Interesting, why you set |
|
I started using the USER cameras and then I saw that I didn't need the default camera. Also, I think that when rendering to texture, the sprite was showing on the default camera on screen. Maybe I could add an extra USER camera for rendering to texture but this was more straightforward to me. Furthermore, I'm not sure about this, but I see that some objects do some computation if there is a default camera on the "visit" or "render" functions when enter this Thanks! |
Oh, you mean why I use this line? |
