htoa trouble -- rendering with motion blur geometry deformation


Recommended Posts

anyone have any experience with htoa?
I'm having trouble exporting proper motion vectors to .ass
my error is saying is that my "vlist" (A point array of vertices. Multiple keys are supported to obtain deformation motion blur.) and my "nlist" (A point array of vertex normals. Multiple keys are supported to obtain proper deformation motion blur.) dont match
..
command line prompt reads ERROR | different number of motion keys in vertex/normal arrays: normal keys: 1, vertex keys: 2

I have no idea how to fix this.. Previously I was transferring point velocity from my point cache to my geometry with attribute transfer. Mantra was rendering the geometry perfectly fine with motionblur

As you can see in the attachment my geometry has point velocity. When I subdivide the geometry, the velocity vectors update with the polycount increase so its definitely connected.
Any ideas?
thanks for your time!

Hi Shane

First where is this

"As you can see in the attachment my geometry has point velocity"

 

also what build are you using ?

 

Arnold properties ?

like in the snap shot

Hi Mangi, thanks a bunch for your response

I'm pretty sure the current build installed is htoa-0.7.1 for houdini 13.0.401

 

According to solid angle user guide I "Add(ed) Arnold Properties" and the arnold tab showed up on my geometry sop, I have both the transform keys and deform keys set to 2, and the same settings set in my arnold rendering node
