Hi everybody, I am new to vfx and I am trying to understand optimization techniques for particle systems in Niagara.
I have some water splashes and I am checking the impact they have in the shader complexity view. If I use a translucent lit material the impact is absolutely terrible, I can make that a bit more performant by changing the material to unlit but it is not a radical change for the better.
The best option for performance seems to be to use an unlit masked materials but that is terrible for how the effect actually looks as the masked material does not do opacity fades but hard cutouts.
ISSUE 1:
I am not happy with how the splash looks when changing the material to masked and it also introdues some weird shadow artifacts. I disabled shadows in the material and in Niagara, including any lumen related shadows but the artifacts remain.
ISSUE 2 :
Performance-wise I know that I can try to optimize the material, I know I can use cutout textures in the particle system and I know I can make my particle system GPU based. Are there any resources you can recommend to learn more about optimization? It is hard to find good information in this topic.
