You need to edit the file maya.env, which is described here: <a href="https://help.autodesk.com/view/MAYAUL/2024/ENU/?guid=GUID-8EFB1AC1-ED7D-4099-9EEE-624097872C04" rel="nofollow noopener">https://help.autodesk.com/view/MAYAUL/2024/ENU/?guid=GUID-8EFB1AC1-ED7D-4099-9EEE-624097872C04</a> [<a href="http://help.autodesk.com" rel="nofollow noopener">help.autodesk.com</a>]<br><br>Mine was completely empty, so I just added the line, as described by Bobcat:<br>HFS = D:\Production\SideFX\Houdini 20.0.625<br><br>That's obviously the path to my Houdini install—you'd change it to wherever yours is. Once I'd made that change, Maya loaded the plug-in without complaint.

Houdini to Maya HDA Attribute Paint
2024-02-05T16:08:27+00:00johnmather412164Correct. What you can do is open the Houdini Engine menu in Maya, go to Debugging and then choose View Assets in Houdini. This will show you how Houdini sees the Maya scene. You will then see the attributes that are being passed into the HDA that you can utilize.

Houdini to Maya HDA Attribute Paint
2024-02-02T16:26:39+00:00Jose_SAEZ411972Hi guys, im developing some HDAs for Maya, and one of those require to scatter some points over a surface, to do so im using an attribute to controll the density of points by painting influence areas(using an attribute paint sop).<br>So what i want to know is how to paint that mask in maya and transfer that attribute to the HDA.<br>The way i do it is pluging the attribute paint to the main input of the asset and typing the attribute name in one checkbox linked to a scatter node.<br>That's easy in Houdini but im not quite sure of how to create and link that attribute in Maya.<br>Any ideas?<br><br>Thanks in advance.<br><br>Jose<br>Pd: Here are some images of the Hda in Houdini and Maya.
