Hey guys. I have a question that I couldn’t find the answer of anywhere. Sometimes an object (it was a round table in my case) matches the camera view (I am using Perspective Plotter) but when you look at the object from other views, it’s completely out of scale (Blender was telling me that on the X axis the table was almost 6 meter long, which I don’t think is the real scale of office tables.). Now, here is the problem: If I change the scale of the object on the X axis to match it with real life values, then it won’t be matching the camera view. If I don’t change it, I know it’ll look off in the final render due to light will be bouncing on more surfaces. What would be the solution for such case or what might be causing it? I’m attaching some screenshots so maybe it’d be easier to investigate this issue.
It’s always a good idea for any camera match to choose some square or circled objects to check the found camera settings…
In you case there are the table in front, the one in front of the desktop and even the basis of the seats arround you special table… the number of seats also can get you a rough idea of the ratio of this tabl… it’s two chairs on the long side and one one the shorter side…
So your estimated match… is just wrong…
