Hi!
Since I'm still just beginning to learn, it's a little difficult to know the capabilities and limitations of the engine.
I would like to know if there is a way to modify a geometry in real time. Not like an animated model, but like making a hole on the ground, for example. I'm thinking boolean composition or something.

It is possible if you use map entities or models and do vertex manipulation.

You can't do it on normal level blocks, but you can with models.

Thank you for the response

Not sure how to do that yet, but it's great to know such flexibility is possible.

I've been reading the manual trying to learn more about this. I think the vertex manipulation is limited to moving vertex, right? I was more interested in editing mesh.

I understand we have access to directx functions (or something), maybe this is the way to go?

look up vec_for_mesh

Thanks for the tip! But I think that won't do the trick.

This is great to simulate a lot of things, though..

If I could delete a single face of an entity I can simulate digging holes from there! delete face -> fill the gap with *this model* (to pretend it's a hole)

But I don't have anything specific in mind! This is just me playing around
