I am getting a GL ERROR :GL_INVALID_OPERATION : glDrawElements: range out of bounds for buffer when my BufferGeometrys index attribute is a Uint8Array. It does however work with Uint16Array.
I created this jsfiddle which demonstrates the problem. Go down to the line noted and change the type from Uint16Array to Uint8Array to see the issue.
#8358 seems similar but was resolved.
The offending code looks to be these lines in WebGLIndexedBufferRenderer such that when it encounters Uint8Array it does not set the size to 1 but 2 instead. It seems as though THREE.js just doesn’t support it. Is it intentional or is there some other reason?
Tested
- r82 and r83dev

- Windows
- Intel Integrated Graphics
@WestLangley sure, it’ll be about a week before I have time but I’ll make a note of it 🙂
