Cube Map issue

[NeonsStyle]

Hey,

 

I'm trying to make a cube map, and the images from envshot <filename> size (512) are always coming up mostly black. Why is that?

Set your screen resolution to 640x480

@nbohr, Im sure you are Steve have mentioned this already - but does env_shot now work correctly in 2.04..? and if yes have the instructions on the wiki been updated..?

[nbohr1more]

There are two envshot methods.

 

Regular envshot produces images with _up, _down, etc per the cubemap wiki. You need to use cameraCubeMap for these. You need to be at 640x480 to collect the images.

 

The new envshotGL in SVN/2.05 (and the cubicLight beta) has the old _nx, px, etc naming conventions and orientations. These are used

for shader development but also can be used for some reflection effects where texgen reflect is called. Still need to be at 640x480.

I had wanted to to create inside and outside cubemap's for the windows in Sir Talbots but gave up. What version would it be easier to do this in 2.04 or wait for 2.05?

[nbohr1more]

The regular envshot in 2.04 should work for that.

 

If you want it to look like a reflection, then take the screen envshot outside facing the window and use

 

cameraCubeMap /env/root_name_of_images

 

texgen reflect

 

in your material.

 

If you want to simulate the interior (interior mapping) of a room, go into the room and face the window

when you collect the envshot and use cameraCubeMap and texgen reflect as above.

I'm actually trying to make a floor panel look 3 dimensional. I had it set to 640 x 400, but most images just came out black or partial black, and were not usable.

The envshot command is designed to collect the environment. To make your scenario works, you will need to enlarge your tile to gigantic proportions

then collected your envshot from inside the tile and finally shrink the result with scale args. I wonder if setting an alternate FOV might be used to do

this instead of needing the giant version of the tile? Or, since you are using cameraCubeMap, just make custom versions of the texture images that represent

the up\down\left\right\forward\backward views you want to represent as the interior, they should all be flat anyway.

I already made a giant version of the tile, and envshot it from inside the tile, with the floor surface above me. I think I have it sorted now, I'm

getting good pics, now I have to learn how to use it.
