Hi, this is something big, it takes a very small amount of memory, CAN have uvw coordinates, and its fast!

(info taken from fstorm facebook)
If we could uvw  a corona scatter will be awesome

I saw this too on facebook. Would be INSANELY useful to have.

That F-Storm dev is a machine, putting out features daily.
Vray who?

It looks quite impressive, but can you guys share some ideas how this could be utilized in real scenes? (not just demoing the feature)

If we could Uvw a corona scatter it would be possible to create rugs (very easy and low memory, fur is not for EVERY kind of rug)
Uvw maped grass or anything else.

The Corona team have been putting up new builds every night also..........and have been for years...........

that Fstorm-GeoPattern looks just like uvw mapping in hair n fur and in forest pack doesnt it?

i was writing almost the same words as yours but you post it first nicely. :)
i remember when corona was in alpha stage, many people saw Ondra release fixes, changes, new features everyday and they wasnt really wrong when they thought he never sleep.. i even thought he wasnt from earth

btw, i got a stupid thing in my head, if ChaosGroup bought Corona is really real so it will not be possible to if one day Corona do it to fStorm too in nearest future. :D

Exactly what I thought when I first saw the demo.
Plus I'm getting a bit tired of people always asking for the brand new feature presented by others, but it's just my point of view. That doesn't mean any roadmap never needs to be adjusted but come on ...

First real world example I can think of would be making wicker chairs. Model the base geometry of the chair, then model a patch of wicker and use Geo pattern to tile/deform/weld the wicker to the chair mesh shape whilst keeping the memory footprint to that of the small patch of wicker.

Second example: chain links/chain mail.

I might be wrong, but i think it's the same guy (Karba?), who did create vraypattern and Fstorm/geopattern.

If geopattern uses UVs for distribution, then something very similar can be achieved with Corona scatter, except for texture colour derived from distribution mesh.
I'm not Corona Team member. Everything i say, is my personal opinion only.

Indeed, it's the same guy. He developed it when he was working at icube but it's not the owner of the software.

I'm a bit disappointed by some people's reaction... This is extremely useful! If that can be done with Cscatter then show us an exemple, i'd be curious to see that! Pls recreate that curtain with Cscatter and show us the result.

No matter if you are close or far from the object, it will always look better than an opacity mapped texture and it's cheaper in term of calculation. Look at the curtain, simple material, no memory cost, anisotropy resolve by itself etc etc... I was a user of Vraypattern and I would kill to get that feature in corona! Basically it replace displacement for patterns and it's way cheaper, can be viewed from both sides, no need to mess with geometry shifting etc...

I take my words back. I tried to replicate that curtain example, but i failed. Corona scatter strictly follows distribution mesh normals and doesn't care about scattered mesh continuation. And it eats RAM quite significantly - i scattered 8 billions pieces and it ate majority of my 16GB RAM. No match for Vray/Fstorm-pattern :]

@Fluss: Great examples. Would absolutely love to have this in Corona, or something similar :)

i hope it wasnt my reaction :)
i just prepared things to try it with cScatter but i see romulus post and cancelled my try immediately. then, i think this "GeoPattern" will be a great feature to have in our corona.
