Orbolt HDA's open website instead of being placed in flowchart Sept. 14, 2018, 11:54 a.m.

Recently whenever I attempt to place any Houdini nodes that I downloaded from Orbolt it opens the Orbolt webpage for the asset instead or dropping the node!
Strange behavior, does anyone know what might be wrong and how to fix?

Redshift on a mac Aug. 30, 2018, 4:10 p.m.

Houdini is not the most stabile program in the world, add to being on the mac version, add to that rendering in Redshift, add to that hacking your mac to support an eGPU and there are lots of places for shit to happen. Despite all of that I'd never want to go back to my CPU based Mac renderer – the speed these GPU's give is creatively liberating.

If I were to buy a new computer I would go PC. I'm in the midst of a big 3D project and finding myself hitting lots of bugs (mainly in redshift) I suspect some of these bugs are are mac-specific. Often they require annoying workarounds which partially negate the time savings I'm getting from my GPU's.

To summarize: eGPU rendering on a mac, still a big thumbs up. But not a panacea.

RBD constrains June 28, 2018, 3:28 p.m.

To fix certain parts in place but keep them in the simulation I first create a group that includes the points that represent each shard of glass that can be impacted.
Then I make a point integer attribute on that group called “active” set it so that all members of the group have the value active==1, all others active==0
The riged body solver will recognize the active attribute. Points where active==0 will be colliders, but not simulated.
Im also using the glue constraint network off the shelf to hold all the shard in-place until they're struck by the bullet.
