Topic: Transparency and Materials proyection...

[Kurgan]

Hi guys,

1- There is a way to control de opacity of the glass material?

2- How to do a alpha channel material to control de opacity?

3- Can I control the proyections of the materials applied?, that is, seems to be a rectangular proyection, can we apply a spherical or cylindrical proyection?, and can we control de size of the material in the X and Y and Z axis?....

Thanks so much in advance (And sorry my horrible English)

yes please tell?
I was hoping that there would be an opacity slider somewhere. I thought that this would be a standard.
the only transparent material/textures are the glass options.

Sorry guys, but scream, this has been discussed a number of times, please search  the forum.

Perhaps Morten can help by adding a sticky in FAQ on this topic.

1- There is a way to control de opacity of the glass material?

There's no dedicated opacity slider at the moment. The darker the glass is, the less transparent it will be.

2- How to do a alpha channel material to control de opacity?

Import a model with a diffuse texture that includes an alpha channel, (eg, a 32-bit TGA texture).

Lumion currently only supports 1-bit alpha channels (black pixels = invisible, White = visible)). Greyscale tones in the alpha channel will be rounded up to 100% white or rounded down to 100% black.

If your model already is in Lumion, just apply a Standard material to it, load the texture with the alpha channel (Texture tab -> Change Diffuse Texture) and set the Reflection or Clip slider to Clip (the maximum slider value) to turn on alpha clipping.

3- Can I control the proyections of the materials applied?, that is, seems to be a rectangular proyection, can we apply a spherical or cylindrical proyection?, and can we control de size of the material in the X and Y and Z axis?....

No, more advanced texture mapping needs to be applied in your 3D modelling application. Then use the Reload model button to update the model in Lumion.
