Facing Issues while loading xgen procedural.dll in standin.

As per documentation, Arnold provides path(dso) and data attribute on standin to allow loading custom procedurals and their flags but while trying to load xgen_procedural.dll in path and passing required flags in data attribute it's showing me below error.

WARNING |   [proc] aiStandInShape: don't know how to load .../xgen_procedural.dll

Any suggestions for what I might be missing?

dso? You're looking at the old Arnold 4 documentation. The procedural nodes loads ass files only. Something like xgen_procedural is an xgen_procedural node.

Hi Stephen,

Thanks for the quick response...

Adding further clarification to make myself clear, I am using Arnold 5 mtoa 3.x and inside the data attribute (inside extra attribute section) of standin, I am calling below flags and values to pass my xgen file.

setAttr ".data" -type "string" "-debug 1 -warning 1 -stats 1  -frame 75.000000  -file E:/RnD/xgen/workflow_development/AiStandin/sphere__collection.xgen -palette collection -geom E:/RnD/xgen/workflow_development/AiStandin/sphere__collection.abc -patch pSphere1 -description description -fps 24.000000  -motionSamplesLookup 0.0  -motionSamplesPlacement 0.0  -world 1;0;0;0;0;1;0;0;0;0;1;0;0;0;0;1";

Then inside the path attribute(which internal name is .dso) I am calling specified procedural.dll file. (File browser gives the option to select ether Arnold archives/Arnold procedurals file type.)

setAttr ".dso" -type "string" "C:/solidangle/mtoadeploy/2019/procedurals/xgen_procedural.dll";

And Yes, As you mentioned it used to work fine in Arnold 4 but I am not aware how to replicate the same for Arnold 5.

Basically, I am trying to avoid baking ass files sequence here. instead, I was trying to pass procedurals flags and required procedurals path.

I would appreciate the help..!!

In Arnold 5 and later, xgen_procedural is a node. So this is what is exported:

xgen_procedural
{
 name /collection/description/descriptionShape
 visibility 255
 matrix
 1 0 0 0
 0 1 0 0
 0 0 1 0
 0 0 0 1
 id 3738019217
 data "-debug 1 -warning 1 -stats 1  -frame 21.000000  -file C:/Users/Stephen Blair/Documents/maya/projects/default/scenes/xgen_archives__collection.xgen -palette collection -geom C:/Users/Stephen Blair/Documents/maya/projects/default/scenes/xgen_archives__collection.abc -patch pPlane1 -description description -fps 24.000000  -interpolation linear  -motionSamplesLookup 0.0  -motionSamplesPlacement 0.0  -world 1;0;0;0;0;1;0;0;0;0;1;0;0;0;0;1"
 declare dcc_name constant STRING
 dcc_name "descriptionShape"
 declare xgen_shader constant ARRAY NODE
 xgen_shader "lambert1"
 declare irRenderCam constant STRING
 irRenderCam "false,38.357384,38.285717,70.352417"
 declare irRenderCamFOV constant STRING
 irRenderCamFOV "54.432224,36.288151"
 declare irRenderCamXform constant STRING
 irRenderCamXform "0.877983,-0.206371,0.431922,0.000000,0.000000,0.902297,0.431115,0.000000,-0.478692,-0.378512,0.792201,0.000000,0.000000,0.000000,-88.806236,1.000000"
 declare irRenderCamRatio constant STRING
 irRenderCamRatio "1.500000"
 declare xgen_renderMethod constant STRING
 xgen_renderMethod "1"
 declare ai_mode constant INT
 ai_mode 0
 declare ai_min_pixel_width constant FLOAT
 ai_min_pixel_width 0
 declare xgen_multithreading constant BOOL
 xgen_multithreading off
}

A standin is a procedural node, not an xgen_procedural node.
