3D grass problem

Recommended Posts

Hi all,

Noticed this weird grass problem on a number of my airports. For example here is a screenshort from ORBX KVUO. I get the same odd-bright grass on other add-on sceneries, like for example FlyTampa Copenhagen. Does anyone has any idea of what's the culprit behind it? Default shaders are used.

Hi,

This weird look appears when cloud "Cast Shadow" is enabled and Simulation Objects "Receive Shadow" disabled. Enabling Simulation Object to receive shadow will solves this weird look.

Thanks for the reply. Unfortunately its not HDR and its not a shadow problem. Even if I disable or enable all shadows, same appearance...

Here is all shadow off :

Here is all shadow on:

In FlyTapma Copenhagen, here is with cloud shadows enabled and Simulation Objects receive shadows:

And here is with cloud shadows disabled and Simulations Objects receive shadows.  I also get this annoying fence grass issue:

Something is certainly very wrong in my installation. Re-installed v4.3 Client, but same problem..I guess a full re-install seems the only way.

My initial reaction was that this was Speedtree, but then I assumed that the grass was custom-built for the airfield. Does it help if you turn off 3D dynamic trees?

Thanks for the reply..The speedtrees are turned off. Deleted generated folders. I think nothing is fixing this.
