Set up orthographic camera to render 1024x1024

[Anonymous]

I am trying to create renderings of portions of my terrain to use as a mask in a game engine. So what I want is to be able to set up several cameras to render out a 1024x1024 image of an exact portion of my model. I've been stumbling around with camera and render settings. Can someone give me a hand? Thanks.

hi, just an idea how this might work another way.

setup a plane of the size of your desired cutout, apply a projection modifier add the terrain parts to it and render the part of your terrain from 'render to texture/completemap' or whatever is suitable for you.

Hi. Lets say you'll make a 1024x1024 orthographic render of an area beeing 100m x 100m:

1) Set your render output to 1024 x 1024

2) Create a free camera and place it right in the middle of the area on x and y, and rise it to 50m on z axzis (50m = ½ of 100m)

3) Set the target distance to 50m

4) Set the FOV to 90 degree

5) Set the viewport to Camera and render

To make more areas, simply array the camera on x and y with a distance equal to the area.

Note: This will work no matter what the z value your area is. Actually your area can be above the camera as long as you render through the camera.

If this solves your problem, please mark it as "Solution". This makes it easier for orthers with the same problem to find a solution.
