Hello guys I have asked about this problem earlier (point light and shadows = too many draw calls). I have been told about something like “cube algorythm” or whatever and that it is just supposed to cause lot of draw calls. I understood that it would need 6 draw calls per mesh (as cube has 6 sides) but as I dig deeper I noticed that it causes LOT more.
In my actual experiemt I had my scene WITHOUT any shadows = 43 draw calls.
Then I added one MESH as a shadowcaster for my light and it rised to 65 draw calls, adding 2 more meshes caused rise to 100 draw calls and it continued this way.
It seems like that every mesh added as shadowCaster increases drawCalls by like 15 - 20 and it has disastrous impact onto performance.
My question is simple, is it as it supposed to be ? I can live with that and only allow shadows on full-blown desktop PCs, but if there is something I can do with it, I would like to. Sadly 3 shadow-casting meshes at this momemt causes as many drawCalls as my whole scene
Note: I only add these meshes as shadowCasters to ONE LIGHT (there are another lights on the scene, but I add meshes to only this one).
Thanx too much for some answer and if it is absolutely clearly ok, then please delete this topic as I feel like I am spamming this forum way too much :))
