[Max] Resolved Feature Requests / Color Correction

« on: 2019-01-18, 10:52:45 »

Just out of interest; why does the Corona Color Correction node not have the capability to change the hue (similar to the slider in default 3ds max colour correction)?

What am I missing that means we can't do this?

[Max] I need help! / Scale and Corona

« on: 2019-01-17, 10:34:06 »

Sorry if this is more of a 3DX max question...

I work exclusively in MM (millimeters). So often when I buy a 3d model and open it, it's in CM units. Therefore I get the 3DSmax dialogue asking to adapt to the files scale or re-size it to my system scale. I almost always of course choose to have the model re-scaled to fit my MM.

My query is; do the Corona materials (or any materials) get automatically re-scaled in this process too? Or do I need to fix these myself?

Any tips appreciated.

[Scatter] 3ds Max - Bug Reporting / Corona Distance Map + Cscatter

« on: 2019-01-11, 10:58:53 »

Hi All,

Apologies if this has already been reported/queried...

I'm finding that using corona distance map in the scale map of a corona scatter only works when the scattering is set to "2D - On surfaces". It does not seem to work when scattered inside volume or on splines. Why is this? Is this a bug or a known limitation? What can I do to get this to work as expected?

Thanks.

[Max] Feature Requests / Lightmix should correspond accurately

« on: 2019-01-04, 10:14:25 »

Hi all,

Can the Lightmix 'colours' in the VFB accurately correspond to the actual colours/temperatures of the lights?

This seems like a no-brainer to me. It would make the Lightmix feature easier to use and more powerful. Understandably, the Environment slot is a bit more tricky to deal with, but with regular lights, or basic environments it's current incarnation seems counter-intuitive.

Hope this is clear. Looking forward to feedback on this request...

General CG Discussion / Hello Estonian 3D artists

« on: 2018-12-17, 08:30:11 »

Hi Guys,

I know there are a few Estonians occasionally using the forum here...

I'm slowly organizing an Estonian 3D Artists group over on Facebook. If you haven't already joined, please do.... we're currently arranging our second get-together sometime next month.

So far it's been great hearing from other local 3D artists about their stories, software and so forth.

(I hope I'm not bending any forum rules here with this little group promotion? If so, I apologize profusely!)

See you over at 3D Rendering Estonia: https://www.facebook.com/groups/2100811730151011/

Aitäh!

[Max] I need help! / Turn off reflective caustics?

« on: 2018-11-29, 08:58:03 »

Hi All,

Is there a simple 'on/off' switch for such an effect (the light reflecting onto the floor from the metal, see attached picture)? From my research I should change the MSI to reduce it, but I don't think it actually completely removes it?

I have a bathroom scene with lots of lights, lots of chrome, and therefore quite a lot of unwanted fireflies...

Cheers,

[Max] I need help! / Simple interior lighting

« on: 2018-11-28, 09:01:08 »

Hi All,

I'm currently working on a set of bathrooms which the client wants rendered at 7k. I've never done 7k before, so I'm trying now in my early development to optimise the scene as much as possible.

I'm wondering, if I replace the door (behind the camera, only seen in detailed reflections) with a corona rectangle light as the main source of lighting, is this workflow 'acceptable'?

Attached are two quick tests. The quicker one is with the rectangle corona light (set at intensity of 1), the longer one is with basic white Corona environment. Both of these are the only source of light in the scene. (53 seconds vs 2m)

Although the rectangle light was a lot quicker (and supposedly has lower noise), there is a lot of visible noise in the reflections - most noticeably the shower faucet. Obviously, I'll be adding more lights (probably only mostly strip and ceiling lights - corona lights, hopefully no emissive materials). The noise does seem to disappear when I do zoom renders.

Any feedback appreciated. Should I, for some reason I'm unaware of, not use the rectangle light workflow? Thanks!

[Max] I need help! / Batch load textures with real-world scale?

« on: 2018-11-26, 13:22:33 »

When using the CoronaMultiMap, is it possible to somehow use the 'Batch load textures..." feature in a way that I don't have to then individually enter the real-world scale for each map? This get's a bit frustrating when I load 10+ bitmaps and have to enter the height and width manually for each...

Apologies if this has been queried before (I have a feeling it has!)...

Any tips appreciated. Cheers,

[Max] I need help! / Laggy; normal behavior?

« on: 2018-11-19, 16:45:32 »

So when rendering (basically any mildly heavy scene and upwards) my Corona VFB and Max windows get very very laggy.

Most of my other windows, inc. Photoshop, chrome, spotify, etc don't really experience any issues. But if I try to minimize the VFB or zoom inside it, or do some sort of action in it while rendering, it will almost certainly completely lock up and take approx 1 minute to perform the action. It's not necessarily a very big problem, as there isn't much I can be doing during rendering anyway, but it is a bit frustrating to not view the rendering realtime.

I'm just wondering if this is normal behavior? I've got a fairly powerful PC and wouldn't expect to experience such bad lag. My RAM almost never exceeds 32gb (of 64gb physical). Right now my 12 core xeon 2.0Ghz is maxed out at 100% usage, but my RAM is steady on 20.3 gb. But - like I said - zooming in or minimising the VFB is very very laggy.

As far as I can tell, this has always happened, from when I join Corona at Version 1.7 right up until the current RC5.

Is this just what happens? Or am I due to for a hardware upgrade?

Any pointers helpful :) Cheers,

General CG Discussion / 3DS max general help

« on: 2018-11-18, 11:55:19 »

Hi All,

So I'm basically a complete newbie when it comes to 3DS Max. I'm previously a Rhino user, but Corona sucked me in a few months ago...

Coming from Rhino, modelling in max is quite difficult for me. Every operation seems backwards, inside out and completely counter-intuitive. I google a lot, but rarely find decent answers to my queries... and almost always end up on https://knowledge.autodesk.com or https://forums.autodesk.com... both of which I think are awful. Funnily enough, these sites reflect the unfriendly UI of max soo so perfectly...

Does anyone know of a better forum for 3DS max general help and queries??

OR

Is it cool to ever discuss max questions here on the corona forum boards?

Thanks!

[Max] Daily Builds / Can't get DR working with daily build sep 14

« on: 2018-09-19, 05:26:20 »

Hi All,

I was previously using 45 day trial of Corona 2, until yesterday when I purchased FairSaaS and updated to daily build sep 14.

DR was working fine for me until the update. Now I can't get it to work. It keeps 'downloading scene' then 'starting', then 'parsing scene' then 'not working' and repeat. The error I get is " Cannot contact 3ds Max, trying again ..."

I have max/dr/corona logs available if that will help? I've done an uninstall / clean install and still no luck...

Any tips?
