Full ESM build, minified and gzipped.

🌳 Bundle size after tree-shaking

Minimal build including a renderer, camera, empty scene, and dependencies.

Related: #29156

some chaining methods have been removed in favor of tree-shaking

Some TSL operators can now be chained and others cannot. IMO, this results in a confusing API.

Users will be annoyed that they can't remember which ones can, and which ones cannot, be chained.

Can we solve this -- even if it hurts tree-shaking somewhat?

@WestLangley Can you list the TSL operators you are currently using that are no longer available? This might help me get a second understanding of the issue.

@sunag I rewrote my code to accommodate this PR, but I believe this was the original set.

bloom
sepia
posterize
dof
saturation

There’s also more here: #29238.

Also I would say that all of these feel quite niche and case-specific, making them more suitable as third-party nodes.

And if a developer wants to use them as chainabable it is still possible in user-land through addMethodChaining.

Maybe these nodes should be addons instead of being in core? Maybe that'll help to understand what's chainable and whats not.

Maybe these nodes should be addons instead of being in core?

Would we then have two imports? Or would it be something else?
Some nodes that are in the core are not chainable like texture, uniform, vec*, ...

import { texture, uniform } from 'three/tsl';
import { saturation, posterize } from 'three/addons/nodes/TSLAddons.js';

Or something like this...

import { texture, uniform } from 'three/tsl';
import { posterize } from 'three/addons/tsl/display/posterize.js';
import { saturation } from 'three/addons/tsl/display/saturation.js';

I think I need more one day to review some items in this PR 😇
