any methods to bake camera motion blur for spark FX

Recommended Posts

Hi, I am looking for how to bake camera motion blur in SOP level. 

For instance, there is a spark or simple pop sim. After siming, I can create spline sparks with trail SOP as baked motion blur looking. However, I am not sure how to bake camera motion blur on the top. I guess we will use NDC transform which I know how to do it, but also still need $F+1's camera and $-1's camera's positions to calculate differences.  If anyone knows how to bake camMB to spark/spline trails, I appreciate it, thank you.

dleonhardt, thank you so much!

That's very unique method!! I never expect to use loop block, instead of using VEX/python.
