this is fantastic, thank you!!

unfortunately i get an error with a custom ice node. Per_Point_Array.dll
although it still works.

Code: Select all

# WARNING : 3000 - Invalid port type specified for Custom ICE Nodes.
# Port Name: Attribute
# ID: 0
# Invalid port type: 276480
# WARNING : 3000 - Invalid port type specified for Custom ICE Nodes.
# Port Name: Array
# ID: 201
# Invalid port type: 277504
# ERROR : 2384 - This port type(s) is incompatible with other ports of the same constraint map:
# <Node: Per_Point_Array>
# <Port ID: 201>
# <Group ID: 201>
may it have something to do with this?
"...the output port was using the same same context
ID as a "singleton" input. So using two context IDs solved it..."

Yeah, it's an error that only pops up in 2013/2014 (and possibly 2012). Loads fine in 2011
Back when trying to fix it SI would complain even if all ports were given separate constraint maps. Any and all combinations short of cutting the extra ports would result in the same error, so I'm just going to leave it as long as it doesn't cause any actual problems.

Granted, chances are I'm overlooking something painfully obvious. Would expect it to throw the same error in 2011 though.

Thanks!, just in time to test some dinamic Muscle System ideas I was having... great timing men , thaks a lot, you probably save a lot of us HOURS of work :)

Can the strands collide with things other than strands?

The framework includes a node that turns the edges of a mesh into strands, which you can collide with.
It also includes the stock strand collision setup, which lets them collide with mesh faces as usual.

Have a look at the Dynamic-Mesh-Collisions sample scene

I remember seeing some tests for this stuff on Vimeo years ago. It's fantastic that you finished it and even more fantastic you are sharing it. People like you are helping to keep the golden age of ICE going. Thankyou.

Another glaring issue... No Linux compile? :-\ It's too bad as I'd love to use it in production at work (in Softimage in Linux.)

Do you have plans of releasing the source?

I am planning a complete rebuild to go along with a set of more advanced hair modeling tools I am working on, as such I would rather this monstrosity not spread any further :)

Alas, it is going to take me a while to get to it, as the modeling toolset takes precedence.

I am afraid you are going to have to wait :(

This looks very promising. Thanks a lot for sharing.

Cheers!

This is great and it seems to work perfectly for hair once the emitter is set to segments instead of capsules.

Is there a way to taper the ends?

Hey Roughy,
your strand collision framework is really amazing!
is there a way to enable selfcollision and collsion with other objets at the same time?
cheers

You can just add a second Collide Strands compound directly beneath it, and use that to collide with any other strand geometry: http://i.imgur.com/1S97000.png

At least it seems to work. It's been a long time since I've touched this plugin, and I have no recollection of trying this.

Pardon the belated reply; I don't visit these parts very often anymore.
