Is it possible to shoot a scene in isometric? Well at least no perspective to be able to set up an isometric view? I've been looking into octane a bit more as a possible use for an exploded view of an item that I am doing and I would like to make it more traditional looking in terms of how these drawings are made which is usually isometric. I went through the manual and I could not find anything about setting up the camera to get rid of perspective.
- Am I just unlucky and would have to wait for a new beta release/official release for this feature?
Isometric view?

Hi RealityFox,
Sorry, no, there is currently no camera mode for isometric or orthographic. However i believe you can get almost isometric by changing the fov to 1 and setting the camera position to x=y=z ie: 100,100,100 or whatever value suits the size of your scene. (This is with a camera target of 0,0,0). Would this be more like what you are after?
Cheers
Chris.

Yah that seems to work for the most part. Now I have an issue that if I zoom out a little bit farther my mesh develops triangular streaks in the mesh (and there are no triangles in it) now is isn't a quad, it has more than 4 points but it's just a simple flat shape so does that still cause issues?
- Also will an isometric view ever be put into octane? It would be quite useful for technical illustration.

Hi RealityFox,
You might be coming across problems of scale. Octane deals in triangles and if your mesh is showing fine zoomed in the it is not likely to be a geometry problem.
For the scale problems try adjusting the ray epsilon in the kernel settings. Also check the scale of your geometry. Sometimes during the transfer from 3d host to octane there can be change of sca;e factor of 10,100,1000 etc. Use the deep channel kernel in z-depth mode and use the z-depth-max slider to get a general idea of the scale of the scene, also taking a look at the camera position and target numbers is helpful here.
One unit in octane should be 1m in the scene. If you are dealing with extremely small items this can also be a problem so increasing the scale by a factor of 10 can help.
To change the scene scale on import you can go to file->preferences->OBJ mesh import and change the scale setting at the bottom.
Unfortunately these problems occur due to the inherent imprecision of floating point numbers.
As for an orthographic camera this is something that the dev's have talked about so i can see it happening in the future, perhaps in a 1.x release but we don't have any concrete plans for it so i can't give you a definitive answer sorry.
Hope that helps.
Cheers

Well lucky for me this object isn't really anything too important but if I have this issue again I'll be sure to check if that helps. Thanks for the troubleshoot!
- Ah well, I really hope they get it in a the 1.x release. I'm pretty sure I'm going to buy octane fairly soon since I enjoy using it so far and I could use it for oblique/isometric 3d I would be one happy technical student
