Projector Calibration and Mapping in Touchdesigner

How can we set up projection mapping and calibration in TouchDesigner using multiple projectors?

I’ve seen tutorials and videos that demonstrate it with a single projector, but not with multiple ones.

In my setup, I have two projectors pointed at a relatively straight wall. They’re positioned at different angles and locations, with about 80-90% overlap in their projections. I used Kantan Mapper to align them and did some edge-to-edge mapping, but I’m not sure how to calibrate the overlapping areas to create a smooth blend. How do I achieve that?

I am using an epson eb-pu2010b projector

Hi,

You can use projectorBlend component from the palette (see the Mapping section)
You also have the Vioso TOP but it requires a third party software.
Alternatively you can do it by hand with masks
