Blender Git Loki

Merge branch 'blender2.8' into greasepencil-object

Rename of modifiers completed

Now the old Dupli modifier is named Array and Array named Dupli

Before to swap array and dupli names

It's more logic to name Array the modifier called Dupli, so I'm going to swap the names

Custom shaders for drawing strand selection.

Eevee: SSR: Add two hit option.

This option add another raytrace per pixel, clearing some noise.
But multiplying the raytrace cost.

Eevee: SSR: Fix Opengl Render.

Add a constant number of 4 drawing loop to accumulate 4 "bounce" of light in SSRs.

Eevee: SSR: Fixed problem with un-initialized texture.

Also add another debug buffer and cleanup in effect_ssr_frag.glsl

Eevee: SSR: Small fixes

- Encode normals for other opaque bsdf so they are not rejected by the normal facing test.
- Early out non reflective surfaces.
- Add small offset to raytrace to avoid self intersection.
- Fix fallback probes not appearing.

Eevee: SSR: Add Weight Normalization option.

Eevee: SSR: Add View Facing fadeout.

Also make hit boolean depends on hit coord not on pdf.

Added weighted normal modifier.

Has a weight int which specifies the weights with which face area/corner angle will be exponentially divided. Threshold provides the limit in values which will be weighted equally.

Basic drawing code for hair edit mode in the new 2.8 draw engine system.

added the color lock in vertex paint

Cleanup: Fix typo error

WIP: New Duplication modifier

This modifer works similar to use dupliobjects for the current GP object.

Still pending apply button.

Topograb: Tried changing normal for correct grab position. It has become unstable to some extend and crashes a bit in some case. Still works fine in normal mode

Eevee: SSR: Add fullscreen raytrace option and Screen border factor.

Eevee: SSR: Use noise to dither the stride banding.

Eevee: SSR: Add stride and thickness parameters.

Also polished the raytracing algorithm.

Tint modifier: Create colors in new palette
