I have a question about render targets and draw calls. I have a clear scene that includes only loaded meshes and materials. And i pay attention that i have too much draw calls. When i use:
scene.renderTargetsEnabled = false
Draw calls was reduced in 3 times. But i hadn’t any reflection probes/rendering pipelines/volumetric postprocesses etc. In my scene.
The post process will also require a render target and the draw calls associated.
Reducing their numbers would often be related to merging meshes and so on. Disabling RTTs only will force you to disable any associated features where the draw calls are required.
