Search for a true 4 axis Cam

Hi 

I saw a video here : www.youtube.com/shorts/e60EBb8NXKA
It seems to have a 4 axis machine doing undercuts and true statue carving.
I have extended my LCNC 2.9 version recently with a rotary axis, so now I have X Y Z and A axis. Rotary is parallel to Y.

I am looking for some CAm software like the one used in the video to carve extended arms and horns as done in this video.

Which CAM am I looking at ? The comment in the short video says  powermill, alphacam, UG.

I tried desproto 7.1 and was able to create their venus model perfectly. But when I put a more complex design with statue having extended arms, the CAM seemd to not be able to do it or there was complex setup for the same.

Can someone suggest which CAM has builtin PP and support for linuxcnc for such carvings ?

Cheers
