[Max] Resolved Feature Requests / Re: Which V-Ray feature should we bring to Corona?

« on: 2017-09-15, 04:15:41 »

-Vray Bump Mtl (do not mistake with bump map)
https://forum.corona-renderer.com/index.php?topic=16770.msg108484#msg108484

+1 for BumpMtl  - I used to use all the time with VRay.

VRay Plane / infinity plane equivalent.

'Reset on render end..' option for CoronaDR  (we regularly have problems where we have to go around all nodes and restart CoronaDR for them to start picking up)

+1 for Aerial Perpective

VRay Environment Fog   or improvements to current volumetrics

[Max] Resolved Bugs / Re: Corona 1.6 Hotfix 2 and Noise

« on: 2017-09-06, 12:29:54 »

We have just discovered a serious bug when using the DMC sampler in 1.6.2 in DR. We'll be releasing 1.6.3 soon, where this bug will be fixed.

In the meantime you can work around this issue by selecting another sampler in the debug settings.

Regarding using the scenes in older versions, I'm not sure to be honest. If it works, you will almost certainly have to select the appropriate sampler by hand as well.

Thanks for the heads up

[Max] Resolved Bugs / Re: Corona 1.6 Hotfix 2 and Noise

We have been having the DR issue since 1.6  - having to restart the CoronaDR on the nodes for them to pick up.

Also, now since 1.6.2 we are experiencing some odd noise in scene with a lot of bounced light.  Generally we render to around 2-3% noise and then run denoiser on around 0.4.  Since upgrading to 1.6.2 the noise in the scene is worse (much uglier in my opinion too), especially with DOF enabled we are getting some really nasty noise even with a 2% threshold, which would have given us near perfect results in the past.  The denoiser makes very little difference, and seems to bring out some parts of the noise a little worse too.

I have attached a crop of what I am talking about, this was rendered to a threshold of 2% noise, and rendered around 600 passes at 5k.. The results are AWFUL.  This scene was originally set up with 1.6.1 and rendered completely fine.... (also attached)

I don't really want to mess around with debug/dev settings to get this working, its not really feasible to do this across the studio, and is kind against why we moved to Corona...

Hopefully this get sorted soon...



Would there be any compatibility issues if we rolled back to 1.6.1?

Work in Progress/Tests / Re: gently worn exterior latex paint

thanks for comment Chrizzo

This is PG1714 clear sky, i agree needs some sky interest in this case.

Question, Do you have any trick for alpha masking tops of trees, esp when leaf transparency ( sky replace in PS).   Seems like a lot of residual fog/ blurred/light areas around tree tops to deal with.   Contrast adj of the mask gets it worse.

Not done it in Corona, but guessing it will be the same as with VRay.. if you render with black background it stops the haloing around the trees for replacing the sky

[Max] Feature Requests / DR server automatic restart on render start/end

« on: 2017-07-21, 06:52:09 »

Restart CoronaDR on render end - same as V-Ray default DR option.  We are currently having a few problems with DR where jobs pick up but don't actually start, they load 5-6gb into ram then just stall indefinutly. Restarting CoronaDR fixes it straight away.  This is across multiple scenes, generally when they are quite heavy or if the previous scene was quite heavy.  So would be nice to have a 'fresh' CoronaDR running after each render.

Use localhost option would also be nice, so we can DR but not use the local machine and continue to work/render.

[Max] I need help! / Shadow catcher workflow, full CG

« on: 2017-07-04, 08:59:46 »

Hey guys, I've been searching and experimenting but cant seem to get the shadow catcher working well/at all for what I need in my scene.  And Corona seems really sluggish while I'm using shadow catcher too which has made me question whether I am doing it right.

What I am trying to do....
I have a scene with a stationary camera and a moving plant and curtain (blowing in a breeze).  I want to render the room (plant and curtain hidden) as a single frame, and then render the plant,curtain separately for a little more control and the option to switch these for different plant or wind speed simulations at a later date. And maybe shorter render times overall...

Is this possible? and if so what would the correct workflow be?

Thanks

Another image, from a slightly larger personal project.  And a letter I made from this years 36 days of type that we ran across our studio. Sadly, I'm still waiting to use corona on a proper commercial project though.

Work in Progress/Tests / Corona Sketchbook

« on: 2017-01-22, 15:02:35 »

I've been trying out Corona since just before Christmas, and over the past couple of weeks I've been doing an image a night.  Nothing too complicated, mainly just trying out different techniques; playing with Megascans, SSS and volumetric materials, procedural texturing etc.

So far I'm pretty impressed.  I've been a happy VRay user for the past 3-4 years, but so far working with Corona has been much quicker and a lot more fun.


Cheers
