ohh , you are talking about Iray. Haven't used it yet.

Exactly right!

And I have this FT ticket opened for almost a year now. And it's being disregarded. https://www.reallusion.com/FeedBackTracker/Issue/Please-optimise-digital-shaders-texture-and-embed-it-by-default
Embedding might be argued but the texture optimization is a must...

yes,  and if you haven't installed iray yet,  don't, it affects the performance of iclone and cc3 which was already showing serious degradation in performance from everything @4u2ges  pointed out.

Bassline303, it is not only about Iray.

Here is a simple test.
3 moderately clothed PBR characters take 1.7 GB of my GPU RAM



And now 3 almost naked CC3+ characters take 3.3 GB



Both projects opened fresh.

I understand DH shader and all. But not tiwce as much...

I don't have major problems, so I will stay out of the discussion. I do some optimization when exporting to iClone; so not 4k textures for everything.

@animagic,   whats your optimization work flow ?   usually when I go from cc3 to iclone ..i just "Send to iclone"   I really don't need all the 4k layers  for renders i like ...my biggest issue with many recent updates is all the time I'm spending undoing stuff I don't need ....I spend especially a ton of time removing all this new shiny 4k stuff - quality art is still subjective and not a standard.  we need a basic starting point that isn't so resource hungry.

some people need that extra detail,  i don't and only use sparingly when necessary,  not by default.

If you decrease the texture sizes in CC3.3 , you can save GPU Ram, also for Iray.

@Bassline303   valid point,  I'll mess around with those settings and see if i can find any imrpovement - thanks.
sucks that it's global tho,  as I said, sometimes it's useful on one item.   I've learned that the less you use something the more prominent and valuable it becomes ...so an option to keep everything lower rez values while keeping 1 item high res value is preferred for artistic purpose.

Also try Texture compression for Iray , I didn't activate it.

Tried new all time lowest settings as apparently I had already tweaked the panel once a while back -  still out of memory,

Now I'm testing a theory,  -  simply restarting the program and trying a render again.   If it doesn't give me the out of memory error,  then it reinforces my original claim,  the programs themselves need to be optimized for handling memory better in addition to not overtaking our ram with unreasonably  high default settings that won't be seen on an mp4 streaming from youtube on a smartphone.
Simply starting iclone now takes unreasonably long,  iclone and cc3 desperately need to be optimized to handle memory better. 

and just as I expected,  rebooting the program got rid of the low memory error,  it should have given me the same error consistently if it was my computer.   Iclone and cc3 need to be optimized,  and 2 other people with quality pcs are experiencing the same thing.
