[Max] Bug Reporting / Render selected blurs background

« on: 2019-12-14, 14:20:50 »

I was need to render several variations of doors, and used render selected option with unchecked Clear VFB between render, it appear what makes blurred background.
Attached image from the sixth renderings, i marked selected object.

Also sometimes NAN errors appear, i am sure it because of render selected not the scene setup because single full rendering never gives this error.

[Max] Bug Reporting / ShadowCatcher reflection Bug

« on: 2019-04-06, 10:22:35 »

Original topic here
https://forum.corona-renderer.com/index.php?topic=24220.0

if you open the scene it has black color in environment and one light source, if you lower glossiness in shadowcatcher, the reflection of object disappear in alpha channel, and it will appear again if you change color in environment or turn off light source.

another bug if you set intensity to light source 0 it start to reflects in alpha

[Max] General Discussion / Monitors and pixels

« on: 2018-12-28, 13:24:35 »

Hi
I want to discuss with you about new monitors. I bought Philips 436M6VBPAB it is big and cool, have hdr etc.
But i start notice some issues with pixels. As you know many new monitors making new matrix with TV pixels BGR, for smooth fonts issue in system it can be fixed with changing AA fonts to BGR in cleartype settings.
But for example in 3ds max in preview of small noise map monitors drawing like color noise. Also i see at old render images jagged edges what i did't see at old monitor, there was no jagged edges as corona AA makes it smooth.
So maybe for 3d graphics should be new AA algorithm for BGR pixels like for fonts?
