This would be easier if you had posted an image of what you have so far... A lot depends on the amount of detail and level of antialiasing in your render... I have never worked with vue, so my advice could very well turn out to be totaly useles, but what the hell; you never know... 1) If you only want to blur the background, I suggest you make a seperate render of it, without the vipers. Open this render in ps and apply a motion blur to it (Filter; Blur; Motion Blur...) You could then render the vipers with a complete black background and select them in ps, then copy/paste them on the blurry pic. Selecting the vipers by using the lasso and zoom tool will take a lot of time and effort and may still look crappy after all... 2) There are many ways to create an afterburn and smoke. The best way to do this would be to use a 3d app like lightwave and use particleFX. But I'm asuming you want to use ps for this... One way would be to use a photo of a flame from a candle, apply a subtile gradient in another layer on top of it to ad some color efects and use the erase tool to ad some transparancy at the end of the exhaust. Try the vue forum before giving all this a go, they might be able to provide a much easier solution to your problem. Grtz

Coming soon
