simsilica/simfx

Game effects library.

SimFX

General video game effects packaged in jMonkeyEngine friendly components.

Currently includes:

LightingState

A jMonkeyEngine AppState that manages a DirectionalLight and AmbientLight making the parameters easily available to the rest of the game.

SkyState

Includes related shaders and a TruncatedDome mesh. This is an AppState that allows a game to easily include a sky based on atmospheric scattering. An optional ground plane can be included and there are lighting shaders that include atmospheric scattering that your own terrain and models can use. The atmospheric scattering code is also separated into shader libraries that can be included in other shaders.

simfx's Issues

'varying' is deprecated, use 'in/out' instead

Hi

I am getting shader compilation error: 'varying' is deprecated, use 'in/out' instead when using drop shadow filter on Windows 11 with both intel and nvidia GPUs.

Changing GLS version to 120 in below line fixed it.

SimFX/src/main/resources/MatDefs/shadow/Shadows.j3md

Line 18 in f39387f

FragmentShader GLSL130: MatDefs/shadow/Shadows.frag

DropShadowFilter does not work with InstancedGeometry

Hi,

For instanced geometries, no shadow is rendered under the objects.

in the below line

SimFX/src/main/java/com/simsilica/fx/shadow/DropShadowFilter.java

Lines 269 to 271 in f39387f

	for( int i = 0; i < size; i++ ) {
	Geometry g = casters.get(i);

perhaps we should check if the geometry is an InstancedGeometry and then check its instance list as well.

if (g instanceof InstancedGeometry ig) {
     for (Geometry instance : ig.getGeometries()) {
          // process instance 
     }
}
