Title: Scatter - Distance - Change of Color
Post by: mrsacan on 2022-07-22, 11:43:05
Hi,

First of all I'm still using Corona 7 (Hotfix 1), so this is not a up to date problem probably. I don't know if still happens latest version of Corona.
This is more like a question rather than requesting help. I'm just curious, does scatter become buggy after some distance? Or am I missing something?

Let me give you some examples, material color become more white if you keep move away (a simple Corona Physical Material with a Corona Bitmap, Roughness 1.0 by the way, so no reflection) :

It's a simple grass scatter, at close it's green, but become brighter

Same material, this is from a top view

Same material, again, it's a top view

You are using a texture with opacity, right?
If so, you are probably experiencing this effect: https://support.chaos.com/hc/en-us/articles/4528578885649-Objects-with-opacity-maps-are-becoming-gray-when-they-are-far-away-from-camera-

It's a jpeg but I'm using unwrap uvw (it was a transparent grass texture png, I saved as jpeg but still have white background),
I tried to keep face inside of green parts but I'm going to try with a green background.
TIL.
