I’m using the code below to render my output to png files, but when I use fog I get a semi transparent image, where it looks like the depth channel is being used for alpha…
any ideas around this?
actually - just to clarify things
the above code simply outputs the image without any fog effect - but the scene is normal
it’s when I tried to render the scene into a separate framebuffer, then output that, that I get the transparency problem.
I took a look at the fog filter and its not really possible to get a transparent result unless your fog color is transparent as well. Make sure it has 1.0 for alpha.
Make sure it has 1.0 for alpha.
that was indeed the problem - though tricky to spot, as the screen output looks unaffected by fog alpha..
