Hi! I am using Houdini 16.5.268 and HtoA 2.2.0. I tried to import the lighting ass file by arnold_procedural in Houdini, but it didn't show up in the viewport. Also I tried to render it, but it came out with Error that showing "Error Command Exit Code: 1".
The ass file was working fine in Maya, and the Arnold render was working ok without Arnold_procedural node.
Am i doning something wrong? or there are other way to import lighting in HtoA?
Error Command Exit Code: 1
That's not an Arnold or HtoA message. Can you get an Arnold log?
@Stephen Blair
Yes! Thank you for replying.

When you export the lights, you'll need to export shaders too.
Thank you! I tried to export it again. It was better right now I think...but still not rendered anything...
It was showing this:
00:00:13 144MB WARNING | node entry "standard" is deprecated, and may be removed in the future 00:00:13 149MB WARNING | rendering with watermarks because of failed authorization: 00:00:13 165MB ERROR | [ass] line 10419: node "MayaFile" is not installed 00:00:13 153MB WARNING | aborting render setup: received abort signal
If you want just lights and their light filters, then that ASS file has too much in it. Or are you using a texture on a quad light? If so, then since you're using the MayaFile node to load the texture, you'll need to add the MtoA shaders to the Shader Search Path in HtoA
Hi
Working fine here, but you have to do some manipulations to force the ass file showing in the viewport.
when you look inside Arnold_procedural /File contents, and hit the node info or middle mouse in the node for some reason you get a warning that tell you something like "Unable to read ass file " or "Please specify a geometry file"
Just unlock the node arnold_procedural (Allow Editing of contents), go inside and click one bye one Switch_bbox, bounds, edges and OUT_bbox. this solve problem viewport.
last Put a path in Procedural Path
render
Thank you! I tried to do that in Houdini, but still not showing the bounding box...and the warning still there...it seems that the contents node doesn't read ass file...
I'm using aiPhotometric lights in the scene. I added the path in HtoA and rendered it, it came out with other warning...
"00:00:00 47MB WARNING | unable to load dynamic library C:/solidangle/mtoadeploy/2018/shaders\synColor_shaders.dll: The specified module could not be found. 00:00:00 51MB WARNING | rendering with watermarks because of failed authorization:"
Or I added it in the wrong way?
You can ignore that, because you don't need synColor.
Or you can copy the mtoa_shader dll to your HtoA install.
Thank you Stephen! Since I updated Houdini to 16.6.323 and Arnold to 2.2.2...And it works now....
Thank you Rachid! Since I updated Houdini to 16.6.323 and Arnold to 2.2.2...And it works now....
