Web9. jan 2024 · HLSL and GLSL have a function called refract which take the incident vector, the surface normal vector, and that ration of refractive indices, and return the refracted ray. When you do a raytrace down the refracted ray, you will have the same problem as when tracing the reflected ray, that you may hit the same surface you just hit again ... WebIn your update, you still set the velocity every frame in the transform.up direction. You need to rotate your bullet to the reflected rotation, instead of setting the velocity directly to the …
