Blender Secrets - Knife Project (New Method!)

Knife Project has been featured in a couple of Blender Secrets videos before, but recently since Blender 2.93.4 the way it works has changed, making those videos somewhat obsolete (sigh…) So! Here’s the new way it works... for now.

This sounds amazing for my low-poly workflow, which uses a palette indexing for coloring faces (via a UV map). Sometimes, you want to be able to add surface detail (such as a decal), and that's often done with the knife tool on the surface of the mesh. Now, I can design the detail separate from the object and then apply it this way!

If this method isn't working for and your receiving an error like I was.

First select the object to be cut.
Switch to edit mode
Select an object from outliner (CTRL+LMB) to use for projection
Mesh -> Knife Project

The introduction of knife project into Blender had been a milestone in its evolution.
Ok, before that you had snap to surface method but it was a longer process.

There is so much to learn in 3d graphics and people like you are sharing valuable intel. Thanks mate!

Super helpful! And may I say how much I appreciate the fact that your videos are right to the point and no nonsense :)

Thank you for your videos. They are really amazing.
I was stuck with this for a while, but eventually made it work in Blender 3.0:
- put cutter and the object in separate collections ( perhaps this isn't exactly necessary, but in helped me )
- select the object and go into edit mode, then ensure that all of the object is highlighted as selected ( by default it is red),
- then Ctrl-click on the cutter3 ( should be highlighted green ),
- mesh -> Knife project. Done.

Once again, thank you for the work you do.

You just made my life so much easier. This is a phenomenal tool for shaping geometry.

Just jumped to 2.93.5 and thought I was going insane!

Cheers for the updated method!

this is actually so sick, I was wondering if there was something like this in blender just yesterday

[TR-wcis]

Thanks so much for this. I needed this a few weeks ago for a model and wasted a lot of time trying to figure it out. And of course nothing in Blender indicated that the workflow has changed...

[HiememMeow]

Wow this is actually insane :o your contents are all gold please keep up!! 👍👍💕

[cloudpotato]

I have been stucked in my project and finally found the solution! Thank you!

[NerylaLouvel]

Sir, you have saved my life. I can't wait for it to be tomorrow and continue working! Thank you!!!

[lucasdemeritt]

Thank you for always being there when I need to figure something out for the millionth time!

I had been saw so many video learning how to use this tool for build my work, and your video really helpful than the other youtuber, simple and clear, thank you.

[santiagostortirasio]

Muchas gracias, no me había enterado del cambio y me sentía un completo inútil !

[kirshak]

Each new video is an instant like from me, because I already know it's going to be an amazing knowledge that will be shared with us.

Thank you so much

[Cyber_Kriss]

Makes much more sense now than the previous way to do it.

[astrobatz]

This is awesome, you just saved me a lot of time, thanks

Wow! I'm new, but still surprised that I haven't heard of this before.
