I think it would be worth trying to spread the images out on the texture so
that you avoid bleed. I'm pretty sure

They look like stork nests to me. ;-) Now all is that is needed are some
storks and their chicks.
I suppose you will want regional variations to match the stork populations?
Ever noticed the bloody great gulls we have winging around the scenery?

However, one reason I didn't spend more time on it was that it didn't
seem particularly useful from a sim perspective. If found that to see
the effect at reason (30kt) winds you either need to be sitting on
the ground or at quite low altitude when your attention is elsewhere.

Hi Stuart,
this tree movement code is wonderful - how could you possibly not implement
this?
I've been looking out of the window, timing the movement of trees in our
forest, and I think the time constant should rather be 1.7-2.0 and the
amplitude about 2.5 times as large - all of which

Glad you like it.
It got stuck under a bunch of other stuff and forgotten about more
than anything else.

It might be opportune to rationalise our tree texture structures to take
that into account.

Vivian,
Your description makes sense in conjunction with a mipmapping issue.
Think about how mipmapping works. The default mipmap generation algorithm
creates the 1/2 size image by averaging each 2x2 block of pixels in the
higher level down to 1 pixel in the next level. Then repeat, generating
