Get a Cube's face top left corner

Chadribleu

Hi! I'm new to Godot and game dev in general, and I'm making a Skin Editor for the game Minecraft as a first project.
I want to add a preview when the mouse is over a cell in the grid (See the picture below for more explanation).

My raycaster can return the position in Pixel on the model's texture. Each parts of the model are collider if it can helps.
I would like to get the top corner of the hovered face, so I can use that to determine where to draw the brush preview element.

Thank you in advance!

Chadribleu How do you want to draw it? As a proper 3D face with a texture in 3D space or (if the user can only rotate the viewport in 90° angles) with the build-in Godot drawing functions?

Chadribleu you could get collider transform3d aabb bounding box extents https://docs.godotengine.org/en/stable/classes/class_aabb.html#class-aabb with this you could get the outer points of the box and then use draw() function to draw a line between them or maybe do some shader magic ..

Toxe Hi! I would like to draw it as a proper 3D element. The user can rotate all around the model, so it's probably the best way to do it I guess!

kuligs2 I'm gonna check for the AABB thing! Thank you for your response
