So i’m new and still trying to understand how things figure into what. I did an experiment and I used the foliage tool to drop 2k of rocks with a small radius around my character, the rocks used default material they came with and to my amazement I was hitting 65fps. I then cleared them out, I changed the material on the rocks to one from another pack I’d bought and did the same dropping 2k rocks in my vicinity, with the new material I was hitting as low as 30fps.
So my question is, what exactly is it with materials that causes this kind of performance drop? I keep hearing people talking about shaders, talking about LODS and other stuff. What is it I should be looking out for to try and keep the materials looking decent but not too taxing on the playability?
