DEMO Godot shader: Cross section using raymarching V1

I thought I could simplify this shader into a single pass, but it requires unshaded mode to work (as you can see the model has no shadows). So I need to use two passes necessarily. I'll control both shaders with gdscript and add several additional parameters in the next version

Nice work !

Very cool! 👍

Hi! your cross-section method looks very interesting, I was wondering if it was possible to insert multiple section planes, in my case I would need 4 of them, one on each side of the model, so to reduce an object into a square more or less, would it be compatible for such an application? Another question, can a plane cut multiple objects at once? thank you!

Currently it doesn't support multiple planes, I don't know how difficult it is to implement it or if it is possible. About if the plane can cut several objects, yes because the shader takes the plane reference from outside, so if you apply the same shader to several objects they can share the same cutting plane. Also keep in mind that this shader draws the result of raymarching on the inverse face (FRONT_FACING) so if your model has parts of the mesh overlapping it will not work.

​@@pixezy8962 I kind of imagined that it was complicated, and unfortunately the multiple objects overlap as well, thank you so much for the superfast answer!
