Add rendertarget to rendertarget
I would like to add a rendertarget incrementally to another rendertarget ("rendertarget A" x 0.001 + "rendertarget B" = "rendertarget C") with a function in BP. What is the best way to do that?
So far I tried to connect "rendertarget A" followed by a multiply to the emission slot of an additive material and use a function to "Draw Material to Render Target" to create "rendertarget C", but the values seem to clip to black at these small values and "rendertarget C" renders black..
Any idea? is there maybe an easy c++ solution for this to combine textures?
Thanks a lot for any help! Cheers, Toby
