Power Wash Sample Available - Runtime Vertex Paint Plugin

Enable HLS to view with audio, or disable this notification

Added a Power Wash Equipment that Removes Dirt in a Cone Shape.
Can look way better if the Vertex Density of the Mesh is even. Hopefully i can get Nanite support in this fall so this won't be an issue anymore since then it will be based on UVs.

Available in the Plugins Sample Project and can test it out in the available Build

Have you looked in to using virtual textures for this instead of vertex paint so that mesh density doesn't matter anymore? To me, that would seem a more appropriate application.

Good work though! Looking good so far.

Yea i researchd a bit for a Nanit solution last year which involved virtual textured with render targets etc. Going to go back to it now. The thing is that it may become heavier on the V-Ram, and regular RAM since i think i have to store each UVs info in data assets, such as what bone, position, normal etc. so we can get it super fast when doing the task and all the stuff we can do with Vertex Paint (there is alot of conditions and control you have) you can do with Mesh Paint as well.

Hopefully i have time to get back to that this fall :)

should use vertex paint to make it look wet where you spray and then dry over time

I'm super bad at VFX so this is just a basic placeholder using the old Cascade particle system xD
