[Max] Daily Builds / Re: Daily builds version 3

Sorry, my mistake, that example was with bumpmap enabled. This is with bump disabled, but there is no difference. Maybe I am using sharp enough diffuse texture.

Nekrobul: In my example I was not using any bump map or normal map or reflection map on floor(simple polygon), just diffuse, so it must depend also on something else.

15.aug. build
inside red rectangles is nvidia denoiser, outside is corona denoiser. Both amount 1.0.
1min. rendering, 3pass, GI/AA 4, LSM 1.0, MSI 4.0, adaptivity off, UHD cache
In this example nvidia is better(texture sharpness, env., curtain rod), except reflective surfaces and some parts of tiny geometry like kitchen doors, which are better in corona denoiser. So definitely interesting :)

From your render stats I see, that your scene has 52M unique polygons. That starts to be a lot. If you can optimize some objects which have lots of polygons, do it (reduce polygons on plants stems, flowers, maybe leaves...also rounded objects ). It helps you overall increase samples/s and hit that 50min. render time.

Adaptivity is sadly still unfinished feature from corona 1.4, so if you want to know what really caused 8x bigger render times you need to know which material is fastes to render and which slowest to render. Sampling focus render pass just tell you, how smart or how dumb adaptivity is.

PastaJackal: try disable adaptivity, maybe you will hit target noise level with less render time. Also If you decide to optimize materials, start with material which cover biggest area in your scene ( pink floor ). Please post here sampling focus render element, it is possible, that adaptivity is spending most time on material which is hardes to render ( lowest samples/s ) thats why you see so big render time difference ...maybe I am wrong, we will see.

Sampling focus just tells you where is adaptivity concentrating more or less, it does not tell you how hard is rendering some material for corona.

Just move small region render during rendering to determine which scene part has lowest samples/s.

3dsmax utilize only one core during work in viewport, so CPU will be allways bottleneck. Maximum turbo core frequency is important and your xeons have it 3.6GHz. It is not bad, but when you look at 4 or 6 core intel CPUs on market, they have turbo core frekv. 4.3 - 4.7GHz, which is better for fps.
Anyway, if you set percentage of pointcloud on all corona proxy objects from default 15% to only 1%, you will see another significant improvement in fps. The down side is, that proxy objects does not look attractive in viewport :))

You did it very well ;)

First check if gpu usage during work in viewport is 100% and gpu frequency is at maximum. You can use gpuz utility. Many time is CPU bottleneck...it depends also if your models modifier stack is collapsed or not, if you are using proxies in viewport or full mesh models. Also check if all objects have backface culling disabled in obj. properties.
If you have all nitrous engine features on with scene lights and transparency ON, then go and buy 1070/1080. But I think 1060 will be also good option. How big are your scenes (interiors/exteriors)? What FPS is good for you?

Here is good table with all nvidia GPUs https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units
You can compare graphics cards according single precision column.

Hi,

if I convert all Bitmaps to CoronaBitmaps using corona converter and press render button, max immediately crash. I tested on two of my scenes.
Scenario 2: If I convert bitmap to cBitmap, then convert it back (cBitmap to Bitmap) and hit render button...no crash, no issue.

I am sending scene via private uploader (1527232598_coronaBitmapCrash.rar).

Max 2018.4, corona1.7.4, corona converter 1.42

Can you confirm that when it slows down, the 3dsmax.exe process is still showing 99 or 100% cpu usage in process tab?

Great job, it had to be a huge amount of work put all things together without glitches.

Some rendering stats? samples/s, rays/sampe, num total passes,... Check albedo color on walls and also check materials of objects which cover the most of the area on render...if they are not too complex. I sometimes forget to use portal material in windows :D, but probably it is not your case :) .
BTW. nice renders on your web page, maybe 24h to clean up is normal in that top view....did you try another camera angle in that room at that resolution?

[Max] I need help! / Re: Resolution dpi for screen animation
« on: 2018-05-18, 10:37:10 »
It doesnt matter what DPI, more important is resolution. If the screen is FullHD, then set your animation resolution to 1920x1080 pixels. If it is 4k display...it depends from which distance will be people watching on it...probably 1920x1080 will be great and sufficient too
