Shader Effects

[reepblue]

Josh and I were talking about effects that should be part of the default shaders. I'm making a list here.

1. Simple UV manipulation:
   • Rotation - I should be able to simply spin a material from the center or a defined position in the UV.
   • Scrolling - For conveyer belts and such. I might also use this for my fizzler.
2. Animation with a volume texture.
   • All texture sheets should cycle its frames unless the sheet doesn't have any additional frames.
   • If possible, maybe allow for each sheet to have its own animation speed defined in the material? If not, one speed value for the entire material is fine.
   • If no speed is defined, it should animate at 60fps automatically. 
3. Emission Color Modification.
   • In Cyclone, I created a shader that piped the entity's color to the emission mask instead of the diffuse texture and it worked out really well. I just had to change the entity's color in code to make something glow a different color. I'd like to be able to do something like this in Ultra Engine.
   • Alternatively, if a model can have multiple material variants (i.e Skins), I can just swap the skin instead. In my opinion, implementing this would have much more use cases than allowing me to change the emission color but do what's best. Maybe both can exist? 
4. UV Tiling on decals.
   • The Decal system hasn't been started but this was also another custom shader I had to do in Cyclone. I want decals to tile their UV's like the brushes. I need this for my indicator strips.

I'm thinking per-entity settings should be emission color, texture position, texture scale, and texture rotation. Emission color is only active if an emission map is present. It does not act as an emission color alone, because otherwise it would be impossible to display many models correctly.

Animation (scrolling and rotation) should be a per-material setting.

I'm basically just describing everything in the above post using different words.

We need a kick *** ocean and water shader with waves, foam, underwater effects and caustics, etc.

Please make that a reality. I know there is already buoyancy, so great water would really help.

I agree. would be so much easier to convert Lone Water to Ultra
