I wanted to test the Corona bitmap lower memory consumption on V6 and I found some interesting things that i like to share :
The test project consists of 969 bitmap files ranging from small to very high resolutions, on all kind of image formats.
3dsmax file with two fully furnished apartment floors
Here are the results
First time Opening the project
3dsmax Bitmap
Memory used on 3dsmax process 14.3 GB
First time rendering Memory Usage 32.9 GB
Scene parsing time 1:02
Geometry parsing time 0:02
UHD Time 0:11
Second render
Memory usage is the same
Scene parsing time 0:11
Geometry parsing time 0:02
Interactive after second render
Scene parsing time 0:11
Geometry parsing time 0:02
--------------------------------------
First time Opening the project
Corona Bitmap
Memory used on 3dsmax process 22.5 GB
First time rendering Memory Usage 27 GB
Scene parsing time 0:44
Geometry parsing time 0:02
UHD Time 0:09
Second render
Memory usage is the same
Scene parsing time 0:19
Geometry parsing time 0:02
Interactive after second render
Scene parsing time 0:22
Geometry parsing time 0:02
--------------------------------------------------------------------------
For the lazy ones that dont like to read that info :
Corona bitmap CAN lower the memory consumption on the RENDERING side, but will use more memory opening the max file
Corona Bitmap will be faster on the scene parsing the first time comparing to 3dsmax bitmap, BUT the second time 3dsmax bitmap will be faster.
So if you are having memory problems corona bitmap is a good option, but your starting times will be longer.
I can share the scene with the developers if they want to take a look.
All test were made on 3dsmax 2021.2 Win 10 Corona 6.1
