Need assistance with mirror reflection rendering – Cocos Creator


Hello all, I wish to create water reflection in my sport. I learn few tutorials and understood I want to make use of second mirrored digital camera and render texture than I’ll render in aircraft, however I get hassle with the improper dimension of render texture, or with aircraft I don’t know precisely.
Here’s what I achieved:
Right here is my world with 2 cameras (first important, second mirror reflaction)

within the backside is blue aircraft what I’m utilizing for render texture, now in play mode I’ll disable haxagons and you’ll see my rendered texture in aircraft:

As you see, the rendered texture, smaller than 3D hexagons.
My render texture has 1024×1024 dimension, and aircraft scale is (1, 1, 1), so I don’t know what I’m doing improper.

One factor I seen that my important digital camera has isWindowSize property true, when my reflection digital camera doesn’t have this one, as a result of it has render texture. I attempted to vary the scale of reflection digital camera and render texture to match important’s digital camera width and peak within the code, however the dimension nonetheless was improper.


please present each digital camera settings, the digital camera fov and projection should even be aligned

Thanks for reply, I’m utilizing this code in lateUpdate, so they need to be the identical:

I feel the issue is my important digital camera isWindowsSized, when my reflation digital camera isn’t:

Reflection digital camera misplaced its isWindowsSize once I connect targetTexture to it.
Additionally, it may very well be some downside with aircraft the place I render the feel. Nevertheless it has scale(1, 1, 1)
