Question Set mesh transparency

[tradx]

Dear all,

I would like to customize the transparency of a given mesh group. What I have tried so far is to modify the opacity of the mesh material, i.e. parameter “a” (one of the 4 RGBA colour components) which controls the opacity of a given material spec (diffusive, emissive, specular…) but can’t see any transparency modification on that group. The only thing I have managed to achieve is to change the colour of the mesh (with the help of BrianJ’s Red Dragon code) but not the transparency
Any inputs on this will be more than welcome

Thanks Orbiters

Hi,

I don't know if it's possible to have a transparent material in Orbiter but I do know you can make objects transparent (or slightly transparent) by the use of opacity in textures.

As far as I know, transparency in orbiter is achieved by texture transparency (i.e. alpha-channel in a DXT5 file).

this is the setting for some glass with .10 transparency

0.329412 0.941177 0.941177 0.098039
0.329412 0.941177 0.941177 0.098039
1.000000 1.000000 1.000000 0.098039   0
0.000000 0.000000 0.000000 0.098039

9
I think the last set of numbers determines that
0.09803

Ah... The alpha channel of the diffuse color controls transparency. So logical that I'm baffled that I didn't think of it... :facepalm:
