I know there are some posts about farms, but they're all over the place and many are very old.
I have some architectural type animations I need to do. Static room and simple, slow camera moves. It's just too much for my old iMac Pro. A 10 second move can easily be 24 hours with moderate number of passes and denoising. There is a long list of farm services on Corona's web site. It's a little daunting. So far, Rebus is the only site that I can input my exact CPU. The others I have to guess a comparable chip and fingers crossed.
For Corona peeps that have used farms, what is your top five companies I should look at for price/performance? I assume I'll have to be careful with shared textures and the Corona Bitmap problem.
The other question is, I have been using the daily builds, but not using any specific feature of v10. In the past, I have rendered newer Corona version on nodes with a lesser version of Corona without problem. I'm sure I could go back to v9 and save again. Thanks for any advice.
