Rain - possible?

[Ma-Shell]

Are you using any other posteffects? If so, the order in which they are executed is important. It looks like in the first picture your image is darkened after applying the rain and in the second the darkening happens before applying the rain.

no, i tested it with no post effect too. The same effect then

[macklebee]

If you are using a trigger based on collision, the effect is being added more than once to the camera post effect stack. You need to add a boolean check to prevent the effect from being added more than once.

 

example:

Script.rain = false

...

...

...

function Script:Change()

if self.rain==false then

self.rain = true

self.camera:AddPostEffect("Shaders/PostEffects/Rain.shader")

end

end

It is solved thanks to Macklebee

Here is a try with inside rain collision, I made today:

 

 

Edit

To make this I just let about 200 or more box with Mass set to 1 with invisible material falling over the player in a randomized area: This will be used as shape for roof collision.

Attach a sprite /billboard with the rain Material. Then an emitter at collision()/position for water splatsch.

After colliding just put the same box over the player again and again.....

 

The problem I found is that after 10 minutes or more it will be "Error: Run out of lua memory"

I checked that the game RAM would be bigger and bigger with time.

 

The material applied to the sprite seems to be essential in this. Seems that using a alpha texture is unfortunately too expensive.

I used finally a very thin sprite with a default material shader Model/flat/default - Alpha setting + Z-sort. Seems to be the less expensive for best graphic results.

 

Edit:

Solved with collectgarbage() added in main()

Now it looks like this:
