Thank you very much pokoy!! It might be tedious but it's a lifesaver for the moment!
I've been using 3dsMax since version 1 and I think I never used the minimize button on material editor... I always open and close it :)

I've tried with  scanline renderer and it does the same...
But now I noticed that the brackets are missing only from the first parent node of the material, while the children appear correctly.
Unfortunately, that doesn't help me much, because sometimes I assign for example a multi-sub material or a Corona layered material to an object and only one of its children material to another object. So, if I use the "select by material" button, I'm not 100% sure that I'm selecting exactly what I want...

Hello,
I have this issue since I updated Max 2022 to version 2022.1
When I pick a material from scene in the slate editor, it has no angle brackets, like if it is not assigned and also the button in the editor to select by material is grayed out like if the material is effectively not assigned... but if I assign it to a random object, then the brackets are shown and I can use the "select by material" button again, selecting all the objects that have the material applied.
If I clear the material editor, it forgets everything and does the same issue again... (it does it with any kind of material)
Does anyone have the same problem, or any suggestion?
Thanks in advance!

Patrick

Thanks Tom! I was just experimenting with that as I had some free time but I must say that in a test scene it works pretty well also with screen space! But of course everything works well in test scenes with teapots... problems always occur in production! ;)

I just noticed that the problem doesn't occur in a directly visible object but in a mirror! Maybe the solution is to be searched in other parameters, related to reflections and not to the light itself?
It remembers me of a similar problem I had with an object that had a displacement applied and which looked bad in a mirror that showed its back side. Unfortunately in that case I modified the object instead of looking for a solution for a more precise reflection, and so I don't know where to point you for a possible solution... Sorry

One thing I usually do in my scenes to avoid similar problems is to create a simple and rough bounding box (of course with holes for the windows...) around the interior. I found it useful expecially for actual small holes or misallignments that I may have left in the geometry...
I assign it a neutral gray or black material without reflections to avoid useless calculations or unwanted light bounces.

Hello Maru,
I tried using IES with Corona lights as you advised and I like the result very much!
I just found out another little bug doing it: when I have several Corona lights with a IES file loaded and I decide to "make unique" a single one of them, it loses the connection with the IES file becoming a normal Corona light and I have to reload it manually...

Hello Maru,
I'm glad you could reproduce the issue... I went on holiday and forgot to check the forum for answers to my post!! Sorry... and thank you for your advices!!

[Max] I need help! / Minor issue with photometric lights
« on: 2020-08-04, 10:52:23 »
Hello everyone,
I always have a problem with standard photometric spotlights in my corona scenes; I use them when I need narrow beam light angles because with Corona lights I would introduce too much noise if I increase the directionality too much.
I setup photometric lights using Corona shadows and I activate Corona area shadows.
The problem is that, whenever I make a copy of a photometric light, the new light has the area shadows deactivated. By now I know the problem and remember to check them but sometimes I miss one, with the result of some ugly hard shadows in my final renders...
Does anybody have the same problem? (I use Max2019 or 2020 and Corona 5)
Also, maybe someone can advice me on how I could make narrow beam lights using Corona lights instead of standard lights?
Thanks for any help/info!
Best,

Patrick

Thank you both for your answers!
Yes, I've already increased IOR, maybe even too much; the problem is in the lighting, as my client wants evening light, soft illumination, strong reflections and no overexposed areas all in the same image… no comment!
I'll try adding hidden illuminating planes; I just hope that if won't mess the scene because I render different cameras from the same scene and those tricks sometimes work from an angle but look awful from another… I know I should place different reflectors for the various cameras and turn them on and off but I never have time to refine things as much as I would like because of short production times…
Thanks again!

[Max] I need help! / How to boost reflections?
« on: 2020-04-10, 12:28:29 »
Hello everybody,
my problem is the following: I need to render some interiors with wallcovers and textiles that have  metallic effects, silk and other materials with particular reflections, like in the example images.
I make good looking materials in a testing scene but in the rooms that I have to render, there is very little exterior hard light (if at all...) and the illumination is mostly diffuse, with recessed led strips and a few small cone spots, so the reflections don't come out very much, even if I exagerate them.
My workaround is to render a reflection render element and add it in Photoshop where I need it, but I'd like to know if anybody has a way to do the same thing directly in 3dsMax with some material that can add reflections on top of the base material to boost them even if it's not physically correct. If I remember well, there was something like that in Vray…
Thanks for any suggestion!
Best regards,

Patrick

[Max] I need help! / Re: [RESOLVED] 32 bit to 16bit (2019)
« on: 2019-12-16, 10:09:24 »
Maybe I'm making a useless comment but I'd like to share my workflow for 32bit images in Photoshop. It works very well for me:
1 I save .exr images with all the extra channels I may need (reflect refract, etc.)
2 I compose them in Photoshop in 32bit mode adding reflections where I want and other general corrections
3 I group all layers and make the group a smart object
4 I convert to 16bit and when Photoshop asks if I want to flatten the image I say no; in that way the colors are preserved (at least to my eyes...)
5 I make further corrections using Camera raw and other filters that will always be editable since they are applied to the smart object
6 If I need it, I can always open the smart object and make further adjustments to the 32 bit layers and when I close it the 16 bit image will be updated
7 I save a final Jpg


This is common and smart workflow, but I will comment on this because I've seen one big misconception people have about this concept:

-Photoshop doesn't work in bit-depth of the smart layer, but only the actual environment. So there so no dynamic range available with adjustment applied to this smart layer within 16bit mode, the dynamic range is only available within the smart layer environment (if that is retained as 32bit).
-CameraRaw adjustments like Highlight compression,etc.. are thus working the same way as if you applied them to jpeg (because both 8&16bit PS environment are clipped integer gamma-corrected environments).

You're absolutely right! Dynamic range adjustments need to be made exclusively in the 32bit environment. What I do in 16 bit are only final adjustments that are more difficult or imposible to do in 32 bit mode, like white point compensation, that camera raw handles well and easily or a little bit of smart sharpen in certain areas of the image... Also, I think that working in camera raw in 16bit works much better than in 8bit because of the higher color depth; it's like working on .dng images from cameras instead of jpgs...
