Hello, thank you for your answer !
Yeah, I was a bit vague with my questions, sorry for that.
1- Ah, that's good to know !
2- OK, I will do the same, that's not a big issue.
3- I have to double check this one, didn't have a chance to try again since last time. I will update this later.
4- By a preview, I meant some way to show to the client/node PC, the rendered frame.
That's just my friends that are curious to see the image that their PC is rendering.
I linked a screenshot with what SheepIt does as an example.
(It's not a problem of course, just a feature request or curiosity).
Well, thanks again for the answers. Didn't have much time to test this with my friends lately, so that's good to know !
