[Pharo-dev] Transparent colors with NBOpenGL?

Hi! Is there a way to have transparent colors with NBOpenGL? I’ve tried the following (using Roassal 3d): -=-=-=-=-=-=-=-=-=-= | view el1 el2 | view := R3View new. el1 := (R3CubeShape new color: (Color purple alpha: 0.2)) element. el2 := (R3CubeShape new color: (Color purple alpha: 0.2)) element. view add: el1; add: el2. el2 translateByZ: -2. view addInteraction: R3MouseControl new; addInteraction: R3KeyControlForMac new. view open -=-=-=-=-=-=-=-=-=-= But I get something like: Would it be possible to have translucent cubes? Any OpenGL expert around? Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
