I feel like I’ve already asked some obvious questions but I’m still learning.
I have a simple stars shader that works ok with the default rendering pipeline:
even though the pipeline darkens it, its still manageable.
but when I use the default rendering pipeline with HDR textures set to true:
the scene is suddenly brightened and the shader starts looking odd.
and for other shaders as well:
I have no clue what’s going on. Is there some way to stop this? Or should I forget about using HDR textures?
this is the playground: https://playground.babylonjs.com/#74E01A#5
If you turn HDR on on your pipeline yopu are supposed to output pixel in your shader in linear space (and not gamma space)
In this case we recommend to add a pixel conversion at the end of your pixel shader to output the pixel in linear space
For the background you can call scene.createDefaultEnvironment() which will create a skybox with a BackgroundMaterial that will fix the background color
That was fast. thanks for replying. I’ll look into that right now.
I researched on it and found that opengl uses sRGB color space by default. then I researched more and found this: GLSL-Color-Spaces/ColorSpaces.inc.glsl at master · tobspr/GLSL-Color-Spaces · GitHub
and its working well:
thanks for your help.
