Hi! :raised_hand: So basically Im running into an issue where Im getting an inferior result using EffectComposer. Renderer + .outputEncoding = THREE.sRGBEncoding: (correct) [image] EffectComposer + RenderPass + GammaCorrectionPass: (ugly) [image] Is this the expected outcome with some textur…

It seems the issue can be fixed if the internal render targets of EffectComposer are created differently. If you enhance the following section: mrdoob/three.js/blob/515f212281cf5735415c4c74bda562d507ae3198/examples/jsm/postprocessing/EffectComposer.js#L26-L31 var parameters = { minFil…

[image] DolphinIQ: Forgive my ignorance, but I feel like there is no way this behavior is intentional. The colorspace conversions are giving me a headache :sweat: I’ve run into this problem before when dealing with post-processing, and I confess, even after several days of studying color spac…

Some more considerations for post processing: some passes need to be in linear space (before tone-mapping) and some need to be done after. Some can be done before or after but you’ll get different results (e.g. vignette). Outline effect looks like it has tone mapping built in (probably incorrect?) …

[image] DolphinIQ: Would Takahirox’s PR fix that issue? AFAIK, no. It’s just the idea to move post-processing into the core. In any event, I don’t think I would add tonemapping or gamma correction automatically at the end of the pass chain in EffectComposer. At least there should be a flag t…

[image] Mugen87: In any event, I don’t think I would add tonemapping or gamma correction automatically at the end of the pass chain in EffectComposer Hmm, yeah on further consideration this suggestion is contradictory with the need to do some passes before tone mapping and some after. Howeve…

Well then, what would be the reason for the ugly effect on the second image? Because color-wise it seems like it is converted well, it’s just that those pixely (almost 8-bit looking?) artifacts are showing, almost as if precision was lost? Im not very knowledgeable in the internals of THREE.WebGLRe…

Um, I don’t know so far why these strange artifacts occur. This is definitely worth investigating…

@DolphinIQ unfortunately I can’t get your example to run. THREE.WebGLRenderer: WEBGL_compressed_texture_astc extension not supported. THREE.WebGLRenderer: WEBGL_compressed_texture_etc1 extension not supported. THREE.WebGLRenderer: WEBGL_compressed_texture_pvrtc extension not supported. THREE.WebGLR…

Hi @looeee , could you please replace one line in three.module.js from this PR WebGLTextures: Add support for CubeTexture with compressed textures. mrdoob:dev ← Mugen87:dev29 opened 03:51PM - 11 Jan 20 UTC (UTC) …

So it was related to precision after all :hushed: It reminded me a little of those old space games arts Thanks a lot guys! This was a really instructive thread :pray: :bowing_man: Managed to get selective bloom working for my game! [image] Intrstingly enough, the precision still wasn’t as good…

Can you please demonstrate this with a live example or some code? There might be an issue in your app elsewhere.
