Can you help with meshes and everything that follows?

Question

Unity

Need help with meshes and all that comes with making the car deform from the explosion. In YouTube, Google, in bing, in Yandex, I looked everywhere for information on how to do this, but all the guides were either posted several years ago or made in a prehistoric version of the unit. the explosion itself, the mine, everything seems to be there, you just need to make sure that the car can crumple from the blast wave of the explosion, and from subsequent collisions with nearby objects. I will ask all those who will say "Study yourself, you need to" and similar expressions to go through the forest. I searched for info, I did not find a suitable info. Who will help and explain how I can make parts of the car rumple? How to add polygons to make deformation possible? Discord Dark Hacker#3079

Answer 1

in general, this is quite difficult to do, either buy / download an asset for deformation, or use model substitution.
I can explain: to increase the polygons, you need to throw the model into a blender and apply the subdivision surface modifier, then you need to deform the model, for which you need an explosion radius, then we determine which models fell under the radius, then we take the mesh of this object and check whether each point fell into the radius explosion (at your discretion, either select all that come across, or only the closest ones in the path of the beam from the explosion), then you need to move them away from the explosion and, ideally, you need to calculate the physical viscosity of the material (so that not just a piece of the mesh moves, but it deforms), do deformation calculation, apply the mesh, just change the mesh, not the one that is in the meshrenderer, but copy it, change and paste the copy, otherwise you will change the original one. something like that, good luck, I do not advise you to do this if you have no experience in programming,
