werner.poetzelberger Posted October 28, 2014 Share Posted October 28, 2014 Hello, We create a camera in 3dsmax and want it 1:1 in Unigine. I have brought it that far, that I have the same settings for FOV and the Lens. So the perspective seems to be the same, in max and Unigine. I also set the Image output in 3dsmax to 2560x1600 and the render size in Unigine to 2560x1600. The result is, that I get a much bigger view in Unigine. Can somebody help me to find the difference. Settings in 3dsmax: Camera: Lens 36,102 mm Camera: FOV (Horizontal) 53 mm Rendersettings: Image size 2560x1600 (1,6 aspect ratio) Aperture Width (mm) 36 mm Unigine: Camera FOV : 53 degrees Camera Lens: 36,102 mm Render output 2560x1600 px Image difference, see attached image: The center is the image from 3dsmax viewport, overlayed to the Unigine viewport.

werner.poetzelberger Posted October 28, 2014 Author Share Posted October 28, 2014 Ok. We found out, that multiplying the projection matrix with a factor (in our case something around 1,60), matches it pretty exactly. Nice. Would be interesting where this differences come from (I blame it first of all on 3dsmax hehe). Cheers. Werner Link to comment
ulf.schroeter Posted October 28, 2014 Share Posted October 28, 2014 2560 / 1600 = ...... guess what ? 1.6 Link to comment
ulf.schroeter Posted October 28, 2014 Share Posted October 28, 2014 window aspect ratio is part of the Unigine internal calculations when you specify camera fov Link to comment
