"Show Map On Back" doesn't work

As title said.
There is no info about that on help pages...

Hi, thanks for posting. What DCC are you using? (for example is it 3ds Max). I am not sure what do you mean? Could you explain you issue in a bit more details? On my setup, using 3ds Max 2024 and V-Ray 6.10.08, VRayBitmaps are visible on the backside of the faces in viewport and render.

3ds Max 2020.
The point is that when "Show Map On Back" is UNchecked bitmaps shoud NOT be visible on backside faces.

Hi, it seems to work on my setup with V-Ray IPR and production rendering:

With the 3ds Max's viewport preview it does not.

You're leaving the box ticked

The OP is pointing out that it does not work when the box is not ticked, which should make the back side invisible, which can be useful in some situations.
Only scanline works in this regard.

The Vray option is to have a 2sidedmaterial with the back side using a vraycolour set to black

I am switching if off, watch the video. With the checker off it shows the grey diffuse colour on backside faces but only in render. Viewport does not work.

My apologies, I didn't realise it was a vid.
Weirdly it doesn't work for me using Max 24.
It happens in the ME preview but not in render.
