See through - to have an object more trasparent

hi,

Does anyone of You know if it's possible to control the see-through trasparency of an object in the viewport ? I have a small room and need to set the camera behind the wall and the scene is a bit too dark to work on then so it would be nice to have this wall simply more transparent.
I know that there is an option of 'visibility' under 'object properties' but this also make this wall less/more visibile to rendering at the same time, which is not what I need.

thx!

ctrl+x toggles viewport 'see-through' mode of a selected object.

Or you could keyframe the object's material opacity at varying levels and use the next/previous frame hotkeys to cycle through.

when I hit ctrl + x it just goes to expert mode I presume (all toolbars dissapear).

Remember that see through doesn't really work too well if your object is double sided unless you enable Backface Culling. Otherwise it draws both the front and back faces of something like a box which makes it more opaque.

I hate that it defaults to backface culling off when working with interiors. I make all my objects backface culled on creation using the preference. It's slower to draw but miles more useful to work with.

But for full control you'll need to animate the opacity and slide the time slider back and forth as mentioned above.

ok, al+x is just turning this function on and off.
I'd like to be able to control this function so the object is more transparent in the viewport.
Now the object is transparent, but the scene is too dark. I need to cross the wall to see the scene in apropriate brigthness.

The only way u can control the opacity of an object is by using an actual material. The See-trough opacity is hardcoded, and so, can not be changed.

Would make an interesting challenge isolating this tiny little critter inside the code and hack/patch it to use some lower opacity value. It's especially annoyingly bright when using realistic mode and with gamma/exposure control enabled in the viewport ...

Damn true!
What is there not to love about all the hardcoded stuff... Who'd ever need to tweak that?! Why would anyone even want a maxscript exposure... (rofl)

Is this something someone can write a script for? Like setting the visibility to .2 and then assign that to a hotkey?

I've used this in the past, but it would still be nice to have a little more control.

$.visibility = not $.visibility

thanks guys, at least I know how it works know.

Try this

Use a shell material.
Set the Original material to be your render time material & set that to "render"

Set the baked to "Viewport" & adjust the opacity of this material as required.
Now the viewport and rendering appearances can vary as much as you like.

Hope it helps.
