Sorry, this aint no tut - I cant muster anything that structured. Maybe therell still be something in here that might help somebody in some way Now, right off the bat Ive got to shout out props to Agent Smith, Blog, Dan Whiteside, Drac, Flak, MarioG, Ocddoug, Rochr, Roobol, and Woodhurst to name but a few - because whether they know it or not theyve been instrumental to the process, and it probably wouldnt have happened if I hadnt had the benefit of their images and information. Go look at their stuff, read their forum posts and replies, find their sites, and pour over their tutorials. If thats all you get out of this then itd be enough but Ill try to add some additional value anyway. 8) I realize this is pretty lightweight - if theres something you want to know that I didnt cover, just ask.

The Sky Well the mega primitives werent working, LightWave particle emitters and hypervoxels were interesting but not that interesting, and I didnt get around to trying to simulate particle effects by clipping the tips off terrains, so yes the sky incorporates picture textures of tornadoes in two separate locations in addition to the Bryce sky. Pic selection and matching is pretty crucial, as is approaching it from the standpoint of integration as opposed to just tossing something up as a backdrop. You can use symmetrical lattices instead of and in conjunction with the 2D planes, but the key is having them be reactive within the scene so that you can tie everything together with lighting and atmosphere instead of simply trying to drop pictures in. For this image I used haze and fog blended with sun at 100% color and luminescence, spherical clouds casting shadows, sun shadows on, soft shadows enabled, and no other lights other than the atmospherics and sun. I also made separate renders with the tornado in two different positions that I blended together in post. In reality you are going to use whatever works for what you are trying to achieve.

You will undoubtedly have noticed the grey boxes - the dooways were booleaned into the original model and the ungrouping and movement made them effectively unrecoverable, so I had to move boards around to make the doorway again too which ends up being a tedious process with all the detailed pieces in a Meski model.

Oops! Sorry about the formatting - looks like anybody with less than a 19 in effective diagonal view will be scrolling back and forth... Sorry...

Thanks man... for the info. 8)

lol, awesome!!! drac

I have my res at 1400 so no problems. All very impressive. You gonna give us another tutorial on the twister itself? It's 3d, or 2d plane?

very cool-- thanks for the insight, it is much appreciated.

Thanks for the info and the time you have taken posting it to us,much appreciated.

Some great insight on a brilliant Bryce composition.

Thanks for this ddruckenmiller. Saved me from having to ask you how you did it ;)

Now it is perfect!

What could we do for it to make it more realistic??? Hmmm.........# Add a wicked witch on a bicycle? A young girl with a small dog?.................. Great piece btw!

Thanx a lot for this "big one" buddy :o)
