[Max] I need help! / Strip / partial rendering

« on: 2023-09-07, 20:34:34 »

Hi all, hope everyone is well,

I'm writing because I'm trying to render a still image for a client. I have a pretty decent workstation (Ryzen 9 / 64GB RAM), I normally never have issues rendering still images. However, this scene is very densely populated with polygon heavy elements. I'm using CoronaProxies in the scene (to the point where I can barely tell what is in the scene), the output resolution is also not too big (it's about 2000 x 1000, any less would be too low quality), but STILL the scene is using up all of my RAM and I've been having to render this scene via a render farm. This isn't ideal for me, and I was wondering if there is a method where I could split the image into separate segments or strips that I could stitch together later in Photoshop or some other program. I've never done this before because very few scenes obliterate my RAM the way this one seems to.

Is this possible? If so, can anyone quickly run through the steps to do it or recommend a tutorial?

Thanks in advance,
Mia

[Max] I need help! / Imperfections / Roughness maps

« on: 2023-07-28, 17:23:39 »

Hi all, hope everyone is well + thanks for the help yesterday,

I'm trying to work with roughness maps to add imperfections to my materials- I've downloaded an imperfection/roughness map from Quixel and am trying to attach it to an empty base material but I'm seeing no change in the render, even though the Roughness map is set to 1.0. Any ideas as to why this is?

Follow up q: Most materials I work with normally have a preset roughness/glossiness map. I was wondering how I would be able to add an imperfection on top of this native roughness. Since I haven't been able to get the imperfections to work at all I haven't tried to mix it with another map yet, but I see this becoming an obstacle down the line. I was thinking maybe use a CoronaMix or Composite map to mix the two? Would the imperfection map go in the Top, Bottom or Mix slot?

Thanks in advance!

[Max] I need help! / Camara Map per Pixel Question

« on: 2023-07-27, 16:28:27 »

Hi all,

Second question of the day... I'm curious to know how to achieve realistic foreground. Normally I would use a combination of different Scatters and Megascans for a result like this, but I think this might be using Matte Painting techniques. I asked the creator and they responded that they use something called "Camara map per pixel" for these results but I haven't found any leads or tutorials online that help me deduce how that might achieve realistic grass, dirt, etc. other elements to use in the foreground.

Any ideas?

Thanks in advance!

[Max] I need help! / AO question

« on: 2023-07-27, 16:23:38 »

Hi all- hope everyone is well.

I'm attaching a render made by an Argentinian studio. I'm aware that they use Corona. I'm wondering how they created this irregularity on the edges of the concrete slabs on the ceiling (outlined by me in green). I suspect that it was done with an AO map? Perhaps using Maps rather than colors? Anyway, I'm a little lost and was wondering if anyone had any leads as to how this is achieved. Thanks in advance!

[Max] I need help! / Shadows/Lighting

« on: 2023-02-03, 03:28:57 »

Hi all,

I'm struggling with casting shadows in my renderings. I'm trying to cast the shadow of some tree leaves onto a facade, but am unable to although I've tried using different sun sizes and intensities. I was wondering if anyone knew any tips on how to achieve darker, more specific shadows, as opposed to shapeless kind of general grey shade. No matter what settings I use it seems I can't get sharp shadows of tree leaves -

I've attached an example of what I'm trying to achieve: notice the clear shadow of tree leaves on the green metalic facade of this ADU dwelling.

Any ideas welcome :)

Thanks in advance,
Mia

[Max] I need help! / Advanced lighting

« on: 2022-12-22, 14:38:48 »

Hi all, hope all is well.

I'm writing because I'd like to take lighting in my scenes to the next level and I'm unsure of how to proceed. I normally use a CoronaSun, (low intensity + large size, normally at 35/40) with a CoronaSky. I normally don't add any additional artificial lighting in a daytime scene.
There's an artist who works in Corona who has an amazing grip on lighting and I'm wondering if anyone here can advise me as to how to achieve similar lighting in an interior scene.

I'm attaching two examples of his work + 1 example of mine.

Any advice is welcome, YouTube tutorials can only get you so far!

Best,
Mia

[Max] I need help! / Scatter Inquiry

« on: 2022-11-30, 17:10:52 »

Hi all,

My question is pretty straightforward. I'm using two different scatters on the same surface. I'm using VertexPaint to distribute objects on this surface. But I need to use two different Vertex Color maps as the two different scatters should not distribute the objects in the same way on the aforementioned surface.

I'm using two Vertex Paint mods on the same surface, but only the first one is working. I then plug a Vertex Color map into the Map slot under Surface Scattering in the Scatter settings.

