== How to implement == | === reflect.eff === | ||
It all began with a simple ReflectionShader, which simply adds a spherical map on the surface of the object. This shader works on not-UVmapped surfaces. Ideal for simple chrome parts. | |||
'''Example Aircraft:''' B29 | |||
=== reflect-bump-spec.eff === | |||
Later it had been enhanced by a [[Howto: Use the normal map effect in aircraft|Normalmap]]. This makes the surface appear "bumpy" depending on the used normalmap. The alpha channel of the normalmal also defines the specularity of the surface. This shader works only on UVmapped surfaces! | |||
'''Example aircraft:''' c172p | |||
=== model-combined-deferred.eff and model-transparent.eff === | |||
This shaders had been enhanced even more. You have now: reflections, normalmap and specularity map, lightmap with 4 simulated lights per object in Default and Rembrandt. In ALS you will get also a grain/ rain effect and the darkmap. This shader works only on UVmapped surfaces! | |||
The model-transparent.eff is used for transparent objects which represents transparent surfaces like glass, propdiscs.... | |||
'''Example Aircraft:''' EC 130 B4, EC 135 P2 | |||
=== What will be reflected on the surfaces? === | |||
All of these effect uses Cubemaps and Cubecrosses from data/Aircraft/Generic/Effects which contains the image of the environment which will be visible as Reflection. Depending on which you choose, the appearance of the model will later change dramatically. | |||
