Scaling The Bullets Dynamically

[@vvolfart]

Hey, just a quick question. Was just looking at the h19 file - the code in the geo wrangle. Should't the last 2 lines of code also be inside the for loop? (float myscale = fit(falloff, 0, 1, 1, 1.4); @pscale *= myscale;) If they are outside it seems only the falloff of the last influence point will be used.

I enjoyed the tutorial. However, the box size does not increase in Houdini 19 version. It seems that a function in the dop network has changed, what should I do?

Heyhey, thanks for letting us know. I just uploaded an updated version for H19. Turns out things got a bit easier, now all you have to do is scale up a pscale-attribute on the primitive's template points. Cheers, Mo

@@Entagma Thanks, enjoyed your tutorial as usual. I was facing the same issue, thanks for the resolution. :)

@@Entagma yes, however the scaling of pscale on points prior to Copy to Points attribute, has 0 effect on the DOP network, DOP reads the initial frame and ignores any pscale changes

To make this work A) convert scatter sample points to 1) sphere + copy_to_points (using scatter points) 2) vdb from polygons set it to Fog B) in DOP network get rid of any transform references,and instead of using point(1,"P",i); use volumesample(1,"density",i); it does not need fit call since 0 means (far away) and 1 means near by. C) instead of setprim.. use @pscale *= newscale; Note: u must set & import pscale into DOP network, so it has a starting @pscale to work with

This is great! I was wondering how to scale the packed primitives and the collision geo in a more "fluid way", like the scaling now is sort of controlled by the frequency of the enable solver ( or am I missing something?)

Did you ever figure this out? I'm trying to do the same with an emitter
