Anyone know what "Use Asset Object Transform" does? Feb. 11, 2018, 6:17 a.m.

“Use Asset Object Transform” is probably only useful when the asset is an Object asset. An Object asset has its own world transform, which isn't exported to Maya by default. Enabling that option will export the Object transform into Maya.

In the case of a SOP asset, Houdini Engine creates a dummy Object node, and puts the SOP asset inside. However, this Object node is always at identity. So when this transform is exported to Maya, the asset looks like it's always at zero.

I see your geometry has the “shop_materialpath”. There was a performance bug when outputting string attributes. This was fixed in 16.0.785 or later. You could test if this is the issue by deleting the “shop_materialpath” attribute in the asset, and see if there's any speed difference.

Another potential slowdown is when the output geometry from the asset tries to preserve the input Maya geometry's locked/unlocked normals and soft/hard edges. I don't know if this is happening in your case, because this depends on the input geometry from Maya. You could test this by deleting the “maya_hard_edge” and “maya_locked_normal” vertex attribute in the asset.

Turn on/off some asset parts Nov. 24, 2017, 9:46 a.m.

Using a switch node would be the way to do it. Many people use the switch node to turn off and on parts of the network.

Maybe another approach is to use multiple asset It's also possible to connect multiple assets together. This means you could have a separate asset for each stage of your network. Then, you'd connect them on the Maya side.
