The sun is just a sun texture on a quad rendered with additive blending.

I don't get it :( I've do want to make an object that shines like the sun of the magic island, but I don't know how...

have tried convinations of these lines:

Code: [Select]

    //shot.setBillboarding(Object3D.BILLBOARDING_ENABLED);
    //shot.setVisibility(Object3D.OBJ_VISIBLE);
    //shot.setCulling(Object3D.CULLING_DISABLED);
shot.setTransparency(10);
shot.setTransparencyMode(Object3D.TRANSPARENCY_MODE_ADD);
    shot.setAdditionalColor(com.threed.jpct.RGBColor.GREEN);
shot.setTexture("green");
shot.setSpecularLighting(true);
    //shot.setLighting(Object3D.LIGHTING_NO_LIGHTS);


any tip?

thanks in advance

Looks ok. Maybe you can post a screen shot that shows your problem, because i don't get it ATM.

I probably didnt explain it correctly. I want the spaceship shots, the green and orange ones, to shine like the sun, or make a similar effect of the multiples light sources on an3dbench.
thanks in advance

You are adding green to black. It doesn't get greener than green that way. The benchmark adds colored dots to a none-black background, which makes it look more intense. Try to use a texture that has a color fading towards the edges and maybe don't use 10 as a setting for the transparency, because that makes the fading almost opaque. Try 0..3 instead. It won't be any brighter, but it might look more like you want it to.
