Re: Houdini 2 Soft Q - how to write/read Houdini attributes in XSI?

2016-10-11 Thread Morten Bartholdy 
So if I find the shaders in the Houdini installation I can put them on the 
server and use that path in XSI!?

Apologies for the noobish question - I am not the Houdini guy here and I have 
not used that option in Arnold yet.

If so problem would be solved.

Re: Houdini 2 Soft Q - how to write/read Houdini attributes in XSI?

2016-10-10 Thread Cristobal Infante 
Hi Morten,

Don't think it should be so complicated from the houdini side at least.
Obviously the R&D will be worth it depending on the amount of shots you are
doing.

Dop import is the node in Houdini that imports the data from the dop
network (simulation node).  There is a mode called "Create points to
represent geometry" this will give you a point per piece when using packed
geometry.

Also have you considered exporting an .ass secuence?

Best,
Cris

Re: Houdini 2 Soft Q - how to write/read Houdini attributes in XSI?

2016-10-10 Thread Morten Bartholdy 
Hi Christobal,

Arnold in XSI, and it is exactly a licensing issue, plus we would like to be 
able to do this for future purposes too - XSI will live a long time here. I get 
the part about just moving the particle data and using XSI instances. I am not 
sure we have the tech skills to make it work, but will look into it. Dop import 
- do you mean to extract points in Houdini or is that an ICE node?

Thanks for the tips so far - doesn't exactly look like a walk in the park 
though :)

Morten

Re: Houdini 2 Soft Q - how to write/read Houdini attributes in XSI?

2016-10-10 Thread Cristobal Infante 
Hi Morten,

What are you rendering with?

Sorry I don't know exactly how to transfer the attributes but it should be
possible with alembic?
I've never went back to xsi to be honest ;).

In terms of workflow, ideally you will export only center points from the
legos into xsi. You can use a dop import, and choose only to grab center
points to retrieve them.
Each point would have lego type, lego color attributes and then you would
instance in xsi your lego pieces. If you try to export the geo, you will
probably clog the pipeline and go crazy.

I agree with Jordi, life is so much easier when fx/rendering are done in
houdini,  however is good to be adaptable.
Even in big studios lighters have to use Maya/others because of licensing
issues (not enough houdini licenses) or simply the team .

Best,
Cris

Re: Houdini 2 Soft Q - how to write/read Houdini attributes in XSI?

2016-10-10 Thread Jordi Bares 
This is exactly what I was trying to clarify on a previous post, the package 
that does the VFX should become the backbone or else you will have to support 
this custom data export on both sides and it can become a lot of work, doable 
no doubt, but a lot of work.

You may want to investigate using Disney Partio as it has BGEO support and this 
may be the best route.

Hope it helps
