It's really fast than not using “Multithread When Compiled”.
For example, “connect adjacent pieces node” is not-Compileable.
In the adjacent piece node, “compute_point_normals” cause not-Compileable.
So I exchange this to “attribute_expression” like same function which do “compute_point_normals”.
It looks fine when I check “Single Pass” in ForEach Sop block one by one.
But it cause error when I disable “Single Pass” in Foreach Sop block.
So, I debug “connect adjacent pieces node”.
In “connect adjacent pieces node”, “connect_nearby_points” has some code like below.
I debug “connect_nearby_points”'s code. So, I find pcimport function causes error.
Is there anyway to fix this? or replace to attribute vop sop?
I think it's houdini 16.0's program error. It cause segmentation fault.
I test this Houdini 16.0.671 in Ubuntu 14.04, and Houdini 16.504.20 in Windows10.
Both of them cause Error and shut down Houdini program.
I attach file, too.
