Files not saving

[simonfarussell]

Hi,

Corona renders in the viewport but files do not save. I've removed plugins, installed the latest build. Trouble shot the scene and nothing. Any ideas? (Also I've filed a report but not answer).

Best,
Simon

It seems that if Pass Limit, Time Limit and Noise Level Limit are all on zero no frame is saved. If I change it a frame is saved.
Am I missing something or is this a bug?

No, you have to tell corona how long it should render the frame. Otherwise it won´t stop. You do that either through passes or through time limit. Or noise level. I normally render till noise level hits 2%. Or 4-5% + denoising.

Ah thanks. It's different from the behavior of the build in progressive physical render for example. That's what I was expecting. A bit strange perhaps that the default options render infinitely and don't save but hey

The defaults are set because there's no way to know when a user would want the rendering to stop - by passes, time or noise, and whichever of those 3 are chosen, what values would be needed by that scene. So the default is "render indefinitely until the user decides it looks good enough and they press Stop" (at which point, if you press Stop rather than Cancel, it should save, I believe).

Hey,

Yeah I get the logic. It's just a different convention. And I'm a noob.

Thanks

You can test the scene by rendering one frame to know how long you have to render it.
Or you set the noise limit. I read somewhere that good values are 2% without denoising or 5% with denoising. Just to get a feeling for it …
