I would like to change the number of threads used during a render. Pause the render, then change the threads use to one, or back to two. (I have a P4 HT) Is this possible?
i think that may cause errors.
seems like i once accidentally changed render setting when forgot i had render going, and i immediately started getting errors.
I try the same thing again later, to see if it really happends.
Can't you simply disable and then re-enable threads (CPU cores) that tgd.exe is using by entering the task manager in Windows?
You can set the affinity of the cores used. This makes the program run on specific cores. I've done this in Blender, which did not like it. It also causes system instability.
Hi,
Changing any setting during rendering, paused or not, is asking for trouble really.

Well, that's ok. I was hoping it would work. I change the programs priority using task manager all the time. It would be nice to restrict the number of threads when I want to do something else when all cores are being used.
If only we had a "save render" like ancient Bryce had..... :)
If you want to restrict the amount of CPU usage during rendering, just use the Affinity settings in your Task Manager. I don't think it would actually work using the settings in TG2 during rendering, and even if it did it's asking for trouble, like Jo said.

I have not had any problems changing the programs priority. But the ability to save the render buffers, stop the render, and then continue the render would be very helpful.
If I have something really time-consuming to render and I have a super-urge do play a game for some time or do some heavy processing in other software I simply pause the rendering and as I have 8GB of RAM - TG2 leaves enough memory for other applications.
But if I really need to turn off my rig, I simply pause the render (not really required, just to be sure everything is ok) and hibernate Windows. I've been doing this for a long time now and I've never had a single problem with that. So that's a bit of a workaround if there's no built-in resume in Terragen.
I have turned of my computer maybe nine times in five years. I like to keep it busy rendering.
