You can do destructive modeling in Houdini. Simply model as you want, add a null and set it to “locked” (red on the node). Now you can delete all previous nodes.
This is the same as “delete history” in Maya.

Thanks for checking it out!

Be sure to read the installation instructions:

This shader uses it’s own bsdf reflectence function, that needs to be installed manually. To do so, right click on the OTL, choose “Type Properties”. Go to “Extra Files”, select “specular_eval.vex” and click on “Save as File”. Save it to:

C:\Program Files\Side Effects Software\Houdini 13.0.198.21\houdini\vex\CVex

Or for Mac:

/Library/Frameworks/Houdini.framework/Versions/13.0.198.21/Resources/houdini/vex/CVex

and the corresponding folder on Linux. Do the same for “specular_sample.vex”.

Let me know how it's working for you and if you need any improvements.

Hi

I created a shader, specifically for PBR. It's meant for complex and realistic surfaces. And is now ready for Houdini 13!

It's written in VEX and the code is open for you to use if you buy it.
