How to make objects single-sided? (to look through a wall into a closed room)

BenediZ — Thu, 24 Oct 2019 20:45:54 GMT

Hello,

I am coming from Maya and am Beginner with Max:

1. How can I make geometry single-sided, so that the camera can look through it from one side?

2. How can I get a second viewport window on a second monitor?

Many thanks

Regarding q1, you can simply hide the wall you want to see through or adjust the camera near clip distance till the wall disappears.

Hi 10Dspace,

many thanks, but hiding is no option, it's not the same:

I want it's shadows and reflections and everything to be rendered from one side but from the backside (the opposite side of the normals, from where the camera is looking) I want to look through.

It means that the object is also visible to the camera everywhere, where the normals face the camera. Otherwise the wall of the room at which the camera looks, becomes invible.

near plane clipping is a workaround, but not very handy.

Anyone else knows?

I am not at my computer now but did you try unchecking "visible to camera" in object properties. Also search on creating a matte object in max. I've done this before but can't remember details right now.

The object needs to be visible for the camera from the other side.

In Maya I can additional check, to have it visible from one side and not from the other (and choose if normals direction or opposite), something at the properties...

So it seems there isn't that feature here.

Thanks anyway

First question:

If the wall is a single sided object hen->Object Properties->Backface Cull

Second question:

Thanks, but I don't have this Floating entry!

Watch my panel (Max 2020)

Please upgrade to the latest version of 3dsmax, which is 2020.2

Hm, I downloaded and installed Max only a few days ago and I went on "Help > check for Updates" and I find no new option.

See screenshot. Very strange, should be shown there, when you search for updates.

But now I logged in and manually searched for update 2020.2... let's see how it works...

thanks

You should also get it using Autodesk Desktop-App.

- Tearing off a panel worked, thanks

- The functionality to have single-sided objects, where I can see only the side of the normals, which is facing me, I still did not find. At least not with vray rendering...

When reversing normals, I can look into it in the viewport, but it renders grey for vray. I ticked double-sided already of in the material

For the viewport, @Anonymous gave you the answer which is to check backface culling in the object properties dialogue and you have verified this. However apparently Vray ignores this which has been documented in the various message threads on the net. (Search "Vray ignores backface culling".) There were a few messages there about an earlier scripted solution for Maya, but in a (really quick) search I didn't see anything for Max. Maybe you could contact Chaos for the latest in case there is a solution.

I'm was asking at vray forum, too. It seems to me, there is no solution right now...

at least nothing obvious (I also tested with 2-sided material, which was another tip)

Select object you want to make a single-sided. Right mouse click in viewport and select Object Properties from pop-up menu. In opened Object Properties window check in Backface Cull in Display Properties. Make sure the material you applied to the object is also single-sided material. Otherwise it will override the display properties when you render this object.
