[Max] I need help! / Light Lister Grouping
« on: 2020-11-16, 20:43:21 »
Am I doing something wrong cause my Light Lister shows all lights in a scene instead of grouping instanced lights together.  I have a TON of lights in this animation and Light Lister looks crazy with all the lights listed and hard to work with.  It also doesn't seem to list the sun which is a light?

[Max] I need help! / Glass with Liquid
« on: 2020-11-13, 21:32:06 »
I can't believe I'm having problems with this, I think I've done it a million times. But I have a glass with liquid and it looks good for it's purpose, but when I attach the liquid to the glass ( poly > Attach) the liquid disappears.  I can't believe I'm having issues with something so simple.  Liquid in Glass is slightly larger to move into the glass itself.

[Max] I need help! / CoronaUvwRandomizer SLOW renders!
« on: 2020-11-08, 01:17:02 »
We are working on an animation right now of a Clubhouse, exteriors and interiors.  Render times where getting long, couldn't understand why.  I started in on a new room, locker room, and only added one texture so far.  The wood texture for the lockers, and off-set the texture U & V using CoronaUvwRandomizer node.  Works like a charm but render times where 8 minutes a frame.  I then realized all renders where taking long due to the CoronaUvwRandomizer nodes we are using.  I removed the CoronaUvwRandomizer from the shader then the render time went from 8min down to 1.5min.  Is this normal for the CoronaUvwRandomizer to take so much longer to render?

[Max] Feature Requests / Can we possibly have Flare effect?
« on: 2020-05-08, 17:25:23 »
I used Redshift for quite some time, one feature I thought that was nice added to it's PostFX of Bloom and Glare in the VFB was the addition of Flare.  I know there is a new Bloom and Glare coming with Corona 6, and I'm sorry if this was requested already but I think it would be a great addition.

[Max] I need help! / Denoiser with Render Farm
« on: 2020-02-14, 18:54:17 »
Hi I'm rendering an animation with a renderfarm Rebus, I always use Nvidia GPU denoiser.  Unfortunately I received back my animation with no denoising cause they have no Nvidia GPU on nodes.  Is there a way around this? maybe save out the render from the farm to a .cxr file and run it through Corona image editor, would that denoise the images?

[Max] Bug Reporting / IPR is getting really bad
« on: 2020-01-30, 19:04:06 »
IPR seems to be getting really bad, that in some scenes I cannot even use it anymore with Slate Material Editor cause it lags so bad working with materials.  It seems to keep getting worse and worse with newer versions, Vray on the other hand is snappy as can be.   It also seems like it doesn't respect excluding CPU cores for system, it seems more snappy at fist with excluding cores but then gets just as slow a few seconds in.

[Max] General Discussion / Calculate Ray tracing on GPU?
« on: 2019-11-09, 20:17:33 »
I am not a programmer, so this might be a stupid question. I was wondering if it was possible to offload the calculation of raytracing somehow to the GPU especially with the new RTX. But the CPU calculate everything else? But for what takes the most time, Ray tracing, calculate off of the GPU. Like I said I'm not sure if it's plausible to offload just one area of rendering but if it is it seems that way cut render times considerably. I'm sure the Corona team had even thought of this or even know this is not possible, was just wondering and there's nothing wrong with being educated on it. :) Thanks again for a fantastic render engine.

[Max] I need help! / Anima rendering with Double motion Blur
« on: 2019-08-14, 07:33:44 »
Hi I'm rendering with corona-5-3dsmax-daily-2019-08-07 and the scene has Anima characters and all the motion blur on them are doubled, looks like double vision. Don't know what to do.

[Max] I need help! / Rendering out Previz
« on: 2019-07-18, 22:30:30 »
We are rendering out Previz for an animation we are doing, so we set rendering for 30 sec. Renders fast and good quality, but the "Parsing scene" ruins it by how long it takes.  Now I see there is something on the roadmap about fixing Parsing Scene to be quicker.  In the meantime is there a workaround or something better to use ? Can one render out Previz from IR since you can set it's Passes? Seconds would be better in case some shots take longer to clean, so you can make sure everything only takes 30 sec.

[Max] General Discussion / Vray Next vs Corona 4
« on: 2019-04-28, 00:14:18 »
Wanted to get you guys opinions on Vray Next since most of you came from Vray or still use it but also use Corona.  We own Vray 3x version and Corona among other renderers.  We are going to keep using Corona but might use Vray Next for animations. Had some observations and questions.

We just used Corona 4 nightly for an animation, render quality, user interface & user friendliness is fantastic. Render times get to be quite large compared to Vray Next that we tried for a few small tests, and that can really add up for animation.  Vray Next IPR seems much more responsive and final rendering seems to be much faster.  But my question is about quality, many Corona renders look very realistic compared to Vray.  Not sure if this changed with Vray Next, but I can't place my finger on if it's Coronas lighting or shaders.  Seems to have more depth and reflective properties seem more natural. Like I said we had only limited time with Vray Next trial, so for those who use both would love to hear your opinions or even see you comparisons.

[Max] I need help! / Opacity Clip Slow
« on: 2019-03-28, 19:18:51 »

We have an animation we are working on where we have a lot of vegetation. We are using Opacity maps for the trees and utilizing the clip option.  The problem is that it is still very slow to render.  With opacity with clip is 2X slower than turning off opacity.  Is there a better way or something that can be done?

Hardware / 1950x CPU Utilization only 52%
« on: 2019-03-20, 22:10:46 »
Hi I noticed that my scenes I have been rendering have been rendering slower and slower for some reason,  I figured it was just that much more detail I was adding to the scene.  But then I checked my CPU usage and it says it's only running 52% at 1.97GHZ, I have a 1950x OC'ed to 4GHZ.  I attached temps from HWMonitor. Do you think My CPU is throttling or is it something else?

I have noticed that rendering with Corona Sun/Sky is a lot slower than rendering with an HDRI. Why is that? I would of thought it would be the reverse.

[Max] Bug Reporting / Constant Freezing and crashing
« on: 2019-03-10, 00:09:44 »

I am getting constant freezing during IPR and rendering.  It still calculates the rendering and IPR but freezes Max until a few minutes until it comes back.  Doesn't happen every time but it does happen 50-60% of the time. Once in a while I will get a full Frozen crash where you cannot even move your mouse and it never returns.
