manojit ghosecustom particles vanishing abruptly just before exiting camera's frame

hi everyone,

got stuck with something!

i have a TC particular setup... made the particles freeze with the physics factor and prerun value... and i am using custom particle to make a 3d grid and make my camera simple pass through these particles.
everything is as desired but:
however whenever a particle is close to camera... it suddenly disappears instead of gradually passing off the frame.
this is happening more is the particle is coming head on to the camera.. the ones which are a bit away from the centere of the camera are stayig a bit longer. but even they are popping off abruptly.
my visibility option newar values are at minimal 1 for visibility and 1 for fade out.

please need help urgently!

thanks!

Manu,

I am not sure what the problem is? The particles just disappear when the get to a certain point? It sounds like you have one of the near vanishes turned up, but you said you set it to 1. Try resetting the vanish to the default settings and see if that clears up the problem. You should be able to pass right through a particle and have it stay on until the camera is past it. If you still cant figure it out, I could check out your comp and see what is messing it up.

dear mark,

thanks a ton for offering to help in the first place, i really appreciate it...frame 18-19,19-20,34-35,49-50 and so on... is what i am talking about.
i tried fiddling around with the far and near distance value, but no help.
here is the file: http://www.4shared.com/file/145711527/27acdea9/grid_folder.html
please let me know if you find any solutions!

thanks once again

Manu,

You are welcome. I am not sure why it is clipping, but you are right, it is. Do this, change the particle type from textured polygon to sprite. That should fix the problem. It does not look like you are rotating the camera, so you dont have to worry about the look of the 3d layers. This seems to fix the problem. I don't know if this is a quirk of the new software from Trapcode, but I will look into and see what I can find out. Let me know if this fixes your immediate problem.

Best,

Mike Park
