Substance Integrations - Houdini - Substance and PDG
 on: June 20, 2019, 09:12:10 am 
Hi,
While looking for a way to have multiple variations of a Designer material inside Houdini, I found PDGs. It looks like a good alternative to the lack of keyframing support for Substance materials in Houdini. When I create a Wedge TOP node to add variations it all works good, I can even see the variations in the viewport licking in the Wedge dots. But then I use ROP Fetch to render and the images came out without the Substance material at all. Both with OpenGL node and Mantra node. However if I render directly from those ROP nodes (not through the TOP/PDG network) it works properly.

It looks that PDGs is not passing the material at render time or something like that. I get this issue in Linux but not in Windows.

Thanks

You can give PDG a try. I created a wedge node, then a rop and it worked very good as an alternative of keyframing parameters.

Hi,
I'd like to ask the opinion of staff and users regarding the best workflow for this task. I need multiple viewport renders from different points of views (animated .fbx camera) while the material's parameters change every x frames.

I tried first to use Houdini (my main tool) but first, I cannot seem to animate the substance exposed parameters, and second it is too slow.

Now I am looking into using the Automation Toolkit, but I am not sure there is a way to set viewport point of views from .fbx camera.

Should I try Unity? Does Substance allow parameter key-framing there?

Thanks!

I change to SubstanceToMantra_Experimental.cfg and it's working properly.

Hi,
The output opacity from Designer works well in my Houdin viewport, but it doesn't work rendering with Mantra. It appears there is no connection to opacity in the SubstanceToPrincipled.cfg so I added this:
      "opacity": {
        "opaccolor_texture": "%map%",
        "opaccolor_useTexture": "1",
      }

But still no luck. I am on Ubuntu, Houdini 17.5 and latest version of Designer.
Thanks!

Hi,
The installer script doesn't work for me. I also tried to copy the files into the /opt/hfs17.5/dsolib folder with no luck either. Can you help with where to put the files?

Thanks!

Hi,
How can I tweak the viewport settings to get the maximum quality when using a Substance shop material? I tried a few settings in the Display Options but I get always the same 'preview' resolution.

Thanks!
