Are you guys using Renderman NC with Houdini NC? Or does Houdini need to be commercial / indie in order to use Renderman NC?
Thanks

That's an excellent fix! Transforming to camera space was the key difference. Thanks Scott

I tried adding a rest normal also, but had no luck with this. Do you have a simple example file? Thanks

I have been playing with the recently added UV triplanar projection VOP which is really nice and gives some great results.
However, I am having difficulty in getting the projection to “stick” to an object - the projection always seems to evaluate the X, Y, Z world axes.
I have tried adding rest position in SOPs and VOPs, but have been unsuccessful.
I have attached an image illustrating the problem - when the object is rotated, the values are mixing. I would like the top and sides to always retain pure R, G, B colors.
If anyone knows how to remedy this that would be great.
Thanks

Hi
I would like to be able to have an area of high intensity on an object which is animating through 3D space. I have already used normals, incident and dot product to get the camera's facing ratio. However, what I need here is slightly different.
There will be a fixed point in space that applies intensity to the side of the object that is facing towards it. The intensity could be a color attribute value.
I have tried using attribute transfer which is somewhat useable but not so useful when the object is moving and tumbling.
Any help would be appreciated.

Hello Sidenimjay,
Thank you for your informative reply! You broke these down in a way that is making more sense to me now.
If I understand correctly, the FLIP system is a voxel grid that is using vectors to determine the position of each particle at the next frame based on the previous frame's values?

Hi all,
Bit of a junior question here.
I'm just wondering what the difference is between all these terms (FLIP, particles, Pyro, etc).
I am wondering this because I've seen many different Houdini artists that are using different methods for creating FX. For example: particles for smoke, or volumes for smoke, or pyro for smoke, particles for FLIP, FLIP for particle / smoke advection, etc. It's all a little confusing.
If I wanted to create say a smoke plume or cigarette smoke or something. I'm not sure how I would go about approaching it. If these terms were a little clearer to me I could attempt to tackle it.
I am aware that there are various shelf tools that do this stuff for us. However, I would first like to just get my head around these different techniques at a basic level.

Hi everybody,
I am having a lot of trouble installing non-commercial version of Houdini on my Mac - had no problems at all on Windows.
Whenever I try to open Houdini, the License Administrator pop up always gives me this error:
“ERROR: Invalid machine name”
Does anyone know why I would get this error message?
Also, when running the License Administrator separately I get these errors:
“License server code: (not running)”
“License server version: (not running)”
Any help on this would be awesome.
Thanks!
