I've been playing around with the substance plugin and I fear i don't know enough how COP's work to fix this myself. People have had similar issues but none of their solutions seemed to work for me.

For example:
SOP: Geo File (some FBX) -> Labs Substance Material -> OUT Null
Stage: Scene Import Material (Import SOP Geometry ticked ON) -> Camera Lights etc... -> Karma Render set. -> Karma

In the view port everything works, but when i render to Disk/MPlay I get the error:
'Unable to fetch texture file from COPs: op:/obj/Asset/Substance Node/copnet/DIFF'




I know that you could export the Substance Archive Textures to disk but I want a workflow where i can output variations for a client and just send them off without having to bake out a bunch of textures.

Hi.

Being dump here. If I am animating APEX characters in SOPs what is the best workflow to animate a camera.

So far I have been in Solaris witha SOP create to make characters and then either referencing in a usd camera or using a lop camera.

Use the layer attribute create in COPs to add the savepath attribute. Set a temp path for each texture and then Karma will save them to disk for you before rendering.

Probably best to make a new thread for this but you can do one of the following:

• Have your camera above the SOPCreate in LOPs.
  
• Set the SOPCreate's "Show LOP Stage in SOPs" parameter to a LOP node with access to the camera you want.
  

Either of those will make the camera show up inside the SOPCreate.
