[UNITY] clouds and lighting (particles)

Yadoob · Oct 2015

Hello,

We've just started a new project about a flying charracter. I made some clouds with shurik'n and a basic shaderforge shader with transmission :

The main issue comes with the lighting : point light doesn't work but directionnal does.

Is there a workaround for this issue?

did not try it myself but I stumbled across this a while ago:

Hi, thanks for you answer kio !

I test that method but couldn't get a proper result(the attenuation was sharp instead of smooth) and it seems to get the same problem reverse : it works with point but not with directionnal

.

I tried also basic vertex lit which get a nice result with point light..but don't work with directionnal neither.

could you have 2 directional lights, 1 for your scene and then one on a different render layer just for you clouds? that way you could angle it to get a nice read on your cloud shapes? also if you add a normal map input to your particle shader you could get some puffy rounded extra detail into each particle perhaps thats worth an experiment?

haven't they changed the particle system to worldspace recently?

You have no light attenuation node feeding into your multiply which has your light colour and diffpower. Directional has no attenuation.
