Projection mapping on LED Wall

Hi,

We have a curve LED wall & LED floor for virtual production.

I would like to check if there's any simple projection mapping in Aximmetry that we could use to playback normal 2D video or images for presentation on the wall when not using Unreal?

Hi,

There are several ways to accomplish this, but the simplest method is to project the video onto a sphere and render it for the LED Wall. This approach is discussed in detail here: https://my.aximmetry.com/post/2527-360-degree-video-on-led-wall
If you are not using a 360-degree image or video, you probably want to use the Basic shader ([Common]:Shaders\Standard\Basic.xshad) instead of the Skybox_Long-Lat shader. Then, you can adjust the position of the video by modifying the Tex Coord Transf pin. Start by increasing the scale of the Tex Coord Transf pin, which will cause the video to appear multiple times on the geometry. Then, adjust the position to ensure it appears correctly on both LED Walls.

Note, don't worry about the video appearing multiple times on the geometry of the sphere; it will not decrease performance.

Warmest regards,
