[Max] Feature Requests / Ram Usage overview, maybe more information?

« on: 2023-03-21, 15:58:28 »

Hi corona developers, i want to raise a hand for a complete ram usage overview, right now i can use the Csv file that corona generates (maybe a bit easier to see, even before ram gets low ?? ) but that file just has texture ram usage, were can I see the geometry ram usage ?
Maybe a more robust file to see all the statistics ?

All the terrain has a corona layer material with displacement (composite displacement and masks)
The scene only has the terrain and the forest objects

Scenario were it works:
Displacement on, terrain isolated   OK
Displacement on, all the itoo forest objects Isolated  OK
Displacement on, all the itoo forest objects WITH a different surface terrain that the one with displacement   OK

Scenario NOT working:
Displacement on, terrain and forest objects visible  NOT working

« on: 2023-03-09, 14:12:38 »

Hi, just now i saw a great article about vray going Qt for the materials, So we know corona materials are Slow, but how much is SLOW.. well i timed at 2.47 seconds for the corona physicals material.
NOT on a fresh new max, but on the same file the autodesk physical mat is redrawn almost in a blink.
So here is the video

[Scatter] Feature Requests / Chaos scatter Renders Non renderable objects. / and a wish list for it

« on: 2023-02-22, 20:32:50 »

If i add a non renderable object , chaos scatter will render it. Just create a box, go to object properties and uncheck  Renderable, make a scatter with it and you will see.

*Another thing is that i want the ability to add dummy objects to a scatter, that way i can create interesting effects when using Itoo Forest (in forest i just add an object and disable it) +
*On other topic, it will be nice to be able to change all the objects Frequency at once. if you have 5 or 10 objects in your scatter you need to change it one by one..

« on: 2022-11-24, 15:18:27 »

HI, we are using corona 9, in the new frame buffer we cant enter values that start by 0.
Just values from 1 and up. If you use the spinner the values can be less than 1 .

Off-Topic / GPU-accelerated distributed rendering of massive scenes

« on: 2022-11-01, 23:59:16 »

Pretty much real REAL time here, i love corona, but also believe that gpu rendering is the future.

if you are not interested in the technical part, just jump to minute 21:50 to see the magic.

[Max] Resolved Bugs / Volume Materials and opacity light sources Produces wrong results

« on: 2022-07-22, 15:55:55 »

Hi, we have a problem with corona when using light sources (real lights or self illumination)
If you have a global volume material or a volume effect on the scene the opacity maps will have a halo effect visible on the diffuse channel and very visible on the alpha (i have tested cliping the maps in all ways) I have a small scene attached to  see the problem.

[Max] Feature Requests / Lower Memory Usage / Texture Compression

« on: 2022-04-11, 16:53:32 »

Hi, some time ago i read about the Cbitmap future ability to load the needed resolution of the texture for each scene (something like a tx texture?)
Were is corona with that ? or any other memory reduction capability  like texture compression ? Have you seen the texture compression with gpu decompression? Looks incredible!
Hope to have some news op this, One of my few complains of corona render is the high memory usage.
Thx all!!

« on: 2022-03-16, 15:36:14 »

Hi we have a scene were corona and max crashes if the render elements are active at a resolution of 3500px, the memory just hit 10gb of the 64 available
If the render elements are disabled the render starts and finish, if not the render wont even start and crash right away.
Already merged into a new scene, sued forensics and prune scene to clean it, but its a small scene..
