Apply shadow only to the naturally lit part of the fragment color (#11722)

2021-10-31T18:18:30+00:00

Fragment color for nodes is now calculated from: * Texture color, highlighted by artificial light if present (light color conveyed via vertex color). * Texture color highlighted by natural light (conveyed via vertex color) filtered by shadow. * Reflected day/moonlight filtered by shadow (color and intensity), assuming some portion of the light is directly reflected from the materials.

Fix GLES2 discard behaviour (texture transparency)

Distribute shadow map update over multiple frames to reduce stutter (#11422)

2021-07-25T10:36:23+00:00

Reduces stutter and freezes when playing. * Maintains double SM and SM Color textures * Light frustum update triggers incremental generation of shadow map into secondary 'future' textures. * Every incremental update renders a portion of the shadow draw list (split equally). * After defined number of frames (currently, 4), 'future' and 'current' textures are swapped, and DirectionalLight 'commits' the new frustum to use when rendering shadows on screen.

Add smooth light-shadow transition at noon (#11430)

2021-07-25T10:35:12+00:00

Node faces with normals pointing East/West (+X/-X) will transition between light and shadow at noon. This code makes the transition smooth.

Improve shadow rendering with non-default camera FOV (#11385)

2021-07-11T15:15:19+00:00

* Adjust minimum filter radius for perspective * Expand shadow frustum when camera FOV changes, reuse FOV distance adjustment from numeric.cpp * Read shadow_soft_radius setting as float * Use adaptive filter radius to accomodate for PSM distortion * Adjust filter radius for texture resolution

Fix swapped vertex colors on GLES2

Use vec4 for varTexCoord in interlaced shader (#11004)

2021-03-01T12:37:32+00:00

Somewhen in the past, inTexCoord0 was a vec2. Now, it is a vec4.
