Title: CoronaCamera culling in CoronaScatter
Post by: Evan_Popilnukha on 2018-04-21, 09:52:00
Hey guys!
I have a really huge field with different type of grass(~10),leaves etc..which was scattered with CoronaScatter..And i was wondering may i optimize it..So i found romullus post https://forum.corona-renderer.com/index.php?topic=9728.msg62865#msg62865 (https://forum.corona-renderer.com/index.php?topic=9728.msg62865#msg62865)
It was like 3 years ago,so may be we already have a new method to make something like this..I mean without map,cuz i'm already using VertexPaint map for density to mix grass..
So any suggestions?
I know that the Forest Pack has this kind of feature..But..i dont wanna buy it just because of  that..I'm fully satisfied by CoronaScatter..except this cool feature :)

Looking forward,
Evan

Unfortunatelly camera culling isn't there yet. I think you could still use that method and retain your orginal vertex paint density map, you'd just need to mix them in composite or CoronaMix maps and plug into density slot.

Hi!

Thanks for your answers.

Was trying to blend Gradient Ramp and VertexPaint on  the  test scene first..it seems to be working fine.But if there is a possibility to remove scattered objects behind CoronaCamera (on Attachment) ?

-UPD

Just tried with only one scatter...It works a little bit strange..

Thank you,
Evan

Could you show your gradient ramp settings?

Just tried.One problem,with extra grass behind CoronaCamera has been solved.
But another problem is still here..I mean it removes a lot of grass at the bottom of the camera frame.Can i do something with it?

Thanks

Could you strip your scene of all assets except camera, scatter object and ground plane, save it to max 2016 version and attach to the forum message? I have very little time to try recreate your situation, but i could look at the problematic scene if you'd provide one.

Of course,will be very grateful for any help.As u can see it removes a lot of grass when tilling is 1,but when 0.9 it turns to a bit better way.(brushed in red where the grass is missing)but  a lot of grass behind the camera
and i'm a little confused :D
