follow path question

[dan_j]

Hi guys, does anyone know how i can get a transform sop at geometry level to follow a path at object level?

Cheers

i usually do it with linking the transform sop to the NullObject which is following te path at obj level

just link each parameter (SRT) using origin() expression to get a global transform of the null

like origin("","../../null1","TX") ... (TY, TZ, RX, RY, RZ, SX,...)

maybe it can be done easier and more elegant

for entire sop solution you can also take a look at carve sop, plug your curve in, change to extract mode, copy your object onto it and animate the first U parameter

however you wont get rotation this way

Thanks for that Anim, that works really well for what i want to acheive.

Nice one

nice dan_j

you can also acheive this without expressions by objectmerge

giving you the ability to separate your object from the trail

that way it may be easier to manage later

Thats even better. Cheers Anim

Here is a small HDA I made a while ago when I needed an object in SOP space to follow a curve. Might be of some help.
