I want to get glass material like this car’s windows.
http://away3d.com/showcase/detail/car_visualizer
http://carvisualizer.plus360degrees.com/away3d/

I set 0x00000000 bitmapData for TextureMaterial
and alphaBlending = true, my mesh is disappeared.

I used FresnelEnvMap, RefractionEnvMap,
but I haven’t gotten enough result.

Can anybody teach me?

sure the first 00 is alpha so 00 is completly hide
0x22000000 is transparente but black
so 0x22505022 is transparente and a bit yellow
0xff505022 is not transparent

Thanks loth.

Yeah. I know.
But, I want absolute transparent material like above link’s glass material. And that’s EnvMap’s alpha seems not so lower.

I check your racing example source, but I can’t understand the way…

On your way, Is AutoMapper important for glass material??

Hi guys,

I did something like this:

var glassReflection:EnvMapMethod = new EnvMapMethod(YourCubeTextures);//play with other type of reflections
var glassMaterial:ColorMaterial = new ColorMaterial(0xffffff, 0.4);
glassMaterial.addMethod(glassReflection);

Play with the alpha, specular and glossiness values of the material as well as the color gradient to make the glass more or less opaque, transparent and reflective. Also the realism of the material varies depending on the cube textures you use. If you use real time reflections the results can look different from some angles and probably you will have to add a little extra custom shading.

I hope this helps.

Cheers.

Thnaks Ivan.

I have tested that way too.
I think that FresnelEnvMap is better than EnvMap.

Try this too.
Cheers.

Hi Goro,

Indeed fresnel equations give better angle reflections and refractions, also help to illuminate more realistically the material without adding extra lights. It is useful if you want to make high reflective metal/conductive materials like chrome or gold, or polarized glasses. For transparent materials it is not that cool in my opinion, unless your mesh is more a concave shape and needs to have a visible IOT result at the same time that an IOR result (E.g. soap bubbles, some wine glasses or water among others situations). But it can be use for flat/planar glass as well.

If you want to have the same visuals as your example, the way to achieve it is in the way I described above. But playing with some values for your needs.

Cheers.

Thanks for explaining.
I want and tested the glass material on more complex geometry than plane.
So, Fresnel had seem better than Env.

But I haven’t get true glass like material.
The glass material that I want is like this:
* diffuse alpha = 0
* specular alpha = 0
* reflection alpha = .5
I could not set each properties separately on Away3D.
It seems diffuse’s alpha affect other method’s alpha.

Although this may be a issue of the rendering process,
I will keep researching.

If you know about this topic,
please remind me.

Cheers, and happy new year.
