    I was unsure what forum to put this in, so I took a guess.

    If you've ever used Microsoft Paint, Photoshop, or something similar, then you know holding shift lets you draw a straight line when drawing a line.

    I've taken a photo of the street surface, named it asphalt.jpg, put it as 256x256, and imported into unity. I added it to the textures you can paint the terrain with.

    I can indeed paint the asphalt fine, but I cannot seem to draw a perfectly straight line, as none of the brushes I see have a straight edge. I doubt if I could paint it THAT straight if I had a square brush as it seems a bit hard to draw a line only in one direction.

    Is there a command to paint only in a certain direction? Like Shift + Left Click while painting or something? Is there a way to design your own brush shape, square for example?

    Really annoying trying to paint a road or sidewalk on the terrain, any tips for doing this?

    It seems no matter how slow and carefully I move the mouse I just can't paint a straight line more than a few meters, especially if I need to reposition the mouse.

    Use a painting app to create or modify the splatmap and then import the splatmap into Unity. The painting tools in the terrain editor are very primitive.

    :( , so sadly no way to really paint a perfectly straght angle except a square brush and a prayer.

    Maybe they'll add that in 3.0, and the ability to have negative terrain elevation.

    :idea: Would be so nice to hold Shift + left click and just draw a line perfectly. :idea:

    Necro!

    Been searching high and low for a way to simple paint terrain height along a straight line. Unity already features snap settings for game objects - I'd happily pay for a way to 'snap' the cursor along a set axis using Ctrl-LMB....
