I created a UTextureRenderTarget2D object by code and passed it through Niagara’s API SetVariableTextureRenderTarget to the FX. I want to read the data through Grid2dCollection. I binded the rendertarget to grid like below.
and I read data
But, something maybe wrong, I always get zero result, I just searched google and the Epic’s content samples, still can not find how to read the Render Target in Niagara, but some teaches how to write.
Anyone knows? Many thanks in advance
