Load random photos from folder as particle

[vjsaw]

Hello,
I want to load photos from one ore different folder as particle .

How to set a folder as source of particle?

How to keep the ratio from the fotos?

What I did for now. Is creat three particle systems, and change the fotos as particle manually, and set each particle system to the ratio I need (16.9 / 9:16 / 1:1 / 5:4) that works fine. But I would be great to automatize it and have "birth to death" transitons between the random picked photos.

If you want to have a look inside. here is a link https://we.tl/t-LTWrxZRqpm

thanks a lot

Hi
You can not load a folder as a particle
You can create a sprite sheet. See the "Examples/Tutorials/Explosion with spritesheet.compo"

To keep the ratio you need to set the scale of your particule

Or precompose your picture into a 1:1 compo

With the Age selector you can put multiple picture in the renderer it will make a "birth to death" transitons

you can watch this Video https://www.youtube.com/watch?v=IIs1LwrT79E&list=PLwlsjXYLydHka0bIl_1HkV86XF0UnCYRA&index=23

Hello,
thanks a lot! Thats helps a lot! I did it this way. Works with sprites ans defaults. It keeps the ratio and do a nice random between the particle pictures.

Would be great to a a little script running loading it by itself from a specific folder. But yeah, fair enough : ): )

The quality of the small particle pictures doesnt look good. Lots of aliasing and noise. I (maybe) understand the aliasing , but where is the noise coming from? Its getting better as bigger I scale each compo. (see above) Is they any way to "clean it up"?

I allready tried to increase the Quality setting from the compo from "automatic" to "Multi Sampling 64" as well the GPU Setting "Multi Sampling 64" that doesnt help. ANy idea on that?

Thanks again

Here the Output

[RBasile]

Loading a image freeze the output it's not recomended during a show.

You may need to change the interpolaton to nearest in the renderer setting so it's not blending betewn image

and in the adcended mode you can chose the map resolution

In the master comp you do not need to go higher that 8 on the multiSampling it doesn't make a beg diferance

Thanks! I havent recognized it yet. But thats ok for now. I dont need to be onscreen whole time.

and in the adcended mode you can chose the map resolution

That doesnt change anything on the particle picture look, no effect on it.

But I put a Gaussian Blur (Quality 2 / Radius 4) on each , and that works fine for me. And doesnt stress my system so I can work with that for now.

Good to know. Thanks!!
