Weight paint issue, model is breaking, can't change strength

[FromOuterSpace]

as you can see at the edge where the weight paint ends it is completely breaking, how do i fix this? + the strength and weight settings are not working i can only use red (im guessing full strength) + as you can see theres a point near the front i want to remove the weight paint from there but idk how to, changing weight to 0 does nothing it still paints everything red. Is my weight pain tool just broken? How do I fix this?

So I need 3 things answered
1 how to fix the edge break
2 how to erase the red paint
3 why is my strength setting not working

What course is this from?
What lecture?

Close ups can be useful but not without all the panels screenshots too.

For each bone, you can paint/update/change the weight map.

But I see five or six bones fighting for the same mesh space.
All influencing each other. Hard to solve by hand.

Remove weight paint maps en use auto-weight painting while connecting the bones to the object.

For posing you can also use the sculpt pose tool. But only for static, non animation, poses.

You can, but it is assumed, especially if you do not give any information, that it is course related and therefore we could have a better idea of what you were doing, were aiming for etc. makes answering easier. People want to help but do not make it hard for us!
