Houdini engine Maya slow Nov. 24, 2017, 10:47 a.m.

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.

Does the Houdini asset take input geometry from Maya?
How many polygons is the output geometry? What attributes are on the geometry? There's some overhead when converting geometry from Houdini asset into Maya, so it won't be as fast as inside Houdini.
If you could post a .bgeo of the output geometry, I can test if it's slow for some reasons.

Which Houdini and Maya version are you using? There was a few performance fixes recently, so you could try out the most recent daily build.
