Gaea Labs toolset error March 19, 2022, 6:46 a.m.

Hi all,
cannot for the life of me figure out how to get the gaea node working. Can get parameters up if xml is generated but get an unhandled exception error everytime. Tried using legacy node types and still no joy. Have all correct licenses and tried on two separate machines and the same. Latest labs toolset installed and latest houdini production build 19.0531. Also Gaea is up to date. Please Help Me!!
cheers, Matt

Reading attributes in Ue4 Material Editor Oct. 2, 2021, 4:19 a.m.

Does anyone know of a way to read additional attributes from an HDA in unreal engines material editor?
Currently using all vertex color channels and Alpha but would like another channel if possible.
Tried with custom attributes but cant get it to work. Any help would be great

River Tool July 25, 2020, 9:42 a.m.

Been creating a tool that will create a river for a terrain. A part of my network makes the input curve always go downward by running a simple previous point position wrangle through a for each loop:

vector pos = 0;
pos = point(0, “P”, (@ptnum-1));
if (pos.y < @P.y)
{
@P.y = pos.y;
}

This works just as intended, however, only when the points of the input curve are below the origin (@P.y=0).
I have got round this by transforming the curve before the loop and transforming back by attribute (@xform) afterwards but can anyone explain why this was necessary? Cant for the life of me figure out why.
