Resolved What means the "Always draw dynamic" option in update shadows in lights?

Hi,
Unity says that option makes ignore the update mode and renders shadows every frame, so what is the difference from just update mode to Always?

 

Have a look here
https://docs.unity3d.com/Packages/c...Shadows-in-HDRP.html#mixed-cached-shadow-maps

 

i read it but doesn't clarify anything, i already get dynamic objects render shadows without dynamic option. It says renders dynamic object shadows every frame but with ondemand just in moment the user request it, so it is not every frame, it is confusing. OnDemand is supposed just render it ondemand, just renders the shadow when the user request it, so don't undertand always render dynamic.

 

Ok thanks, what i don't understand is why i still see fps drop when i have shadows enabled on demand without the always render dynamic, shouldn't it be the same as having shadows disabled? as the shadows are already cached, i need to disable the light component or object or i still see fps drop

 

No, i have no other scripts changing it, i just have two spot lights and one directional, one spot light triggers shadows, and is the one which is ondemand, triggers RequestShadowMapRendering once per frame while a door is opening and then is not triggered anymore. In editor there is no fps drop but in the build i use vsync and drops frames from 90 to 45 in VR once i open the door, but doesn't happen in editor
I have to disable light after opening door completely otherwise frames drop

 

In build i see as frames pass from 90 to 45 cause vsync if i don't disable the light, in editor remains in 90fps. The problem of disabling it is that shows a very small change in lighting suddenly just for an instant that doesn't look well

 

Yes, i was making the same in other light and happened also in editor, in build must be that just drops fps for some reason, but i need to disable the hd additional light data or fps drop, that is the problem i want to solve

 

I solved it disabling the shadows, didn't know i could update with shadows disabled in the light
