Particle Object to Inherit Uniform Colour from Emitter

[Swest]

I have a particle system which is rendering as objects. I would like each of these objects to have a uniform colour. I would like the colour to be dictated by the underlying material of the emitter. I.e. if the particle is emitted from a red part of the emitter, it should be red all over, if it’s emitted from a blue part, blue all over.

I thought that this question would solve the problem for me:

Particle Color based on where the particle is emitted?
but it does not seem to work for me.

There are a couple of other similar questions. This one shows a solution where the emitter texture is mapped across the particle object — I want a uniform colour instead.

Can Object Based Particles Inherit Pixel Color Of Emitter?

@atom, Liero Cheers for helping to answer this continuous question. That project texture map is a kind of “hack” that I would think to do as well, cheers for showing this method very clearly. Like I have mentioned earlier, it is probably nicer if we can script it so that: particle instance become “LIVE” object ala RE:Ticular. get color of each particle and pass it on to RGB diffuse of each corresponding material. it would be nicer if the color of each particle can be tracked at every frame. …

This one seems similar to my issue:

Instanced particle objects: any way to inherit color from particle's parent object?

I’d like to use the color from a texture mapped to the body of a bird to influence the tint of each feather’s color. So far I have a hair particle system being created on a parent mesh, source emitting from its faces, rendering each particle from a referenced object. My hair particle reference object is a simple plane, with its own material that has a feather mapped to it. What I’d like to do is incorporate a texture or color from a material on my parent mesh to influence the shader node tree …

but the solution is that it is a bug specific to when the emitter has modifiers applied to it, which I do not.

Here is my simple MWE .blend:

Any help greatly appreciated.

Hello Swest,

i am at the same point as you have been nearly 2 years ago.

Have you found a solution to this? If possible without Geo Nodes cause i want to combine that technique with the Graswald or Botaniq addon.

thanks in advance
