    I don't use a laptop, so I don't have a touchpad. But in general, rendering can pretty much freeze up your computer's responsiveness, even if rendering in the GPU. Sometimes I can't move the cursor with the mouse, or it moves so slowly and jerkily it is unusable. I have only one GPU and it must run my rendering and my screen.

    Thanks for the response. Do you often render dark moody images? I typically render larger than 2000x1500. I usually leave convergence at 95% and usually get satisfactory, noise free images.

    Have you done any photography?  I wonder if we just have different preferences.

    No, I don't often render dark moody images. And most renders don't take tens of thousands of samples to complete. I wish I could remember a specific example where 15,000 wasn't enough and I increased it. I know I did that just recently, but I can't remember which scene it was. It was probably a spot render on a troublesome section. I've been doing some product testing for a PA and rendering a way more than the normal number of scenes in the last couple weeks. It may have been one of those. Sorry for being so vague. frownI see no down side (for me) in setting the number of samples to a very high number. I don't ever want a final render to stop because it reaches an arbitrary number of iterations. If I want to be sure it doesn't run for hours while I sleep, or something, I will limit it on time and still use a very large number of samples.

    I do also sometimes set number of samples very low, like 25, if I am in Iray preview mode while experimenting with different materials or shaders. That it gives me a pretty good idea of what the material or shader looks like quickly and stops rendering until I make another change.

    Yes, I do a lot of photography. Why do you ask? Are you thinking of low shutter speed/high ISO noise?

    @barbult  "Yes, I do a lot of photography. Why do you ask? Are you thinking of low shutter speed/high ISO noise?"

    You have a good point about not stopping a render simply because arbitrary point was reached. I also think I interpreted your 15000 sample remark to mean you habitually let the render go for 15000 samples.

    I asked about photography because I have observed that compliants about needing higher convergence / longer rendering / more iterations often stem from poor lighting. Poor lighting in turn often stems from not really understanding how real world lighting interacts with a camera. I see that that is not the case for you.

    Anyone that has done much photography gains a practical understanding of scene lighting.

    Too many people seem to expect Studio to render as if it were their eyes rather than a camera (thus not enough light / more noise / too dark and on).

    I cannot render in Iray at all since this update (CPU rendering, as an nvidia card is not yet in the budget) The render window just starts with the "close" option. The log shows:

    I uninstalled and re-installed Daz, now it seem to be working

    That's great! I have no idea what those error messages mean.

    Does anyone know how to fix this?

    You can use the Windows Snipping tool to take a screenshot, rather than taking a photo of the physical screen.

    By the look of it you have closed your Viewport - you can reopen it from Window>Panes(Tabs)>Viewport, then drag by the top edge to the top of the empty space until you see a line of orange, then drop to dock it. You can also just reload your layout, Window>Workspace>Select layout, but that will reset everything.

    Will that include my entire library?
