Maybe I have to #include <mtlFX.c> into my project, but then how I will assign mtlFX shader actions to the entities in my level? And the engine always can't find the mtlFX.c which is in the folder. It is a little confusing so can you tell me how to use it or give me a sample plz

Every shader which comes with 3DGS has a material which CONTAINS the shader information. So if you want to add a certain shader to a model, you just have to assign the shader to it. Example: Code: action myEntityAction(){ my.material = mtl_toon; } This would cause the entity which uses the action "myEntityAction" to be toon-shaded. Basically it is that simple, but certain Shaders (phong shading, water shading etc.) have special requirements. To inform yourself about these and to get a full list of all shaders, visit: http://manual.3dgamestudio.net/acknex.htm Oh, one more thing: these shaders work only with 3DGS 7 Commercial or above. There are some fixed-pipeline-shaders which will work with ALL versions of 3DGS (including the free version), they can be found in the GameStudio Wiki. Hope this helps. Alan

But when I try to compile I always get this error Help plz
