Can You Render a Scene Twice?

kocammy

I realize this may be a completely dumb question, but can you render a scene twice without starting over comletely?  For instance if my render finishes and I'm not happy with it do I have to start a new render or can I basically pick up where the first render ended?

Thanks

Many find it helpful to render in an image series so that if you find the render not working as you want it, you can easily stop and then pick up the render from that frame. This is for animation of course. I don't know of any way of stopping a still frame render mid-render and then picking up where you left off.

Which application? 

If DAZ Studio: I've never done it, but vaguely recall somebody mentioning a way to get DAZ Studio to do a spot render to a new window lined up in such a way that it lines up perfectly with the full render, so you you could then use Photoshop (or whatever) to overlay the spot render on top of the previous full render, you might want to research that spot render.

If Bryce: Just left-click and drag a rectangle anywhere in the rendered view to spot render over the top of that portion without affecting the rest, then resave your image.

To do a spot render to a new window select the spot render tool (circled) and then in the tool tab select Render to new window

If you render in Iray, and it's things like Tonemapping, or convergence, etc, you can change the values, and then resume the render.

As for changing the position of things, or colors, then you will have to start a new render. The same goes for 3Delight renders, which can't be resumed.
