I was working with a material of Volume domain , and had already set the mode to Additive.
I found that if I direcetly connect TextureSample’s output pin to Albedo , the material won’t calculate the whole texture ,conversely , outputs a kind of pure color such as white , or grey , or yellow , or green.
It seems that it can only take in Constant3Vector .( While there’s a lot of ‘constant3vector’ contained in a texture map)
But what causes this ?
I found that if I use 3D Texture , or place a WorldPosition node to breed a Re-mapping , the texture I used can only be correct.
I had been puzzled by this strange problem a lot , so could you tell me why a directly-connected texture sample doesn’t work?
