This is old topic, but asked frequently, so just wanted to point out SideFX Labs (former Games Tools) has also very clean and easy to use tool for creating curves from edges based on edge group called … well … “Edge Group To Curve”.

One more thing - when you had everything working and suddenly node like “Attribute Blur” SOP (or any other OTL using OpenCL SOP inside) throws similar error for you, I noticed that in most cases when you restart Houdini the error goes away. If not, try the above solution.

Hey Mike, I still cannot get motion blur to work the way I'm doing it. Could you please point me in the right direction? Should it work and I missed something or I'm doing it completely wrong?

The mesh has changing point count, so won't work this way, right?
I would imagine I need to have velocities read from Houdini, write them into some channel (I used color), and then apply them in UE4 using “Previous Frame Switch”. This setup works if instead of a Color brought from the “VAT Material Function” node I use color constant - eg. I use vector 0,0,10 which blurs very nicely my points upwards.
But whenever I use the exported Color being my velocities from Houdini nothing happens. Even when I crank up the values 1000x still the blur is none.
I must be missing some step.

Hello,
I have successfully managed to get animated flip mesh export to UE4 using VAT. Could anyone tell me though, how to get motion blur to work on the mesh?
Cheers,
Beny

Thanks!
Hey hey,
Have you found out what was causing the triangulated mesh for you?

Hello,
I'm sharing it here since I had a pain in the bottom with solving this one half of the morning.
Basically whenever I ran Vellum sim on my Windows 8.1 laptop I got an error “OpenCL Exception: clCreateProgramWithSource (-34)” in Houdini Console and the sim did not run. I googled for an answer and found similar problems OpenCL related. My Houdini help showed “No Configured OpenCL Device”. I tried setting multiple env variables like HOUDINI_OCL_DEVICENUMBER=1 (0 -too),
HOUDINI_OCL_VENDOR=“Intel(R) Corporation”, HOUDINI_OCL_VENDOR=“NVIDIA Corporation” , HOUDINI_OCL_DEVICETYPE=CPU etc.
Ok - to the point - my solution was:
1. Edit the settings file "C:\Users\\Documents\houdini17.0\houdini.env“
2. Add this line anywhere ”HOUDINI_OCL_DEVICETYPE=GPU“.
DONE! So simple, yet very frustrating when you don't know it.
ps. For newer Houdini users - easy way to test if things work is to use Houdini Command Line Tools and run command ”hgpuinfo -c“. If it lists your device it means it works. If it throws something like: ”Could not create OpenCL device of type (HOUDINI_OCL_DEVICETYPE): GPU (…)" means it won't work.
Cheers,
Beny
