[Max] Feature Requests / Re: Masks for Decals

« on: Yesterday at 10:45:22 »

You mean render elements, right? You would like to render your image and have decals as masks so that you could for example select a specific decal in a 2D editor?

Exactly! In my case, I have used a decal to create crossing lines for pedestrians in a road. The road is the main object with an asphalt as a material on it and the decal is the crossing lines. I wanted to lower down the exposure of that crossing lines in Photoshop but the selection on anything else except Monochrome or RGB masks doesn't give me a detailed mask. As a result the lower exposure adjustment creates a frindge-like effect around the crossing lines.

[Max] Feature Requests / Masks for Decals

« on: 2024-04-25, 16:24:01 »

Hello,

I would like to have the ability to create a Monochrome or RGB mask from Decals in the future. The ID Mask is basically unusable when it comes to color selection in Photoshop.

Thanks

[Max] Bug Reporting / Decals not visible in masks

« on: 2023-05-26, 13:17:49 »

Hello,

I have found out that decals are not visible in masks (RGB, monochromatic, Wirecolor and ID (Material ID)), even if the option is checked on their properties. The only exception is Mask ID with "Instance ID" selected.

According to my tests, RGB, monochromatic, wirecolour and ID (with Material ID selected) don't work. Which they should. Sure, Mask ID (with instance ID selected) can do the job but that doesn't mean this isn't something that has to be checked and possible be fixed. What if I had to make RGB masks for animation for example?

Thanks for your help!

Cheers!

Indeed it works. Why it works only with this setup though?

Hello Romullus,

No, as I mentioned, it is checked on.

Hello,

I am trying to create a mask for a decal but I can't find the way to do it.
In decal's object properties the "visible in masks" is checked. In assigned material everything look normal.
The decal is visible in beauty and reflection elements. However, no matter what mask I am trying to create (RGB, Monochromatic, Wirecolour, MaskID), it doesn't show up.

Corona 9.1, Max 2023.3.3.

Any idea?

Thanks,
Christos

Hello,

Have you tried to compare these file opened in Photoshop or any other "more legit" software? Maybe it's an issue caused by Windows' photo viewer.

Cheers

Yeah my fault. I got what you said. My previous post was just an idea. It was not connected to what you wrote :D
I don't mind that Shadowcatcher captures GI. I might be ok with it. However, what I don't know is if objects with Shadowcatcher material on them contribute to scene's GI.
If I apply shadowcatcher to whole object of that tall building on the right, will it contribute to scene's GI?

What do you think of the idea of having a visible simple grey geometry for GI purposes and a simple plane few milimeters away with an invisible shadow catcher material?

Hello,

I would like to hear your ideas regarding a technical issue we have to solve.

We lately work on a project of a holistic renovation of two attached buildings plus a new pedestrian bridge which will connect these two buildings with a 3rd building across the steet.
We have been asked to create in 3d the renovated buildings and the bridge and compose them into real photos.
In order to recreate the same lighting conditions we have created, in simplified form, the buildings of the neighborhood. We have also created the building to which the pedestrian bridge will connect.

The problem we face is that the new bridge casts some shadows to the connected 3rd building across the street. We want to keep these shadows in order to add them on the real building which is an existing building and is part of the real photo we want to keep. I know the existance of Shadow Catcher, however, any related online available information talks about how to use it on simple planes. We also want the geometry of the simplified building to keep contributing to the GI of the scene.

I am not sure I explained the situation clearly so I am attaching some photos.



I know that the simplest answer could be to just paint some shadows in photoshop, but what is the legit solution to this, if for example we had to create an animation of it?
How would you approach it?

Cheers

Thank you all!
Indeed I should count as sensor width its height as long as I took vertical photos.
Actually, I thought of it while I sleeping (heh...)
Thank you for the extra information too!

General CG Discussion / Impossible to match real photo with 3d camera

« on: 2023-04-28, 00:30:00 »

Hello,

I have an issue that drives me crazy... I am trying to match a real photo I took with a 3d camera.
I know what camera was used (mine, canon RP), I know the lens was used (tilt/shift 17mm from canon), I know the spot from which the photo was taken because I took it, but still if I set Focal length to 17mm and film width to 36mm the result is night and day...The problem is not about the shift effect of the lens, the problem is that 17mm at 36mm is much wider than the actual photo.
The 3d camera matches approx. at 26mm focal length. Have a look at the attachments. Any idea why that happens?

Thanks!
