How to use post-processing and tone mapping correctly?
As in the example, the background output color is incorrect and not white
Tone mapping in post processing affects the whole viewport and will indeed change the background color – you’re not doing anything incorrectly there!
You can adjust the colors with tone mapping in mind, or perhaps keep the background transparent and let the page background show through … but note that not all post-processing effects are compatible with transparent scene backgrounds.
Thanks for the answer, I have another question, seeing your previous work on custom keyframe animations, so I used your custom curves for a test experiment, but the expected behavior of it was puzzling, the first is that it is moving in the opposite direction, and the second is that the position of its movement is not the 30 I gave Use keyframes to customize interpolation errors - Questions - three.js forum (threejs.org)
You can see the difference in the case by quickly commenting on this line of code
@donmccurdy hi
Could you start a new discussion thread for the keyframe interpolation question? Would rather not turn this thread into a 1:1 on mixed topics, lots of others in the forum who can help and/or learn with a new labeled question.
