Crash on InitCustomFormat for Render Target

RTHeight1 = NewObject(this, FName(“RTHeight1”));
RTHeight1->InitCustomFormat(FFTMapWidth, FFTMapHeight, EPixelFormat::PF_A32B32G32R32F, false);

Maybe format is not supported? But my video card can handle that.

I decide to use render target created in Editor to be able to use 32 bits format.
