to patches, as only brush faces can be used to project textures. Patches have no uniform scale and rotation and can't be used to retrieve a plane to project the objects onto.
* Select either translate arrow to get direction
* LMB to drag the texture around. You can drag outside the texture which is handy if it is small or narrow.
* Adjust the ortho grid size for speed.
* You can also, at this point, use Alt plus the arrows to fine tune the position.


== Scrolling Textures with the Keyboard ==
When a texturable object (brush, single face, patch) is selected, use the arrow keys while holding down Shift. This will translate your texture up/down/left/right. The stepsize is determined by the Surface Inspector's settings.

In DarkRadiant there are some quite useful texturing tools available. This document describes these tools and how and when to use them.

Brushes vs. Patches

There are some texturing commands that work differently for brushes and patches, because of the way these primitives store their texture information. So beware that using the same command on a brush doesn't always yield the same result when used on patches, although DarkRadiant tries to do its best.

Natural

Natural for one works differently for patches than for brushes. Basically it tries to apply an undistorted texture with the default scale on the target. This is of course more easily accomplished for brushes (because their textures are always undistorted) than for patches.

Texture Copy & Paste

These are the most powerful texturing tools in DarkRadiant. There are several of them available, all can be accessed via the Middle Mouse Button (MMB):

Please follow the links for a short introduction of these copy & paste operations.

Scrolling Textures with the Mouse

This was thought up by SneaksieDave. You can scroll a texture around to align it using the mouse as follows...

  • Select translate mode with the W key
  • Put texture lock ON (yes ON)
  • All in the camera view....
  • Select the WHOLE brush. The red/blue translate arrows should show on it
  • Click the Select Faces button - it should lock down and the selected brush loses its red highlight and the translate arrows and a green dot appears on surfaces.
  • Now select the FACE (Shift+Ctrl+LMB), it turns pink and the translate arrows re-appear.
  • Select either translate arrow to get direction
  • LMB to drag the texture around. You can drag outside the texture which is handy if it is small or narrow.
  • Adjust the ortho grid size for speed.
  • You can also, at this point, use Alt plus the arrows to fine tune the position.

Scrolling Textures with the Keyboard

When a texturable object (brush, single face, patch) is selected, use the arrow keys while holding down Shift. This will translate your texture up/down/left/right. The stepsize is determined by the Surface Inspector's settings.
