Title: Will 1.7 improve memory usage?
Post by: chris_723 on 2017-10-10, 14:39:21
Hi,

Could anyone tell me if version 1.7 will improve memory usage?

My PC (just other two and bit years old now) has the below key stats:

32GB Dual Channel DDR3 1600MHz - 4 DIMMs
4th Generation Intel Core i7-4790 processor (8M Cache, up to 4.0 GHz)
AMD Radeon(TM) HD R9 270 2GB GDDR5

…and like many others, when rendering a not overally complicated scene (interior or exterior) over 3507x2480 it takes around 6/7 hours to do just two pass’s (over night) before I cancel it.

Looking at upgrading or buying a new 64gb machine to combat this is quite a costly process, and having never really had any unmanageable major memory issues with Vray, I wonder if this is the only answer?

I’ve been through my scene / scenes and optimised them as much as possible …following others advice on this forum (which is excellent) …but can now only conclude that either future versions want to make this more manageable or I need to spend a lot of money on a new machine to just be able to use Corona at a commercial level.

Any thoughts?

Thanks
Chris

I second this - Corona seems to eat RAM.

I've thrown huge scenes at VRay with no issues at all - hundreds/thousands of proxies, 8k textures, 3d displacement, and rendered them fine.

Add textures over 4k, displacement and a few forest packs with Corona and it just grinds to a halt.

Hoping this new Chaos Group acquisition will solve some of this though

Its a bit of a turning point …love working with Corona, but is it new PC love …but then maybe its time to upgrade anyway

Memory optimization is sheduled for 1.8 on Corona roadmap: https://trello.com/b/EfPE4kPx/corona-road-map-3ds-max Don't know how extensive it will be, though.

It's fine if you're only upgrading 1 PC - but if you have a network of them .....

To upgrade my PC alone it will cost £600 for 64GB RAM, purely because my current setup uses all the memory slots for 32gb.

I'd rather have better RAM usage than a new Frame Buffer skin.  Rather than add new stuff that isn't really needed, concentrate on the stuff that's desperately needed imo.  I'd rather it worked slick than looked slick.

You can try the standalone version. It's able to save 30% of RAM
But, Standalone doesn't support plug-in, some procedural maps.

it actually saves up to 70%, so the entire usage of standalone is 30% of the 3dsmax original

This is quite big issue, I tried the standalone on few scenes, at each one the exporter gave me hundreds of errors. I couldn't believe where everywhere are some native nodes embedded.

I wonder if the open-sourced ILM 'Material-X' could be solution. It's definitely the future of shading network transfer.
