How can i create a cube map texture (samplerCUBE) in jitter? I want to make a simple environmentmapping-shader with 5 videos and one picture.

cube-environment-mapping

use jit.gl.plato and make a custom texture with the preferred 

mapping. or look at the method used in the jit.gl.render.cube 

example, which serially runs six matrices directly into jit.gl.render.

Hi,
This is not possible with the current version of Jitter without
writing it yourself.

If you just want to show video on a cube, what Joshua suggests will

work. If you want to use a cube sampler to do reflection or

refraction, then that is not possible right now.

yes i want render a video environment on a water surface and other geomity but a spheremap is not suitable for this.

Hi all, please do tell me that with Max 7 it's possible to have a cube texture to be sampled with samplerCube, this would make me really happy!

Sorry solved, somehow was scared by the fact that jit.gl.cubemap doesn't accept textures as inputs

yeah, that's a long standing feature request

One more thing dear Rob: it seems to me that jit.gl.cubemap sets the bit depth of the textures inside to something lower than float16. Is that really so? I'm doing BRDF and need to sample an hdr image from a cubemap. but the high float numbers get somehow cut from jit.gl.cube. Can you confirm me that?

no idea, post patch, example files, steps to repro, and expected behavior and i'll see what i can see (or email me)

Hi Rob, I sent you an email, thanks a lot.
