am i stupid...where do u see the framerate ? Which shaders ? I only see the portal ? I have more then 2-4 that is for sure. Edit2: Forget what i said about the camera, it was my mouse.

Edit: But the portal is cool. Really nice.

I noticed that other stuff was very slow too, a restart fixed it and it works just fine now .

@Espér :
Pro quality , very good
And the old ones are good also.

Just created a cutoutshader:

There is a cube model with the attached cutout material. It clears the given space, so the background becomes visible(by still respecting objects in front of it).

The cool thing is:
The hole, while invisible, is still color encoded. A postprocessingshader can easylly detect it:


by checking for the colorencoding, its possible to differenciate the holes during the postprocessing. Above hole just filled with red.

EDIT: i had the idea for this cutoutshader after kartoffel explained is paradox demo.

Cool. I would like to see such an cut out shader on an alpha channel of an sprite. Would be great for making damaged walls or whatever. But i dont know if this would be possible.

So easy with voxels


First retopology preview with normal map :


I could increase resolution and add lot of details, but i keep it simple

@Rackscha:

can you specify the objects wich are seeing through? Or are all objects till the skycube cuttet out?

@Gri all objects till the sky are cutted out. Otherwhise extra rendering with extra views might be required. Because the entity with the cutoutshader still write to the ZBuffer. Disabling it would result in everything overlaying the entity-hole.

EDIT: The technique behind it is pretty simple(maybe not optimal). The cutting entity just draws its colors with alpha = 0 to a 32bit rendertarget while writing to the ZBuffer.
The final composed image is manually dran to the screen(draw_quad) to respect the alpha channel

Kartoffel@ still doesn't work for me, but never mind.
Thank you guys (especially 3dgs_snake) for ignoring my messages

@3run: The effect is based on shaders. The portal does not exist if you disable shaders
