I want to create a lua for an infernus shader / FX, can someone help me or guide me to do it?, It is usually called "Dynamic Vehicle Overlay". i have the FX, just need to add the commands. I know it adds: dxSetShaderValue (Shader, tex, Texture) But i don't understand.

Hola, queria saber si alguien me puede facilitar la informacion de como crear una textura y ponersela a un objeto usando shaders. Seria de micho ayuda. Tambien me serviria alguna miniguia de fx que anduve jugando con eso y solo logre cambiar los float de los colores. Gracias de antemano!

Hi, I was wondering if any of you could give me some advice or some information about shaders and how they work, and also if its possible, with .png, create some textures for the game and dont remplacing any of them at all. It really would be very useful to me, because on my own I only could make some shaders that change the colors of the screen at that's all. Thank you!

Is there a way to morph a part of an object with a shader like pedmorph? So I don't want to morph the whole model, just a part of it. (Like a ped's head, or something)

I just want to make shadows in MTA, like in this video: (at 2:33) There is a dynamic light shader with shadows, but it has so many bugs.

How can i just apply the same shader to the same texture twice? I want to make a car vinyl system, but the last shader i've created overwrites the others. Any idea?

Hi! I just searched for lighting effects, and i found a shader for XNA. Its an Ambient and Diffuse lighting shader with Shadow Maps: #define GENERATE_NORMALS #include "mta-helper.fx" //------------------------------------------------------------------------------ // File: BasicRender.fx // // Copyright (c) Microsoft Corporation.

The diffuse and the ambient light works correctly, but not generating shadows. Any Idea?
