I created a gaslinearcombination node and set the Destination field as vel, and in the combine operation I set to multiply source1: friction and source2: vel.
friction is a custom scalar field created by me, with a 3D noise.
The gaslinearcombination doesn't work as expected.
On the other hand, a simple gasfieldwrangle with the following vex code: " v@vel *= f@friction; " does the trick.
Why isn't the gaslinearcombination working?
