This is an attempt at producing an exhaustive list of useful Mrl3 Materials and how to control their properties. This is not a formal repository or compendium of them but a "useful Mrl3 and Materials to know about".

(thanks to Aragaki)

• Unknown 2 and 5 control the transparency values.
• Unknown 2 closer to 0 for more tolerance for transparency (higher values will have alpha 0 be more solid until alpha becomes nonexistant).
• Unknown 5 on values 4 to 7 control for it to be gradual and not binary transparency.

Reference Image on the Editor

0 = 100% transparent

(thanks to NackDN)

• Tested in material b3f9350a:44f2f535 (the general weapon material)
• Set unknown 2 to "0," unknown 3 to "112," and unknown 4 to "1," as well as the Surface Direction to 1101 to achieve ditherless transparency

Transparency With Dithering

Transparency Without Dithering

(Thanks to Statyk, Silvris and NackDN) In the XM:

• bUseWaveEmit - Swaps the emissive breathing to waving, still uses other emit options.
• fAnimEmitWave - Number of waves per UV space. Higher numbers mean more waviness
• fAnimEmitMin - Lowest brightness in the darker pert of the blue channels, similar to the breathing
• fAnimEmitSpeed - Speed of waves going across

In the MRL3:

• fRefractBlend__uiUNorm - Setting for enabling/disabling the panorama. Not too sure about fRefraction but they're right on top of "fPanoramaTile" so I think it might be mislabeled.

• Tested on standard weapon materials.

The Waterfall Trick
(First discovered by Jodo, used by Fabaji, documentation thanks to Asterisk)
974599c3:e1b22780

• tFlowMap: Controls application of "waves".
• tAlbedoMap: The Diffuse.
• tNormalMap: NormalMap (the big "waves" gloss).
• tEmissiveMap: Applies a tint, water has a natural glow/reflection.
• tRMTMap: The RMT map (Metallic, Glossy, etc) [Untested].
• tDetailNormalMap: The normal of the finer details (sand/rock like looking things).
• tCubeMap: Lookup CubeMap in wikipedia.
• tAlphaMap: Partially controls alpha but also relates to the secondary parameters.
• SS: Do Not Touch This, This are samplers they aren't actually taking a texture.

(tFlowMap)

• FlowStr: How much the Flow Map deforms the base texture
• FlowSpeed: How fast this deformation animates (Deformation animates from white to black)
  The deformation is the aplication of light and shadow simulating "waves". This are taken from the SS texture maps. Both green and red channels each correspond to a wave generator. Black is strong source and white is almost no movement/waves.

• UVTransformA: How much the colour of the Albedo of the texture mapped to UV1 is visible as applied to the texture.
• UVTransformA: How much the colour of the SS? of the texture mapped to UV2 is visible as applied to the texture.
  Raise the values so your albedo is more or less visible (on its specific channels) otherwise it will be washed out with the colour of water.

EmissiveMap only tints, water naturally glows.
Base Factor filters the colours, but the UVTransform determines how they blend with the base material (overpower or act underneath).

Note that even if the colours aren't visible they ARE visible when the light shines through (noticeable with rainbow tinting for example).

• UVOffsetSpeedFactor. First value is horizontal scroll of the uv map for the albedo, goes from left to right. Second value is vertical scroll, from bottom to top.
• UVOffsetSpeedFactorDetail. No clue what this does. Tested somewhat extensively mixing it with other parameters but might have been lost because most of the mrl3 was deactivated for testing.

The Glass Material
(First discovered by asdasdasd, brought to attention as a glass candidate by Silvris. Experimented on by Asterisk and Documentation made by Akko with editing by Asterisk.)
vfx/mod/cm/md_etc/md_cm_awa000/md_cm_awa000.mrl3
b5a8acc8:b79217f8

• tDisplacementMap
• tAlbedoMap: The Diffuse (Must be enabled on the default version)
• tNormalMap: The Normal Map, requires a visible diffuse to show up
• tCubeMap: A Cube Map (Lookup wikipedia)
• tFlowMap
