Using own attribute for mountain sop falloff
habakuk replied to hampuseh's topic in General Houdini Questions
something like this? mountain_falloff.hip -
if both geos have the same pointcount and pointorder you could use a point_wrangle: 1. create point wrangle 2. pipe animated mesh into input1 3. pipe simulated mesh into input2 4. add the following code: v@P = lerp(v@P, v@opinput1_P, chf("blend")); 5. click that little icon on the right hand side of your code text box that says "Create spare parameters..." to create a slider now you can blend between both versions and keyframe it.

alternatively you could use VEX. 1. create a measure sop (to measure the perimeter) 2. create a primitive wrangle with something like the following code: //do this after a measure sop #include <groom.h> float factorPerPolygon = fit01(rand(@primnum), .5, 1); adjustPrimLength(0, @primnum, @perimeter, @perimeter * factorPerPolygon); in above example each curve will be randomly refit between 0.5-1 times its original length.

erase part of mask in Heightfield (mask paint)
habakuk replied to anicg's topic in General Houdini Questions
just append another heightfield_drawmask SOP, set "Combine with Existing" to "Subtract" and mask off areas you want to remove. -
how about doing it in two steps? 1. create bubbles sim, and cache it out 2. use cached geo as a collision geo for the second sim

attached a super basic sample scene. hope this helps. reverse_rbd_fracture.hip

would it be easier to do the whole thing in reverse? 1. break object in to pieces 2. let it fall apart and force it onto a pile 3. then reverse the cache?
-
you could just use the ray SOP with 'direction' set to 'Vector', e.g. {1,0,0}

Beginner's question: how to exclude object from render?
habakuk replied to roarke80's topic in General Houdini Questions
check the 'Objects' tab in your ROP parameters. you can define 'candidate objects' or also force objects to render regardless of their visibility in the viewport. -
hi, Is the download link broken or is it just me? thanks! EDIT: sorry, it was me. all good!
