Welcome to TVPaint Community forums !

I used to Work on small Document Size like 1080P or 72DPI, but now I've been working on Large Posters and my drawing size has increase greatly. I now work 4K Resolution or 350DPI Images Large Poster Size for Prints. But now the Max Size of Optical Flow 1000 is too small. Is there a way to increase to 3000 to 4000, I'm not really sure but maybe 6000? At 1000 Size of Optical Flow in 1080P it doesn't cover the whole document so I guess it's pretty small. I guess the biggest document size I'll be working would probably be 6667×9466. I guess the cover area I need to it to be would be the same as 1080P at the Optical Flow Size of 1000 but at 6667×9466 size.

I think TVPaint,well TVPaint 11, also freezes at 6667×9466 starting up Optical Flow.

- You are not restricted to any preset dimensions. During startup, just type in the dimensions you need.

- TVP starts easily with a project of 10.000 x 10.000 px. I found, however, that trying to create such a projct while TVP is already open with another project might cause a crash.

And optical flow is a very greedy fx. If your computer is not powerful enough, a crash can occur.
