Default blinking sprites

I have been fiddling with some sprites, and when I hardware render them, they seem to be blinking, which is not the intension. For the moment I'm all out ideas of out what to do next. So here is the scene. Its a simple 4.5 scene. Maybe ladies and gentlemen, some have some time to say their 2 cents about whats there is wrong with it.


help much appreciated ...

and the sprites images
...

I had to cut some off the images away to fit them here, so the sprites will need a reassigning of the sprites, but the blinking should still be there.

Ok, now remember, I'm NO sprite wiz here so keep that in mind

I see 2 possible issues here:

1. First, a small one, in your 5 images that you are trying to cycle through, image new.3 is 256x256 pixels in size, while the rest are 512x512.

Maya might not know how to treat this, so it may be omitting it, or it may be too small to see, so it seems like it is blinking?
Not sure.....

OR

2. In your particleShape ApplySprite expressions, 2 particle shapes share this first int string:

int $firstImageNumber = .I[0];
int $lastImageNumber = .I[1];


Then, the remaining 2 share this string:

int $firstImageNumber = file2.startCycleExtension;
int $lastImageNumber = file2.endCycleExtension;

Maya might not know how you want to cycle through your images, or, maya might be having an issue with something along those lines maybe?

...Sorry I couldn't be of more help


On a side note, are yo trying to achive a "warp drive" type of starfield flythrough effect?

If so, have you tried using an omni point emitter emitting points with a pass ratio of 5 (like you currently have), and have the points emit towards the camera, in a cone shape?

Just one of many ways to do that.
(IF that's what you were trying to do...)

Lemme know if I helped at all, AND if you ARE trying to get that type of effect, I have MANY easier ways you could try to do this that have worked fo me in the past
