Particles - Sub UV, rate of random image change

I would like to set rate of ‘random image’ change to be random value instead of a constant. I need DistributionFloatUniform, but ‘random image change’ does not provide distribution type. Is there a way to do it some other way?

Have you tried adding a SubImageIndex, then set the distribution to uniform with your image range?

I.E. if you have a 36 frame sequence, your uniform distribution should be 0-35. Set your Interpolation method to Random or Random Blend, set Random Image Changes in your required module to the value you want to speed it up/slow it down.

I did try it before, and uniform distribution did not seam to work either random or linear. I’ll try again to make sure if I set it up right the first time and let you know. Thank you for posting answer!

I tried it again and failed. Particle set up as your suggestion came to same result as setting Interpolation method to setting interpolation method to Random, which it looked like Random was overriding whatever is set in SubimageIndex. Another try, setting SubImageIndex to uniform or uniform curve AND interpolation method to Linear just switched images erratically without any control to speed. What I want to achieve is varying speed of image change.

I used additional emitters set at different rate, emitting where first emitter’s particle dies. It’s close enough to the look I wanted for now. Still, let me know if you find out how to do this with one emitter. Thank you for the help.

There is currently no way to set the random image change to a value other than Constant. Using multiple emitters as you mentioned would be the only way to do this currently. There is no plan to add this to Cascade at this time.
