I once saw a tutorial somewhere on this sight I believe that explained how to properly rotate a texture and align it... although this was done with a small trim I know the same concept can be applied to a larger brush texture. Does anyone know where that tutorial is or explain how to calculate the exact "rotation" and "shift" I need to have a nearly perfectly aligned texture on an angle (e.g. a wall going down a ramped hallway).

What I usually do is just keep changing the angles, narrowing it down to the value you need. Dont know of any tut, though. sorry.

I normally find it quicker to do trial and error than bother whipping out a calculator - take an educated guess and then muck around with it until it lines up. Then once it seems to be the right angle, just use the preset alignment tools ("bottom" or "top" or whatever).

However, if you want accuracy, use the inverse tan of the vertical increase divided by the horizontal increase. So for example, if you had a slope going up 64 units, and it was a length of 128 units, then your calculation would be....

tan^-1 ( 64/128 ) = 26.565 degrees

You will need a scientific calculator to do this, although windows has one built in so you could just use that. Oh and make sure its set on degrees rather than radians.

Obviously as hammer only uses the whole number (I think? Maybe it works with decimals, its been a while since I've needed that much accuracy) it will round this off. You may want to round it yourself though, as in this case it is nearer to 27 degrees, but I've a feeling hammer just cuts off unsupported digits, therefore leaving you with the less accurate 26 degrees.

Three words: trial and error [addsig]

reno's nailed it, and i have seen a tut on this somewhere...actually, i have a printout of it....

Think it was Gollum who made the tut. He might have it lying around on his computer.

As do I, with Lep's funny drawings I think it was.

Matts trial and error method works great also, its what I use. I have tried both, and IMO trial and error is alot faster.

Wow.. that calculation method really helps... thanks reno.. although half-life cannot compensate to the thousands place it looks almost perfect going to the hundredths.

The problem is, it still doesn't tile exactly correct, it just goes in the right direction.

There's a nifty method for QuArKers that Rhoads had written a tut on, but being able to wrap textures is not a VHE feature as far as I know.
