Godot Version 4.2 Question So I dont how to search it up because all I ever see is just 2D health bars in 3D space which is not what I am looking for. But in my game I want to have 3D model of a container and everytime the player gains or loses health the container fills up or drains the “water”/“…

There you go. Your basic shaders are as follows. Note that a lot more finesse can be added but this does the main trick. Pass 1: shader_type spatial; uniform float fill = 0.0; varying float vertex_world_y; void vertex() { vertex_world_y = (MODEL_MATRIX * vec4(VERTEX, 1.0)).y - NODE_POSITION_WOR…

oh this is a start but not sure how to translate that to what I need, I guess Ill fiddle around with it and see what I can do

yeah this its just dont know how to get here

Run a 3 pass shader on your container mesh. Pass 1 (liquid side): discard all pixels whose y coordinate is above the fill value supplied via an uniform. Pass 2 (liquid top): same as pass 1 but cull the front faces and set the normal to always point upwards. Pass 3 (glass): Displace vertices along…

oh wow I was about to say that I wasn’t a shader person so I wouldnt really know how to achieve that but now that I see the video I see that this is really cool and surprisingly a lot simpler than I thought.

You can’t really do it without shaders if the form is anything but a regular cylinder, which can simply be vertically scaled (as in @tomcat ’s example).

So I have some question about this because I am currently fiddling around with this. But how do you change the colour or add texture? Because in your demonstration video its purple but for me I cant seem to change it from the basic white colour.
