Destruction Test No Water 

Yeah, each material can have its own set of physics parameters (will eventually load from text file or database that can easily be updated by user). I think I figured out the problem. I'm using the same values for compressive and tensile strength, which is ok for jello. But for bricks/blocks of stone, the blocks need to stop affecting each other with shear and tensile forces once they separate. Will show updated material in future video once I get the material database and in game material editor set up.

I can't wait for this, I love it! I think that part at the end when most of the building is destroyed is really cool, like it's some temple dragon or something. Awesome

@@GrantKotI tried the demo recently, and this still seems to occur - the buildings are soft like jello. Any plans to address this ?

@@nolram I am definitely planning on making some more improvements to this. Tbh, I am not sure I will be able to make it perfect with purely the MPM grid. Might need a different system to get it behaving realistically but that could be pretty expensive for the CPU. Also I feel like with the extremely configurable material visual properties maybe I focus on alien or outdoor worlds? It works well for bendy trees/bamboo and stuff. I also have the static blocks system which is super cheap on the CPU, maybe I could do some fake destruction on that where it removes the block and spawns some particles into the scene.

@@GrantKot You could try and enhance the static block system maybe so it can detect disconnected chunks and make those independent bodies ? Also, if you can just slightly harden this soft destruction, you could potentially use it for wood, which is usually quite difficult to model !

Sorry if this doesn’t make any sense I don’t have any Voxel coding experience

Hi, don't worry, makes perfect sense and your suggestions/feedback are always welcome. I am working on setting up a database for the game so users can easily edit or create new materials, and a in-game material editor where you can tweak the material properties and see in real-time how the behavior changes (kind of like the iPhone app). And I'll make a video for that demoing the different properties.

I've released some demos in the past, this is the most recent one: kotsoft.itch.io/mpm-tech-demo But they don't get a lot of downloads, and I think it's kind of a hassle for people to install via itch. I also worry that by putting unpolished stuff up it might give negative impressions of this game that is still very much a work in progress. So I'm working on getting something more polished that I can put up on Steam in about a month or so.

Yes, I am working out a volumetric lighting system and trying to support transparent voxels that can reflect, refract, and scatter light.

Yeah I am aware of a game called teardown. Maybe that’s what you’re referring to? This is somewhat influenced by it but my game will place a lot more emphasis on water physics.

Yeah it's TearDown
