If I render a shot at any frame of the simulation mental ray works but if I want to render the entire simulation in batch mode the result is always the same first frame. KDNS. Board index; All times are UTC. Physics of firing a bullet straight down from an aircraft the bullet spin should make it drift one way or the other. Anyway, importantly the horizontal and vertical motion decouple and so do not influence each other. Initially I set up a world with the ODE physics engine, a block model with a contact sensor and another block model both floating in space. Unity and Havok Physics both interface with the DOTS framework, which means that although they serve different production needs, it is possible for a project to seamlessly transition from one solution to the other or use them both simultaneously for different use cases. I've been messing around with Bullet physics for a while, and I'm very impressed with it. Like the rest of the site, it is filled with scientific theories, knowledge, and information. Terminal velocity is the point at which the resistance due to air reaches the point to where it is equal to the weight of the object pulling it down. All it is, is a calculation in the trajectory which the game can do quite easily. I started using bullet physics and to my demise found out that when I open octane's viewport, it ignores the simulation tha If need be I can find the video and repost it of the Doc playing just yesterday, 4/9/18 and with a SUPPRESSED M4 and a 100m zero had to aim UNDER targets at 150+m! That's how bad the bullet "physics" are in this game if you can even call it "physics" at this point.
