Quixel Color Rendering Error

[Borzi]

Hey there! Before I begin to describe my issue, please keep in mind that I am a beginner at 3D modelling and am still learning. The problem I am encountering is that I have installed the Quixel Colors tool to texture my model in Quixel. The problem is that once I try to render the material map, I get the following error in the Houdini Console:

Traceback (most recent call last):
  File "C:\Users\Scott\Desktop\Quixel SUITE 2.0\quixelcolors\lib\QuixelController.py", line 129, in <lambda>
  File "C:\Users\Scott\Desktop\Quixel SUITE 2.0\quixelcolors\lib\QuixelController.py", line 149, in openDDO

    raise hou.OperationFailed("Invalid parameter name: " + parm_name)
hou.OperationFailed: The attempted operation failed.
Invalid parameter name: vm_renderengine
 

I am not sure that I can identify the problem and hope that someone can help me with this! Thank you in advance for your efforts.

Hi Marc,

I'm not familiar with the Quixel Colors tool. But I downloaded it and took a look at the code. I believe it is trying to make a baketexture node in the "/out" context and then trying to set the "Rendering Engine" parameter on that node (vm_renderengine). For some reason that "Rendering Engine" parameter doesn't exist and so the script errors. It looks like houdini 15.5 changed the baketexture node so that it no longer has a "Rendering Engine" parameter. So that would explain why the script is failing.

So I think the solution for you would be to use houdini 15.0 instead of 15.5, at least until the Quixel Devs update the tool.

Hey MirrorSword! Thank you very much for your answer. It does appear that this was in fact correct.  The problem had to do with the Quixel Colors execution script. As you mentioned, the tool was not compatible with 15.5 due to a change in the renderer. The tool will make a “baketexture” and all you have to do is go in manually and “render current frame” it using the “baketexture” node in your “out” view.
