Irrlicht Engine

I guess it's the first line in here... Material mat = test.GetMaterial(0); mat.Texture1 = Driver.GetTexture("alice_d.png"); mat.Texture2 = Driver.GetTexture("alice_n.png"); mat.MaterialType = Mater.MaterialType; You work on local copy of the Material, isn't it? I'm just guessing ...

One can align tangents in the pixel shader along uv axes using the built-in functions ddx, ddx (Cg) or dFdx, dFdy (GLSL). These functions alow for calculation of partial derivatives in terms of screen coordinates x and y. This way you don't need to pass neighbouring verts/uv's... I just tried that b...

You definitely need to align the tangents along u and v axes, see ShaderX^5. At least this is widely accepted to give good lighting results when generating precomputed tangents. As tangent space is local to each face, and in order to get a correlation between all local texture space coordinate syste...

Ok, i fixed that transformation problem just by adding a 'setRotation(vector3df(RotX, RotY, 0));' to my camera animation code. The usual behavior is to just construct a temporary rotation matrix and update camera position and target accordingly. The position of the ICameraSceneNode was updated too (...

In order to get this code working with Irrlicht 1.3 i replaced OnPreRender() with the new method called OnRegisterSceneNode() (instead of OnAnimate() which actually isn't meant to be used for registering scene nodes for rendering anyways) and the code at least works. Allthough i am using my own ICam...

you also need to add

to IVideoDriver.h around line 163.

Hi, for those interested, i've recently updated to Irrlicht 1.3 (svn rev 574) and therefore needed to update my patch-set. One of the patches i use deals with rendering to multiple output windows when using Open GL. Please find the patch below: diff -uBb -x .cbp Irrlicht.svn/CNullDriver.cpp Irrlicht...
