Topic: opacity map

[airnan]

Hello again,

I'd like to know if there's a way to actually use a short of opacity map in Lumion engine, or if it's even a posible feature that could be added to future versions.
I was thinking on how I could make a map that, for example, shows a mesh as a metallic mesh (one of those fencing meses, see attached image) without modelling a real 3D mesh, just using an opacity map.

Hi airnan, this is indeed possible.

You'll need to create a 32-bit texture with an 8-bit alpha channel that will act as a clipping mask.
Make sure that the diffuse texture is a 32-bit texture that includes the alpha channel, e.g. TGA/TIFF/DDS.

In Lumion, assign this texture to the first texture slot in a Standard material.

Then set the Reflection/Clip/Bright slider to 0.5, so that the alpha channel is used as a clipping mask.
