Just because it doesn't, or it does only for a 4/3 image ratio

For example, a 1920 x 1080 (16/9) image with a 24mn camera corresponds to 45,483616 deg
That's not so trivial ...

in fact full frame cameras have a 4:3 sensor.
vray camera has more controls like the image aspect ratio.

full frame is 36mm x 24mm so it's a 3:2 senzor.

Those camera angles would be a nice feature, since I didn't realise the corelation of fov to camera lens angle also...

Btw - did anone try the new perspective match in max 2014, is it working as advertised in octane environment?

I have a wall with a diffuse material on it with a blank diffuse color and a texture in the opacity channel that makes slats (which let sunlight come through and hit my objects).

There is no problem except when I make the diffuse color perfect black. In the picture with the bright lines on the object (#1), the diffuse color is just 0.001 brightness above black, but it works perfectly. The one with the low contrast lines (#2) is when the diffuse color is exactly black. I find it especially weird that the light coming through from the slats is the same brightness, even though the object is experiencing a different light.

I am rendering in DL kernel.

Now this isn't something that's holding me back from my work, especially since the workaround is extremely easy and has no negative effects... but it is something that maybe needs to be addressed.

WOW I rendered it in PMC just to see if that would make a difference... WELL IT DID. but not quite in the way I was expecting...

Post-processing doesn't work, and the exposure is blown out by 50x (had to go from exposure 50 down to 1 to get a proper exposure, and it ended up still looking messed up like the last post, but still without post processing).

Upon further inspection, I realized the problem was with the rest of the box. All the walls/floor/ceiling have the same material except for the one with the slits. The wall texture, when pure black, created these issues, but when making the wall with the slits pure black, the same problem did not happen. The cube has it's own unique material too which is just a white diffuse.

Hi, karba I need help urgent,
My system was working perfectly and since yesterday I have a problem with my system 1 gtx 580 3 gtx 590 (6gpu) total 7 are gpus, gtx 580 is the principal card 3000 ram, when I start the viewport is as if it blocked the first 30 seconds I can not do anything, then starts working fine but slow and sometimes crashes, if the disable and work only with the 6 590 gpu I can move the viewport very fluid, also when working with 7 580 gps but I put it on low priority.

No problem for sli
The system does not install or change anything

Help please

Thanks

Do you use sli option (multi GPU mode enable)?

No use sli and I chek the drives have beta 320 put the 314.22 and nothing. Change the version to 1.1 and nothing an I use the max 2014 change to 2012 and nothing. I use windows 8 32 gb ram. Check bios and nothing.

@karba

is it possible when you isolate an object to have at least the sun not to hide ? I do a lot of exterior archviz, and everytime i isolate something, it all hoes to black
This option is available in vray as i know.
thanks
