Making a sphere brush

[mintoyatsu]

I need a func_physbox in a sphere shape, but the sphere primitive always results in invalid solids and slowly corrupts each time I save the VMF. I tried other shapes like cubes, cylinders, etc. and they just aren't the same. How do I make an actual sphere shaped brush for physics simulation?

Is there a reason this needs to be a func_physbox and not a physics prop? Brushwork is not really designed to handle perfect spheres.

If you're looking to make a ball, I'd advise trying prop_physics(_multiplayer or _override) with one of TF2's various ball models.

Try a prop_sphere (it exists!)

Unfortunately the size of the prop_sphere can't be changed, and it ignores "Start Asleep" flags. I also tried to use a ball prop with a collision model but it didn't work like func_physboxes do when stuck inside another brush. (for reasons)

I ended up using this tutorial on the wiki to create an approximate brush sphere shape that is a valid solid. https://developer.valvesoftware.com/wiki/Complex_Brush_Creation

What do you mean by this?

I have a sleeping func_physbox lodged inside a thin blockbullets brush. When the player shoots it, it goes through the brush out the direction the player was shooting at. With a model, it would always escape out of one side of the blockbullets brush and not the other, regardless of where you shot it from.

Are you trying to make a forcefield or something?

It's so the teams can't shoot eachother, only the physbox.

You can just use the physbox and set it to disablemotion.
