Hi Stuart,
sorry for the silence from my side, I haven't been able to start FG up for the
last week or so, I am a bit swamped in work and family issues at the moment...

I suppose you will want regional variations to match the stork populations?
Ever noticed the bloody great gulls we have winging around the scenery?
Well - I suppose it would be doable ...

I part-solved the screenshot issue. Here's a pic of the "hats" on the middle
distance trees:

You have to be really eagle-eyed to spot them, if you change the viewing

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

Glad you like it.
It got stuck under a bunch of other stuff and forgotten about more
than anything else.
However, one reason I didn't spend more time on it
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 make
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

When I've seen the bits of pixels on the very edges of the transparent tree
areas it has sure looked like a texture wrapping issue to me. This is a
flag you can turn on/off at least at the low level of opengl and I'm sure
OSG would expose this.
Basically the bits at the very top of the tree proba
