rendering as few frames as necessary

Recommended Posts

Hello all,

I am rendering out some images which get posted back to my server and I'm having issues with the function firing more frequently than it should.

I have two loops; loop1 & loop2... which should call the createThumbnail() function 9 times in total and then stop rendering. However, if you have a look at the console you will see that it gets called 36 times in total (1+2+3+4+5+6+7+8).

Here's a PG:

I think I'm doing something silly & obvious, but can't see it... any help would be very welcome.

Thank you,

That's just the index of the loops.... not the number of times they are called.  This is doing what you're expecting.  Well it's just calling it 8 times but that's probably due to the AfterEvent not firing the way you have the code.


What are you trying to achieve?  It seems a little over-complicated.

Here's a tweaked PG.. the numbers in the blue circles on the previous attachment are duplicated lines on the console. ... this shows what I thought, that for example 'loop1: 3 loop2 3' is called eight times.

I am ultimately trying to achieve a series of images to be saved to my server; loop1 might be an array of camera locations and loop2 might be an array of material colours.

This is due to the fact you are registering more and more tasks on the observable on each loop and they are running async.

so on 1 1 you put a callback in the observable runninng next frame 

on 1 2 you add a new one so 2 captures ill happen next frame and so on...

Why not using smthg more direct like ?
