Hi guys,

I have a problem in Corona 1.6 and 1.61 where on a certain scene if i do a render and i haven't cleared the frame buffers previous render, the new render blends 50% with the old.  I can do x number of passes and it is still 50% there.

Any ideas?

Cheers

Iain

hi,
do you have denoising with amount set to cca. 0.5 enabled?

Hi Ondra,

I've looked a little more into the problem and it is only visible in th Lightmix pass with denoising enabled. 

I render the scene and allow for 5 passes, then hit stop and allow it to denoise.  I then change camera and hit render again without clearing frame buffer and it mixes 50% (or so) with the previous render (5 passes) until the point when i hit stop and it denoises.  After denoising has finished only the new render is visible.  However if i hit cancel instead of stop on the 2nd render i'm left with a mix of both renders.

The denoising amount seems to control the percentage that it is mixing too.

Thanks

ok, and the beauty is fine during this? Or the same problem happens there as well?

Hi Ondra - The beauty pass is unaffected, only the lightmix pass.

Maru - Yes i believe those post are related to the same problem.

Thanks
