[Max] Bug Reporting / Re: Very slow geometry phase 10x slower than old pc

« Last post by TomG on Today at 12:46:20 »

News or findings will show up in a daily build as a "we hope this fixes...." ;) Or if something comes up where we'd appreciate a test "if you disable this in the BIOS..." or similar. So that is when it all becomes relevant for folks to test things - up until then while we are testing internally, there won't be any news.

Yup same scene, same textures etc. The Corona benchmarks between out two machines are shown. His is only supposed to be twice as fast and yet it seems to get four times the speed using VFB…

No RSM warnings either.

looks like you have everything you need here:
https://forum.corona-renderer.com/index.php?topic=40952.msg216985#msg216985

you are good to go with luts I posted a while ago.
edit: no need for string options or gamma operators in vfb.

in Corona Image Editor / VFB:

LUT: mP_Corona_AgX_A_matrix.cube  (this is color matrix from AgX ocio config simulated as lut for Corona and Corona only, it relies on how Corona handles luts, will not work as expected anywhere else - use ocio instead)
LUT(logarythmic): mP_Corona_AgX_B_log_AgX_kraken.cube (this take us to AgX Log (Kraken) - make all your colour correction, grading, look or whatever here)

here goes your custom look, lut most likely. create it on AgX Log (Kraken) image saved from CIE or frame buffer. in Fusion, Photoshop etc.

LUT: AgX_Default_Contrast.cube (attached below, this one would put your Kraken log nicely on a srgb display. edit: nicely but still missing the "look" so it is "bland" on purpose. this is cube version on the lut from original AgX ocio. 1D lut, just a contrast curve. you can obviously add this transform to your look for convenience)

and if you find AgX great - do not forget to say Thank You to Troy Sobotka: https://blenderartists.org/t/dealing-with-aces-agx-srgb/1480752/662

[C4D] I need help! / Translucency on Mult-Pass Masks

« Last post by wardy_mk on Today at 12:00:59 »

Hi. I have a quick query.
A lot of the things I do are retail concepts. A lot of these feature a clear acrylic case/tank/box to stop theft. I'm sure you know what I'm talking about.
Sometimes (more often than not) the client would like to see the display on a completely white page.
So, if I do this and set a muti-pass mask it'll do a solid block alpha channel of the whole unit. Whatever was behind the clear acrylic tank/case in the original render will be shown.
Is there a way of creating a more 'in depth' mask that captures the translucency of the material so I can overlay the visual on to any background?
See below for an image of the results I'm getting at the moment - branding and product blurred out because of NDA's etc...

A workaround I can do at the moment is put a white box right behind the boxes but it's not ideal!

almost never.

always the 3dsmax corona vfb with some editing in the tone mapping (but very simple, most of the time just AgX Lut), and most of the time directly saved to .jpg

Any news or findings from the dev team?

Hey Romullus, thanks for your reply.

I did check the UVW mapping of the wall object and it was set to RWS, although I since realised the plank bitmaps were not set to RWS. Once I did this and figured out the correct UV sizes it has started to look more as expected. Not quite perfect, but getting towards the end goal. As attached screen grab from VFB

Thanks again!

From that benchmark the Mac is almost 3x faster.

I assume you are rendering the same scene, do you get any RAM warnings on your machine?

Regarding the speed from VFB vs PV no idea about that, someone else might have some knowledge to share.

From my point of view, the Agx color management is quite seducing. Nice highlight falloff, colors OK, i like the desaturated aspect as will on high values.

I most of the time use your AgX matrix (thanks) + custom 1D curve made with Lutcalc, and it works quite well.

I also tend to have little photoshop editing at the end, so i like to have my colors right in the render, and i find it very hard to finetune them in the VFB.

So i thought of finding the nice color setups with a lut in Resolve, and then bake them with AgX in one single LUT.

are you using Corona Image Editor?

Thanks for this James, I have checked the scores and my colleagues Mac should only be twice as fast. The issue here is that he seems to get faster renders through Corona VFB than PV whereas I don't. I am wondering if I am doing something wrong?

At least I know from those results you have posted it definitely isn't anything to do with only having 32gb RAM which I suspected.
