Hi! I’m trying to replicate Roblox’s ThumbnailGenerator service in a game I’m working on, particularly to show a preview of the player’s avatar on the title screen similarly to RetroStudio or AWM.
I’ve been doing some tests using the March 2007 build provided by MaximumADHD, and so far this is what I’ve discovered:
- The camera angle is always either (-23.927, 26.341, 0) or (-23.927, -153.659, 0), both angles are pretty much the same but rotated 180 degrees from each other on the Y axis.
- The “Focus” CFrame is positioned directly at the center of the objects being captured, with the orientation being (0, 0, 0)
However, I can’t seem to figure out how the camera’s position works. I’ve tried a couple different things such as getting the magnitude of the object’s size or using rays to find the distance between the camera and the nearest surface, but nothing I tried seemed to give the same results as the ThumbnailGenerator’s output camera position.
Here’s some notes from a couple experiments I did using differently-sized parts:
Input Part 1:
Size: 4, 1.2, 2
Position: 0, 0, 0
Output Camera 1:
CFrame Position: -1.801, 1.801, -3.637
CFrame Orientation: -23.927, -153.659, 0
Focus Position: 0, 0, 0
Position Magnitude: 4.44015
Input Part 2:
Size: 4, 3.6, 4
Position: 0, 2, 0
Output Camera 2:
CFrame Position: -2.727, 4.727, -5.508
CFrame Orientation: -23.927, -153.659, 0
Focus Position: 0, 2, 0
Position Magnitude: 7.75365
Position Magnitude (With Y adjusted to 0): 6.72392
I rarely post here to ask for help since I either end up finding some sort of guide on the web or figure it out by myself, but I can’t seem to find anything this time around.
