Hey, im using post processing to improve realism in my scene. This works more or less. The main problem is that dark colors have a weird behavior when SSAA is enabled. Here a before/after demo. Left is with renderPass, GammaCorrection & FXAA, right is with SSAA, GammaCorrection & SAO. See the black …

Postprocessing seem to overall alter the colors and contrast. Maybe try adjusting gammaFactor in the original renderer, lower it a bit? https://threejs.org/docs/#api/en/renderers/WebGLRenderer.gammaFactor (May be related: https://github.com/mrdoob/three.js/issues/18451 ) Edit: I may be wrong on th…

[image] mjurczyk: Edit: I may be wrong on this one, but GammaCorrection pass should always be at the end of the postprocessing pipeline - moving it may also help? Nope, FXAA should always be done in the final color space. So it usually comes at the very end of the pass chain. @Fluqz Do you r…

i am terribly sorry to hijack this topic with a small question, but this looks stunning for something that’s presented on the web. could you recommend any resources that go into baking? the ones that i have seen don’t seem to yield results like that, not even close. yours looks actually real. …

I’m not sure why adding or removing SSAA would cause any color issues like you’re showing but I notice that you’re setting the renderer outputEncoding to sRGBEncoding and also adding a gamma correction pass. You should just be doing one or the other: this._renderer.outputEncoding = THREE.sRGBEncodi…

I do not use baking at all, because every part of the scene is dynamically positioned. I have multiple lights that I tried to configure to have a very soft shadow. Also using the SAO to generate a Ambient Occlusion effect works quite well, but it costs a lot of performance. For that reason I have tw…

[image] Mugen87: Do you really need SSAA and FXAA? Isn’t it sufficient to just use FXAA? I forgot to mention that I only use one at a time. In code the passes were disabled, but that wasnt clear enough sry. I changed the description. Left picture is with renderPass, gammaCorrection & FXAA, t…

[image] Fluqz: using the SAO to generate a Ambient Occlusion effect works quite well, but it costs a lot of performance. Could you use SSAO instead? Also, you can try SMAA instead of FXAA.

Here is a jsFiddle which shows the problem. OnMouseUp the Shark gets way darker and has less gradient. Also see the cube reflection from the spotlight. The gradient is also getting smaller @looeee I tried the SSAO before but it didnt look good at all. I will look into the SMAA, thanks

Lowering SSAA.sampleLevel to 1 enhanced greatly the color problem, while keeping AA. Adding a background color to the scene stopped the background color changing problem. See here : https://jsfiddle.net/oj8914ph/ [Jun-03-2020 09-07-23]

Does anyone have an idea where this comes from? https://jsfiddle.net/f3qksgnj/
