Thanks, I solved it with your help.

@LazyGunner You can just use TextEditor to open the USDA file. Find the following code 👇, delete it, and save the file. Then try importing it into Reality Composer Pro again. ''' def DomeLight "env_light" { float inputs:intensity = 1 asset inputs:texture:file = @./textures/color_121212.hdr@ float3 xformOp:rotateXYZ = (90, -0, 90) uniform token[] xformOpOrder = ["xformOp:rotateXYZ"] } '''
