I´m getting really bad fps drop while moving the camera on the viewport since I started using grass on PCG. I have other plants on PCG too, in the same volume.
Is there a workaround about this?
Here are the steps on PCG that I´m doing
- Cover the entire terrain with the PCG volume
- Get texture sample, put it a grass mask of choice
- Put it to 64 texel size
- Project the texture points to the landscape
- Bring a density filter
- Spawn static mesh and set it to grass type
- Put culling to 10000 or so
Even if I do static shadow invalidation behavior, or turn off dynamic shadows, doesn´t matter, I get a big fps drop when moving the camera in the viewport. Although rotating the camera doesnt do that.
Any ideas?
Shall I come back to the material layered grass instead? I wanted to use some cool noise to scale the grass on PCG, but…
My project has virtual shadow maps on, I tried turning it off, no change.
