Dear reader

Im building a massive env for a film, and I have to find efficient ways of working in short time.
I found using packed geo for layout design to be a simple but great option to quickly try different env concept design with artistic control. Is there a way to scale the packed geo? (the points)

cheers

Edit sop and copy sop.
Or edit in Lops.

If memory serves you can pack objects that are already packed. For example you can use a copy to points to instance some packed windows and doors to their appropriate locations on a building. Then you can pack the entire building including the windows and doors you just instanced. The only downside is the opengl display will only do one level of unpacking.

Thanks, I remember now you could also scale packedprim using VEX


vector scale = fit01(rand(@ptnum), ch("min"), ch("max"));

matrix3 transform = primintrinsic(0, "transform", @primnum);

matrix scalem = maketransform(0, 0, {0,0,0}, {0,0,0}, scale, @P);

transform *= matrix3(scalem);
setprimintrinsic(0, "transform", @primnum, transform);

there was a bug yesterday why the edit sop refuse to scale my packed prim, have to relaunch Houdini, no need to go by Vex primintrinsic!
