There are a few ways to do this. I will explain for blender but other apps can use a similar approach.

Option 1
Add a transparent shader to your base shader via a mixshader node. Add a value node to the factor input of the mix shader. Animate the factor value.

Option 2: create two wall objects. Wall A will have an opaque blend mode and wall B has an alpha blend -blend mode. Animate the alpha value of wall B.

Programming for option 2: 10 frame fade.
At frame 0 wall A is visible, wall B is hidden. Frame 1 wall A is hidden and Wall B is shown. Animate alpha on wall B to 0 at frame 10.

The above should be in a procedure you can call when the camera rotation value crosses thresholds that define when you want the wall to fade in and out.

it’s not a trivial task to make it with the Verge3D engine. The alpha blending with multiple objects is a capricious thing. but it’s possible. and it costs a lot.

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.
