i just finished a pretty challenging scene setup.
figured out how to select only specific values of a vertex color..
i had previously set up a system where one object had certain parts vertex colored 100% red, 100% blue etc.. and i could change opacity of those parts based on that.
but being limited to 3 groups (colors) was too little.

so i set this scene (attached) where you can set whatever decimal space value of one color of vertex paint.
ie: there are 3 blue boxes in this scene.. one with all of it’s vertexes at 0 red, 0 green and 0.3 blue, the next box is 0.6 blue, next 0.9.

using the color ramp node, and selecting just those values.. i was able to control the boxes visibility
pretty cool!
i was so psyched that i had come out victorious after hours and hours of trying different things (greater/less than) etc…
so excited to implement it into my project which i’d made it for…
but yeah…
no dice…
won’t work in verge3d

the scene shows up.. just the opacity doesn’t work for some reason.
bummer.

anyway.. those are the error messages i got, up there.
the blend file is attached.
(also i typed “vector paint” i meant “vertex paint”

all the nodes in this pic are supported. i don’t know what went wrong.
