        you need have most Vram or your scene is to much complex

          so need to upgrade my vga, because my scene already simplified. or keep using cpu lightmass.
          thanks Julian Vinet.

            Finished my scene with GPU Lightmass https://www.artstation.com/artwork/v1O3OO was going to bake at 2048 but it crashed cause i forgot to increase my TDR also the jump from 1024 to 2048 bake time is long 1024 bake time was 28 hours 2048 was like 4 days and like 10 hours when it crashed. Using a RTX 2080 ti

              Also work around for cloth with 1 side face how i did it:
              ~ Bake scene with gpu lightmass.
              ~ convert back to cpu.
              ~ select the cloths and set lighting channel 1 or 2 beside 0, 0 is main scene.
              ~ make a new map and add it in the level context and setup simple lighting scene close to your scene, all light source for the cloth must be in the same light channel as cloths.
              ~ bake and adjust light intensity until its satisfying.

                  Works nicely with 4.24.0.p4. This feature is invaluable when using UE. Very very much appreciated Pax!
