How to fix the position of particles for each frame?

particle

(Michael George) #1

Hi,
I’m using a keyed particle systems and turbulence to transform one word into another.

I’ll render this video in many sessions but I can’t do it because the animation of the particles changes when I close and re-open the file.

Ex: I’m on frame 100. When I render it, it gives a specific view or image. When I close and reopen the .blend file and render the same frame again, It gives a different look or a different image. This way I’ll not be able to render it in many sessions because the animation is not continuous.

I tried to bake the animation but I can’t find the cache tab because I use keyed particle systems.

Thanks in advance :slight_smile:

You must activate the cache on your particle System.

Thanks for the reply. I read the whole page but I still don’t know what to do. I cannot find “cache” tab because I’m using keyed particle system. Does activating the cache make the cache tab appear again?

I m not in front of my compiter…answering here on my train time. But yes , from my bad memory, If cache options are ghosted, activate it and bake.

You can bake only particle system with physics, if all systems are keyed, then I don’t get why you are using turbulence field, as it doesn’t affect this type of particles. Make sure target system use physics

Thanks for your the reply. I wish you nice traveling. Actually, the cache option is not ghosted or grayed-out. The tap itself disappears when I use keyed particle systems.

Thanks for the answer. Maybe my question wasn’t clear but I’m talking about the video in this thread and turbulence field gives a beautiful effect. I don’t wanna lose it. I just need it to be calculated for one time only and then save the calculations to have the particles in the same position whenever I open the file.

I meant that you can’t find cache, because you aren’t looking for it in proper particle system. You need to cache objects, which use newtone type of particle systems.

so is there any other idea to have fixed position of the particles for a given frame?
