Hi,
I am trying to use the Vertex Animation Tool to export a Fluid sim to UE4 but I keep getting the following error when trying to export the textures.
Python error: Traceback (most recent call last):
File “”, line 3, in
File “CPROGRA~1/SIDEEF~1/HOUDIN~1.268/houdini/python2.7libs\hou.py”, line 17710, in getPixelByUV
return _hou.CopNode_getPixelByUV(*args, **kwargs)
OperationFailed: The attempted operation failed.
Failed to retrieve pixel information.
I have tried reducing the number of polys and checked that I have point normals, but I keep getting the same error. Anyone got any ideas what I am doing wrong?
Thanks
Graham

We have fixed our problem
On the Houdini shortcut select properties. Then Under windows compatibility tab switch on Run this program as an administrator.
You should now be able to flip-book without crashes!

Hi
I'm not hitting swap, i have about 50% RAM free. I read on another thread about using the OpenGL ROP. I tried this and it works ok, so its one solution, but I would love to get Flipbook working as I have been using so much.
Also, I never had this problem before H14, I have a Qudro K4000.
cheers

Hi
I am trying to make a Flipbook in H14 but it keeps crashing at random points. I get this message:- License: Hserver communication error
I've never had this happen before H14. It does this at work and at home with Apprentice addition.
I am trying to Flipbook a meshed FLIP sim from cache.
any ideas?
thanks

Hi
I was wondering if anyone was able to help, I am trying to create a fluid tank that moves along with a boat. eg Add particles to one side and remove from the opposte side. I have done something very similar in realflow (28seconds in):-

I have seen a similar effect in houdini:-

I can't figure out how to do this, only been using houdini for a few weeks. Does anyone know how to do this?
Thanks

I have added a wind force to the velocity field of the whitewater which is working however it affects the foam and bubbles as well as the spray. Is there another way to do this?
Thanks

Hi
I was wondering if anyone was able to help, I am using the new whitewater solver in houdini 12.5 and I am getting some really nice results. I want to add some wind and curl noise to the spray particles to add more realism but I cant find where you can add the nodes. Houdini wont let you add nodes within the whitewater graphs. Does anyone know how to do this?
Thanks
