As much as we love automation here, there are some tasks that just have to be done by hand. Things like picking the right shader for every part of a cad model or finding the right orientation for 3D scans. So can we integrate these manual edits into our topnets as well? In this Video Chris shows ...

FOREWORD: We think this should be common knowledge, so we decided to make this part of the premium course publicly available.
It’s finally come so far – we’re accepting that we can’t (or rather don’t want to) write every complex algorithm out there ourselves in VEX. Enter Python....
The time has finally come! We will add Python to our PDG toolset and gain a lot deeper access to Houdini with our node trees. Let’s use PDG to create nodes, change parameters and push buttons!

Like probably a lot of people, Chris has been playing with Unreal over the past months. So since Houdini Engine has a new plugin for UE4 and APIs are still super fun to play with, why not try building a setup that let’s you turn any point on earth into a game map. Just by entering a latitude an...

We've been awed by Kohei Nawa's Pixcell artworks: http://kohei-nawa.net/works/pixcell - and of course we thought this would be a walk in the park to rebuild in Houdini. Of course it turned out there's slightly more to it ...

Does your 3d print take to much time? Why not try printing virtually then! In this video Chris shows you how to (ab)use a software originally created for 3d printing to add a unique stop motion effect to your animations.

It's time for a new course - and Mo has been looking for a topic that'd allow him to bundle together a few of the more involved setups he built. So "Advanced Setups" it is. How original.
In this premium course we're gonna dive into more elaborate Houdini setups, using VEX, a bit of math he...
It's still space time here on PDG101. We finish the setup from last episode and take this as an opportunity to explore automated comping as well using COPs.

PDG is all about working faster and one vital aspect of this is creating digital assets. So in today's episode Chris shows you how to turn the last setup into a custom TOP node and how to rebuild some core features of tops using file tags.
After our latest free tut one of the first questions that came up was “How do you render additive particles in engine XYZ?!” – luckily 2021-02-25 13:53:31 +0000 UTC View Post

Render managers like HQueue or Deadline can be a huge help in rendering large projects. But they can be quite difficult set up and, if you're using only one machine, a lot of features are no use to you.

Got tons of files on disc, you need to process? Let's automate this using tops!
In this video, Chris Kopic creates a batch processor in tops that takes stl files from threedscans.com, polyreduces them to a more manageable size and bakes textures to preserve small details.
