VideoTexture's colorSpace not working on Emissive channel

vis_prime · October 10, 2024, 2:19pm

When a videoTexture is applied on emissiveMap of a MeshStandardMaterial , SRGBColorSpace does not work and it always stays in Linear color space

In this demo jsfiddle.net

The same VideoTexture and an ImageTexture is applied on

emissiveMap input of a MeshStandardMaterial
map input of a MeshStandardMaterial
map input of a MeshBasicMaterial

& Gui controls colorSpace of both

(look at the top right plane in this video)

Guessing this a bug ?

### Description When a `videoTexture` is applied on `emissiveMap` of a `MeshSta…ndardMaterial` , `SRGBColorSpace` does not work and it always stays in Linear color space ### Reproduction steps - create videoTexture - set it to SRGBColorSpace - Apply video texture on emissiveMap of MeshStandardMaterial - make emissive color white and diffuse color black so its simulating a real life 'display/screen/tv' - notice the video looks washed out as its displaying in linearColorSpace ### Code ``` const videoTexture = new THREE.VideoTexture(videoElem) videoTexture.colorSpace = THREE.SRGBColorSpace const emit_mesh = new THREE.Mesh(planeGeometry, new THREE.MeshStandardMaterial({ color: 0x000000, emissive: 0xffffff, emissiveMap: videoTexture, })) scene.add(emit_mesh) ``` ### Live example In this demo [jsfiddle.net](https://jsfiddle.net/n34jm8c0/7/) The same VideoTexture and an ImageTexture is applied on `emissiveMap` input of a `MeshStandardMaterial` `map` input of a `MeshStandardMaterial` `map` input of a `MeshBasicMaterial` & Gui controls colorSpace of both ### Screenshots (look at the top right plane in this video) https://github.com/user-attachments/assets/416f3fd8-515c-46f2-9131-74aae4c66c1c ### Version r169 ### Device Desktop ### Browser Chrome ### OS Windows
