Feature Request - Distance based activation/deactivation to save performance

[lordrex34]

I recommend an option to activate/deactivate the Kawaii Physics nodes based on Distance (in meters probably).

For example if I set "KawaiiPhysicsDistanceLimit = 100" then the system would disable if the distance is higher than 100M. When the distance decreases to 99M it activates again.

Hi @lordrex34 ,
Do you know LOD option of anim node? This should help in most cases, and has the added benefit of working with other LOD elements.

thanks!

Thanks I understand that - though what I really meant is:

• I use kawaii physics for Hair & Cloth
• I want to stop Hair physics after distance 2000
• I want to stop Cloth physics after distance 1000

Can this variation be done via the LOD Threshold @pafuhana1213 ?

[pafuhana1213]

It is possible depending on the LOD settings of the SkeletalMesh. However, it is a bit tedious to set it up, so I recommend updating the Alpha of the KawaiiPhysics node according to the distance. This method is flexible and versatile, so it should solve almost all problems.

Does the processing stop (and save resources) if the alpha is zero?

Hi @jtbiddle

The initialization process runs, but other update and evaluation processes do not run.
It's in Japanese, but I've researched it and will share the results.
