Unit Wonder!!

1 unit in b3d is what size in reality. 1 meter, 1 feet, 1 milimeter or 1 miles?

Don't say that its up to me, because its look like the light and camera has preset scale of calculation.

I create one room 3 meter x 3 meter. Because I assume i unit is 1 mm so my room is 3000 x 3000 unit size. Then I create point light on the centre. In b3d my room is so dark.

Then I change my unit. I asume 1 unit on my 3d is equal to 1 meter. So I create a room size 3 x 3 unit. Create a pointlight and render in b3d. Its to bright ???

So what unit we should do?

size is irrelevant. 3000x3000 is WAY too huge, you shoulc be trying to keepm the scale smaller. Anywho the light wasnt illuminating anything becase it has a default max range of 1000 (Units radius). Decide what each unit means for you. I personally use 1 meter = 1 blitz unit.

At the standard FOV on a 17" monitor, you have to scale the camera by 0.05 on all 3 axii, for 1 unit to equal 1 meter.

1 unit to 1 meter is a common setup.

What MB said.

What Mustang said.

Yeah, one metre in Lightwave seems to end up as one unit in Blitz3D.

But then consider sound. in order to get 3D sound working properly if you are using too large of a scale you never hear the sound until the listener is in range of the sound.
I think the smaller the scale the better but if it's too small then you deal with floating point errors. I started my game with 1 unit = 1" so I have to scale things down to get lightmapping to work. I would think 1 unit = 1' or 10' would work for a fps maybe 1 unit = 100' for a flight sim
but then again ditto to what Ross C said

Thanks a lot guys..
