So far all the pictures posted have been on my 2 home pc’s that are many years old now. I have been limited to 14,000 x 8,100 pixels in size and about half of the “effects” that get applied to the renders. These still took at least 10 hours, if not a few days.
Luckily I got some limited access to a server with 8 CPU’s and more memory and HDD space I could use. I was now able to render images at 28,800 x 16,200 resolutions. Still less than a quarter the size I’m hoping for. But I was also able to use all the effects during the renders and they look so much better.
Below is an example of the difference the finial renders look compared to the older ones. The older one is on the left and the new higher quality render is on the right.
