program not valid with latest three.js

[aiden-jeffrey]

I'm seeing this error trying to use your library on a recent three.js release (r157):

three.module.js:19999 THREE.WebGLProgram: Shader Error 0 - VALIDATE_STATUS false

Program Info Log: Fragment shader is not compiled.

  1588: 	material.anisotropyB = tbn[ 1 ] * anisotropyV.x + tbn[ 0 ] * anisotropyV.y;

Any idea what I can do to fix this? Should I just use the version of this that ships with three.js?

[aiden-jeffrey]

Looks like this was the PR that broke things: mrdoob/three.js#26805

[aiden-jeffrey]

I didn't want to use the three.js version mainly because they don't expose lightColor in the constructor.

Had a stab at applying that diff to your shader: #40

@aiden-jeffrey your fork doesn't seem to work for me in three 159, running this fails

 npm i aiden-jeffrey/three-csm#aiden/three-157

any updates?

I just used the three.js fork of this in the end. I'm sure that the PR I linked is most of the way there, but I couldn't get the shadows to render.

Just tried your fix with three.js 162 and I do have shadows!

How you did it? I mean three-csm working with three 162.

I have this problem.

I forked CSM (actually just copied the files from the threejs samples: CSM.js, CSMFrustum.js and CSMShader.js)
Then I applied the fix from @aiden-jeffrey and I use my local version of CSM for now.

The file with the fix is here: https://github.com/ebeaufay/UltraGlobe/blob/master/src/csm/CSMShader.js
