I am trying to create curvy trails through particles. However, I am getting straight lines when I use trails SOP. What should I do?

Revisit the tutorial, specifically the section on setting up the trail node.

Thanks a ton! That did it! However, the trails don't come out to be smooth. I used a resample SOP and that didn't solve it.


Then I used smooth SOP and it helped. However, it appears as if smooth SOP uses more memory than resample and I feel there's a way to create smooth trails without using either of those but I don't know how.



Moreover, I get these warnings in my DOP network. Why are they coming? I didn't change the source geometry at all.

Looks really cool! Actually the tutorial only covered using particles and collisions. It doesn't mention anything on trails. I'll check out other tutorials on trails once again. How did you change the colour of the trails on the ground to change with time?

Here's my method for trails with fixes for issues similar to yours. I think its fairly robust, and not too cpu intensive (the trail sop can get really laggy with high values):

Thanks Matt. Tried the pop replicate method. Works very well!
