I created a thread about this in the main support forum but was told to repost here. I am trying to get this tutorial to work: http://blog.moondrop.no/2016/08/creating-colored-fog-in-a-2d-game-with-unity/ I managed to run this in a new project just fine, but in my main project where i want to use…

Create a Vector2 node. Plug in MinDepth into x, and MaxDepth into Y. Then plug the Vector2 into the InMinMax input of the Remap Node. For OutMinMax, put 0 and 1. Overall the remap is saying “convert the input value from position.z into an output value between zero and one, where MinDepth is zero a…

thanks, the color now changes smoothly and also the mainTex works as it should! for 2, i basically want to controll the “tickness” of the fog, aka the opacity also depending on the z axis. imo i need two gradients, one for the front from transparent to black → z=0 to z=negative-clampvalue (where i…

[image] KingKonXI: wouldnt i replace the color (red and blue) nodes with the actual gradient values? yes! that’s exactly what you should do. The gradient can replace lerp & colors, with Time corresponding to Lerp’s “T” input. not so sure I understand what you mean fully, but probably. A goo…

Thanks, I am still playing around with this, and it works almost as intended, but i only want the alpha of the gradient to decrease (and the color(=fog) to increase) the sprite itself should be visible 100% in all stages. Wenn connecting to the sprites (fragment) alpha the sprites opacity decreases…

[image] KingKonXI: I also noted, that gradient->sample gradient seems to output a fix value of the gradient ? If I understand you correctly, it has a ‘fixed’ value in this case based on its position.z so that’s just one value per sprite. That’s because you’re billboarding the sprites toward t…

i have just seen your reply. working on that now

understood with the single value, makes sense when its at a single z position. i might not need to seperate alpha at all, if i just want to tint the sprite its handled via the gradient itself since the sprites transparency will not be touched I minimized this to just one gradient, and i understand…

You really should be able to get it to behave the way you want by connecting the Remap into a Clamp with (0, 1), then directly into Sample Gradient’s Time and then outputting the that directly into the Multiply with the Sample Texture. The smoothstep, lerp and multiply nodes could be removed. Then …

2D Colored Fog Shader with URP (940916)

Unity Engine

ok some new progress:

i now have black in front, color, and black again.
its not completely what i want, but if the black in the back gets switched to the acutal color than its close.
