Hello yo_bi,

Could you please specify which platform are you using? Also, it also might be helpful if you can share the image so we can have a look. Thank you.

You need to make an alpha mask or use the alpha channel of the PNG (if present) as the source for an opacity map inside your VrayMTL. I'm just guessing here because I have no idea what you are trying to achieve.

In the case of the PNG you send (it has the alpha already baked in, so no channel to work with)

- Duplicate your Vraybitmap
- Set your RGB and Alpha Source of the duplicated map to Alpha as Gray (RGB output), and Alpha (Mono output)
- Plug this map into the opacity slot.
-...
- Profit
