Octane Scatter texture map

Hello,

I try to project texture from an image on an Octane Scatter. I tried using several techniques but it does not work. The best result was obtained with Image Texture and Triplanar but I still can not get my texture in place.
Could you tell me what to do?
Do you know any intelligence resources about this?

Thanks for your help

Hey, thanks for this!
@bepeg, Ahmet - is this the only way to get a colored map onto the scattered objects? It is a working workaround, but sooo slooow :'/ (v4 XB2.1)
Hair is much faster in this special cases, also randomized color, but colormap as source would be best. Is there another, probably faster possibility in sight?
ThX!

How many instances do you have? And are they engage each others?
Please define what's slow? Rendering or somethings else?

Hair will take 10 sec. preparig before I can see the first rendering with map based colored ... strands? in viewport. 100.000 Hairs with 3 segments, krinkeled and knitted cones (don't know the exact english words).
That is fast to my machine for hair, but slow compared to your pure scattering object. scattering based on a b/w map, cones with 3 hight segment and 6 arround - but in white ^^

Now, compared to bepeg's method with InstanceColor node plus texture effector and based on particles scattering, this takes 30 secods and more to prepare and start rendering. But it is hard to compare, since I scatter the cones via b/w-map in scatter-object scale slot - so I have to use about 5 times more clones and more toget a similar effect. Probably thats the problem? May I send you the file if you have time for an eye on it?
And also viewport is very slow with this method. rendering itself is normally-fast.
