Hi Support!
Hope you are all well in these testing times🙏. I am stuck indoors and set myself a architectural project to wow my clients with. Unfortunately it's become too complex to render on my 3 Macs (only 16Gb per Mac). I can render them at 1280 x 720px but not at 1920 x 1080px. My Mac runs out of memory and pauses C4D. I have stripped back all apps so only finder and C4D are running. The scene is very complex with trees, plants house objects and a texture folder with 1.27GB (470 items).
What is my best option to get this to render. To reduce polygon count or amount of textures? Many Thanks, John 😎👍

If increasing the resolution causes your RAM to run out, it might be caused by too many render passes. Could you maybe reduce the number of the passes and try to render that? You could for example split the project into two versions before rendering, with each version having one half of the passes and then merge them afterwards in post.

Or render only half of the image at a time and stitch them together in PS... :)

Hi All,
I have downloaded a lot of free models with very high polygon count (especially the curtains!). Would it help if I reduced these objects and maybe reduce size of textures? I have never rendered a image half then stitch in PS. I like the sound of this approach, might work. How do I do this?🤔👍 Thanks for all your swift replies!

You can try this trick to render larger:

I wouldn't recommend that, because the stitching might be an issue, unless you somehow overlap the images.

I wouldn't bother with geometry, because there's not much you can gain, but reducing textures resolution, bit depth and channels where's that possible, can gain you tons of memory savings. Basically every texture, except for displacement maps should be 8 bit depth. Every greyscale texture should be saved as single channel image. As for resolution - check if there's assets that are very small in final render, but has fairly high res textures. By halving resolution, you will reduce its RAM requirement 4 times!

Hi All & HAPPY FRIDAY🥳!
Again, thank you for all your help. Think I will trawl through the textures and reduce sizes as there are SO many. It does work at 1270x720 so will do them this size for now. I am switching to PC next week. Getting a Gigabyte AERO 15" 4K UHD AMOLED Studio Laptop with 64GB of ram next month so it will be a good scene to test it with. Would you say it is a good laptop for Corona use or should I go for something different? John 👍😎
