chrisperry05 Posted February 4, 2011 Share Posted February 4, 2011 Hi, I'm pretty sure this is a simple quiestion but i can't seem to solve it. I want some particles to emit between a certain number of frames. ie between frame 600 and 800. What would be the expression for this, i'm using "$F > 600" but then i don't know how to get them to stop birthing at 800? Is there not an or function or something? ie $F > 600 or < 800 Any help would be really great. Thanks Chris Quote Link to comment Share on other sites More sharing options...

Thanks Chris Hi there, You could try something like this: if($F<600,"emit amount zero",if($F<800,"emit amount eg. 1000",0)) replace text in quotation with emission value, so the first one will be 0 because its before 600 and the second value will be like 1000 or something because its after 600 and before 800. let me know if it works try that Quote Link to comment Share on other sites More sharing options...
JaydenDP Posted February 4, 2011 Share Posted February 4, 2011 oh and take the quotes out too course: eg. if($F<600,0,if($F<800,10000,0)) Quote Link to comment Share on other sites More sharing options...

Macha Posted February 4, 2011 Share Posted February 4, 2011 (edited) just $FF>600 && $FF<800 will do the trick Edited February 4, 2011 by Macha 1 Quote Link to comment Share on other sites More sharing options...