In the Slate material editor, I tried to set the Map Channel in the Vertex Color map to the same number as the Map Channel in the Vertex Paint modifier, but it isn't working for some reason.

Ideas on how to use two difdferent Vertex Paints to two different Scatters in the same scene?

I hope I was able to articulate that question propoerly.

Thanks :)

[Max] I need help! / Hardware question

« on: 2022-10-27, 15:13:13 »

Hi all- Hope everyone is well.

Ive recently upgraded my workstation. Im currently working with a 12 core, Ryzen 9 processor and GeForce GTX 1660 Super. I currently have 32gb RAM installed. However, its taking over 9 hours to render a fairly simple scene. According to Task Manager, Im using about 9% of my CPU capacity and 2% of my GPU capacity (image attached). Im at a loss, really.

The same scene was rendered on my laptop (i7 4 core Intel processor, GeForce GTX1080 and also 32GB RAM) in just over two hours. My IT guy (who is not too familiar with Corona) told me that my workstation needs to upgrade GPU- I was lead to believe that Corona was a CPU based renderer that relied more on the CPU than GPU but he argues with me on this. Others have said that its because Im running Windows 10, but, my laptop runs Windows 10 as well and renders fine.

Also: My C: disk (XPG Spectrix S40G 256GB) has 40.7GB free of 256GB. Perhaps its a Virtual memory issue?

Any ideas?

Thanks in advance,
Mia

[Scatter] I need help! / Corona Scatter Problem

« on: 2022-06-14, 15:43:20 »

Hi all,

I'm having a problem with Corona Scatter. I'm attaching a screenshot- basically I'm trying to distribute 1 object on a plane (in a very simple, straightforward scene), and the scatter will distribute the object everywhere except the plane.

Any ideas for resolution? Thank you!


UPDATE: Objects modeled in Max will scatter properly (a cone, a torus, etc), the problem occurs when I try to scatter imported assets (Trees from MaxTree). They will scatter, but completely off-target.

[Max] I need help! / Exterior High Rise Render

« on: 2022-05-24, 23:13:19 »

Hi all,

I recently came across an exterior Corona render that I found to be particularly impressive. (It was rendered in 3ds max + corona I've been told), I proceeded to look for a tutorial online for a render of this style, (exterior + urban setting + high-rise architecture) but am coming up dry.
I was wondering if I might post it here an discuss what methods the forum thinks were used to produce this image + context?
Also if anyone has a tutorial that they can recommend I'm all ears

Thanks!

[Max] I need help! / Render Elements malfunction

« on: 2022-05-09, 15:01:05 »

Hi all,

How is everyone-
I've been having a problem with render output: I'm trying to render render elements (i.e. Masking ID)- it's a single render element but when I enable render elements I'm met with a fatal error that reads "The path of the following render elements have either an illegal character in its path or filename or the path does not exist - The render will be aborted." This is not true, because when you disable render elements and just render beauty without any additional elements, it will output to the same file path without issue. I've tried changing the render element name, (from C_Masking_ID to Matid, although there aren't any illegal characters in either name...) but still, no dice. Attaching screenshot of the fatal error.

Has anyone else had a similar issue? I'm convinced it must be a bug... I've never come across this problem before and it really throws off my post production process.

Thanks in advance!
Mia.

[Max] I need help! / Natural lighting advice?

« on: 2022-04-11, 17:42:39 »

Hi all, I'm very new to Corona and so far am very impressed with the results I'm getting! Currently, as practice and to get the hang of the software, I'm trying to replicate scenes other people have rendered.
I'm having a little trouble illuminating the current interior scene I'm trying to render... No matter where I place the sun in the scene, the shadows are harsh and I can't get the sun to illuminate the entire scene. I'm attaching an image of my result and the reference I'm trying to accomplish. The reference image is much brighter and the shadow from the window pane is much more diffuse. My result is darker and the shadow has more of a straight edge.
Thoughts anyone? Thanks so much in advance, this forum has been really helpful to me already!
Best, Mia.

* Note: The reference image was rendered in Vray but I don't see why Corona wouldn't be able to achieve a similar or better result. ;)

[Max] I need help! / Artificial Lighting trouble

« on: 2022-04-10, 17:43:31 »

Hi all-
I'm new to Corona, and am having trouble with artificial lighting. I'd like to produce a warm, diffuse lighting from a lamp and am attempting to use a CoronaLight to achieve it, with no luck.
I'm attaching an image of the desired effect vs my result. There is a Disk shaped CoronaLight in my scene emitting light, but no matter what the intensity setting is, the result is always very harsh and produces a hard-edge around the light. I'd like the result to be more diffuse. Tips? Tricks? Tutorials? Thank you so much in advance!!!
Best,
Mia.
