, yes , we are just trying to optimize some really big scenes here, so we are trying to avoid these IFDs with loads of points. and yes we can call it nested instancing

Hi
I have a question regarding point instancing, I have cached points which I instance geo on them (disk based with a string).
Is there a way to make this work on a farm without putting in the points into the IFD, kinda like delayed load the points and instance on top during render.

IMHO Yes.I don`t have one shot where I have not written at least a single line of vex. I am not a mathematician either.

Mari non-commercial version is the best tool for texturing, if you are little savy with python, you can automize conversion etc very easily.

instead of using the group bounding use this in a wrangle you will get some more boost
convert the shape to vdb like daniel said and connect it to the second input of wrangle
and
float in = volumesample(1,0,@P);
if(in < 0)
removepoint(geoself(),@ptnum);

thanks man, we are not on 16 yet, but I am sure I can find a workaround based on this…

Hi,
So I have a question that I think my shot benefit greatly. So I have this enormous river I need to make, which I plan not to do with flip.
But It makes S shapes etc, it has a visible flow to it, so obviously ocean is a good start for this, but I need to find a way to comb the wave direction.
So initially I tought, I am just going to make a vector volume field and use that some how in ocean spectrum to override the direction or whatever i can make sense of.
In spectrum node there is a calc_amplitude vop which has winddir attribute which converts into a vector2 field with x and z.
So I am trying to figure out, how can I manipulate this to inject my own path for waves……
anyone??
thanks
tim

15.5 was working just fine, so I just copied the ones from the .env file to h16.

Technical Discussion » Ocean Spectrum Custom Combed directions

Hi I am trying to understand why i am not able to replace the direction parameter with a custom velocity vector field
So inside oceanspectrum there is a volumevop calc_amplitude_for_normalize, which has a link to Direction, inside that vop
winddir value is converted into a radian and the resulting x,z vector values get fed into Philips Spectrum
So I assumed, I could override the last node that is windvector with a custom vector volume to have curved motion or something similar, but it does not seem to work.

Usually I end up saying, use whatever software you are comfortable with to deliver the shot, but I honestly think, apart from animation (because I have no Houdini animation experience) , there really isnt a reason to use any other software then Houdini imho.(convert from maya since 2010)

I think what he means is also how to just generate a deep pass without having the rgba a primary, I would like to know about this as well

we just did a exact test on 15.0 and 15.5.532, EmbeddedGeometry P in DOPS does not update on 15.5 comes out as it was on creation frame.

test was done on debian linux, with no GUI. these additional nodes are for computation only and you do not need to run houdini with UI, thats why you get the openGL error, what you need is to run the nodes via hbatch command from terminal(CLI)
