So i'm trying to write a skybox and an environment shader, but im having some issues finding out how cubemaps work with Kha and G4. I've searched high and low in the documentation, source code and examples. But i have not found a solution yet..

myCubemap = CubeMap.createRenderTarget( ... ) is the only method available it seems, and im not sure how to actually set the 6 images you need like you can in WebGL using GL_TEXTURE_CUBE_MAP_POSITIVE_X etc...

I guess you would use g4.setCubeMap(pipeline.getTextureUnit("cubemap"), myCubemap) to the set uniforms... and i got this far but not further.. I've seen that Armoury3D does use skyboxes do im guessing it should be possible?

If anybody has some insight into this i would really appreciate it!

(Im still learning G4 workflows, so bear with me :p)

createRenderTarget is a strong hint at what to do - you have to render into them. We still haven't provided a method to directly load cubemaps from a file (even still have to think about how the files would have to look because the whole process is different in different graphics APIs).The cube map has a g4 element and g4 has a beginFace method.

Oh, i see! Well, that works just fine ! Thanks a lot!

Cool Spot!

Hey, another question... While cubemaps using the render method described above works fine, how do i set mip levels for a cubemap? Image has a generatemips and set mips function, but cubemaps do not... Not possible at this point? I really need it for IBL specular light among other things!

Hmm, yes, that's definitely important. Please open a GitHub issue, will try to get that in soon.

Great, thanks! Will do!
