Meteors going up & down at the same time
« on: August 25, 2014, 03:05:20 PM »
My Megatree this year is a 180 degree 48 strand X 150 Pixels 5VDC 2811's. Big improvement from last year. (36 X 75)

What I want to do is have meteors shooting up & down at the same time on the megatree. My Initial inclination is to have my 'odd' strands of pixels on one model and my 'even' strands of pixels on another model. This way I believe I can have one model shooting meteors down from the top of my megatree and the other model I can have meteors shooting up from the bottom at the same time.  It should look cool??

When configuring models, I don't believe there was a way to have a starting 'channel' actually having a higher channel number than the ending channel number on every strand. On every one of my strands and stars, each 'strand' has a starting channel number that has always been lower than the ending channel number.

My first question, is it possible to have a starting channel number on a strand to be higher than the ending channel number?  And the more important question, is it really necessary?  I believe on one model I can have meteors going up and the other model I should have meteors going down.  I don't believe it will be necessary for me to  to re-configure starting and ending channel numbers for half of my strands.

This should be easy to do.

I am going to try this tonight. Am I forgetting something? --Greg--

i made a video to show how to get meteors going up and down
https://vimeo.com/104350534

you cannot have ending channel be less than starting channel. i dont understand when you would ever need this?

thanks

Sean,

Sorry, I missed the video. I usually watch all of them usually a few days late late but I eventually watch 95% of them. I'll watch this video tonight. Thank you.

But to ask as to why you would want to have a starting channel number to be lower than the ending channel number, suppose you have a single strand and want to have both ends of that strand come toward each other and meet in the middle. This works great for the star model as the star model is basically 5 different 'single strands'.

The only way I know how to do this is to divide that strand in half and make two models out of it. Unless there is a 'reverse' command on the effect, I don't know how to make both ends of a 'strand' come toward each other. (If anybody else knows an easier way let me know please)

 Having a model with a starting channel higher than the ending channel would allow much more versatility in programming. Thus the single strand could have both ends coming toward each other without the need for a reverse option in the effect.  Since many of the effects now have a reverse or direction option my star (which is basically 5 separate single strands) can appear to have both ends coming toward each other and meeting in the middle. This effect looks so cool as it looks like an 'explosion' of light when both ends meet. It's an easy work around with the direction option.

Circle effect, fireworks, do not have a direction option so I cannot experiment to see how it might work with a star model making the effect culminate in the middle of the star. 

Thanks for all your work!! --Greg-- down the street in Highlands Ranch!!--
