If so, how are you using it? What problem are you solving using the Sprite Cookie from the Point Light 2D? Using it like a projector.
If we removed the Sprite Cookie from the Point Light 2D, how would this impact your productions? Canât easily make a complicated shape of light.
YesïŒsome time I would use Sprite Light2D for a big shape like a big paper cut. I use to make a fire spark with Point Light2D and cookie because I can control the angle and radius. I would like to remove cookie and get better performance.
Thanks for the additional info. It would very helpful to see how controlling the angle and radius of the Point Light helps with a fire spark. Would it be possible to share an image of this?
Iâd also like to understand why you want to remove the cookie for the fire spark. How would you make it look like fire without a cookie?
Sprite Light 2D certainly sounds like the right kind of light for what you are describing.
The 2D team need to figure out where 2D features live. I missed this post due to the fact that I donât check the 2D forums since 2D lighting is an experimental feature and thus I figured would be asked in the 2D preview forums. Parametric Light2D
Are you using the Parametric Light 2D component? No, we use freeform lights when we need a shape.

What other preconfigured Freeform Lights shapes would you probably find useful? We feel freeform lights supersede all behaviors of the parametric light and parametric can be removed.
Falloff Offset parameter
Are you using the Falloff Offset parameter on any of the 2D lights? Yes!
If so, how are you using it? What problem are you solving using the Falloff Offset parameter? We primarily are using it as a way to control light direction of freeform lights. This can represent of day light shifting of the 2D light. So that as the time moves during the day the lights will shift their offset to simulate light shafts at specific angles.
If we removed the Falloff Offset parameter, how would this impact your productions? Weâd probably need to have unique shafts for every time of day. This would affect our workflows fairly considerably and increase the amount of time it would take to handle these types of lights.
Sprite Cookie on Point Light 2D
Are you using the Sprite Cookie from the Point Light 2D, parameter on any of the 2D lights? No
If so, how are you using it? What problem are you solving using the Sprite Cookie from the Point Light 2D? Although we donât use it in our current project. I could see this being useful to reuse a cookie at particular angles of light. Sure you could make a custom sprite light for every use case to achieve a similar result, but at a cost of needing to have custom light textures/sprites in memory. I feel you should keep the point light cookie around unless it has a perf impact.
If we removed the Sprite Cookie from the Point Light 2D, how would this impact your productions? N/A
Falloff Offset parameter
This is how Iâm using the Falloff Offset with the Freeform lights to simulate a fluorescent lamp. It helps to control the end of the light falloff and soften the borders of the shape:

Falloff Offset parameter
Are you using the Falloff Offset parameter on any of the 2D lights? Yes
If so, how are you using it? What problem are you solving using the Falloff Offset parameter? Preventing hard edges between lights, which important.
If we removed the Falloff Offset parameter, how would this impact your productions? Yes, it would have a significant impact on the lighting since it is used extensively, unless there is another manner of achieving the same effect. In any event, it is likely to require a lot of work,
Sprite Cookie on Point Light 2D
Are you using the Sprite Cookie from the Point Light 2D, parameter on any of the 2D lights? yes.
If so, how are you using it? What problem are you solving using the Sprite Cookie from the Point Light 2D? Cookies being used to create shadows that are important for the look of the game.
If we removed the Sprite Cookie from the Point Light 2D, how would this impact your productions? Yes, unless a viable alternative is provided.
Thank you all in helping us to understand how you guys have been using the 2D Lights, in particular, the Falloff Offset parameter. We are in the midst of jamming alternative ways to help achieve those mentioned outcomes.
We thought we would also mention that the soft edges of the lights could be controlled via the Falloff and Falloff Intensity parameters which you guys have demonstrated and both these parameters are here to stay.
@Ferazel , yours is an interesting use case which we would really like to understand it correctly.
Could you help to elaborate a little on how you use the Falloff Set parameter to achieve the daylight shifting effect?
It would be super helpful if you could provide any screenshot(s) to help us accurately understand your desired process or even the outcome. Thank you!
Welcome to the forum @Saeglopur1992 ! Thank you for joining the community!
Perhaps if you were to start a separate new thread and provide more details on your issue, it would be easier to understand and to assist you. Like what were you tweaking before it stopped working.
Basically, itâs a poor manâs light shaft. For tall windows that bleed light in the mornings, vs sunset we can use the same light but animate the offset to fake it like a window that is facing north an example could be.
Morning/Noon/Sunset
Not sure if this is the right place, but have you considered introducing 2D directional light and something like shadow falloff/cookie?
Let me explain the question/use case:
Right now, all the lights basically behave like point lights when it comes to normal mapping and shadows. Even freeform light shines from pivot spot, so that the shadow has always the direction from pivot of the light to shadow caster (though extended further from shadowcaster), wherever it might be. That doesnât feel very well when it comes to natural light sources which are supposed to be so far away that the shadow casting angle is basically constant, just like 3D directional light works. The same goes for the normals, which are lit from the direction of the pivot spot of the light. So currently thereâs no way to apply âdaylightâ on your normal mapped sprites, at least without excessive use of unnecessary amount of lights
The shadow falloff/cookie is meant especially for top-down projects where you can use them as sort of drop shadows extended from shadowcaster, but not for the whole length of the light, but just for preset amount. Or is there any dedicated drop shadow system for top-down projects in development?
So⊠Falloff offset has been removed in 2021. How can I achieve the same effect I explained above ( #10)?
I donât see any alternatives. As I explained back then, this will break all my light effects as soon as I upgrade URP.
I just upgrade my project from 2019 to 2021 and see there is a lot of things changed in 2d light, and basically, I canât achived what Iâve done in 2019. I use falloff offset and parametric light a lot to fast build scene with lights that has direction.
