100% transparent polygons - collisions?
Blitz3D Forums/Blitz3D Beginners Area/100% transparent polygons - collisions?
| ||
| Well, in my project I'm using cylinders that are 100% transparent (alpha). I'm also using polygon collisions... Could it be a possible speed issue? Polygons are not rendered on a screen, but computer still has to check collisions. Or is it perfectly fine? |

| You'll get more speed, if your not rendering them, and only using them for collision purposes. |

| I often use 100% alpha transparent meshes for collision purposes. You probably should try to use simple shapes and low numbers of facettes / sides etc. If collision is not required, you may hide the mesh instead. |
