Hi there! I’m making a 3D platformer for PC and I’d like it to compatible with mobile devices too. I’ve made a lot of rock models in Blender and imported 'em into Unity and everything is fine. But now I’m thinking if 3k polygons (average) for every rock is a bit to much… (I’ve just started to build my level and there is no a lot of rocks for now (about 30)).
So, the question is: 3k polygons for every rock is too much?
yes it is so much you can use unity cruncher plugin or other retopolgy softwares to turn
your high poly to low poly , or you can do it yourself ,follow this tutorial
‘Sculpt and Retopologize’ is a good workflow to get your head around generally. Basically start with a very high poly model and then use whatever the equivalent of 3dsMax’s Freeform tools are in Blender to create a matching low-poly cage over the top. This video seems to explain the basic idea pretty well.
