Daily Builds 1.0 - 1.4

[romullus]

I just found that in some conditions VFB clamping may have significant impact on denoising. Is that normal?

[Ondra]

can you be more specific?

[romullus]

I have scene where setting VFB clamping to 0, 1 and 2 produce very different results in denoising. Specifically  at 0 and 2+ denoising works as expected and between those two values it almost don't work at all. Will provide some example images later.

[Ondra]

ok, provide the images, but using clamping 1 is from the "biased as fuck; anything can happen" domain :D

[romullus]

Heh, i use clamping at 1 for some time now - didn't notice anything starting with F letter... until today. I use this scene a lot recently and today noticed that just by changing white background to black (shadowcather) makes big difference in adaptivity and denoiser behaviour. Not sure if it's related to new daily (apr 05) or that i just didn't noticed it before. I'll probably try to record video to make things clearer, but it'll have to wait for tomorrow.

Hmm... are there any known issues with displacement atm? I can't get screen based size to work at all (even with 1px) - it's all blurry like hell. World space however seems to work.

[antanas]

Well, it seems to work alright or at least it does so in my case - this one  http://c2n.me/3wFH2xa - using corona bitmap with 0.1 bicubic filtering and this one http://c2n.me/3wFL7x8 just a regular 3ds max's bitmap with 0.02 summed area bluring\filtering with default 2pix displacement - both tested using 2016-04-05 daily build.

Here's two images, one rendered with VFB clamping at 0 and other with clamping at 1. Both adaptivity and denoising are enabled and at default settings. Yesterday i was able to achieve much more severe difference - it's all very dependant from exposure and camera angle. I guess, pixels that gets clamped are left without denoising?

Anyway, i turned VFB clamping off for now and everything seems fine.

[Ondra]

I can imagine the clamping screwing some statistics that are used for denoising... can you share a scene where the effect is severe and reproducible (on mantis)?

[romullus]

I've managed to create scene with pretty severe case of denoising failure. Created mantis report and uploaded scene. Hope this helps.

Added interactive and multiple render region drawing into Corona VFB. Shift draws a new rectangle

F*** YEAH !!!!

[guest_guest]

is any string option or tricks in config file to enable the bucket mode?

[Dom74]

with the latest release (2016.04.08) I have noticed a strange behavior of the VFB when switching from render/interactive render, the resize seems to be broken and the picture is offsetting to the bottom/right

afaik bucket mode looks like has completely removed.
in maxscript, it was

Code: [Select]

renderers.current.shading_renderEngine=0now 0 value in renderers.current.shading_renderEngine (bucket mode) is replaced with "simple path tracing" engine.

resizing VFB in IR mode works good in my scenes.

I can confirm this. And once this occurs it can't be cured by any means but complete max session restart.
