Seems like the Substance COP has been debugged in the very latest release of the SideFX Labs tools - at least I can at last get the Base Color channel out of it. The Substance SOP hasn't yet been tweaked to use Base Color.

Will look more as time allows.

It seems so strange, Substance being a large procedural system and Houdini being the same, that there would be so much issue with them working together when Unity or Unreal work perfectly with them. I would think that Houdini, of all systems, would work great with it.

I agree.

The current situation is this:

1. If your SBSAR has a Diffuse channel the Substance Material SOP should work

2. If it only has a Base Color channel the Substance Material SOP will not work

3. Currently doing a rename of the Base Color channel to C in a COP set-up as you've done doesn't seem to work - I don't know if this is our fault(s) or a bug.

4. One of the guys working on the SM SOP knows about all the above and is looking into it. He's going to add a Base Color channel to the SM SOP and hopefully sort out the rename problem/bug.

Sorry I can't help directly. Any UVs will let your see the material, even incorrect ones like an Orthographic projection for a test. If your object goes pink but you can see the other channels are being respected then you've come across the problem.

Anyone know what might be causing the striping in my simulation, shown below?
