Irrlicht Engine

I finally had chance to dig into the GouraudShading flag. In OpenGL, it results in a toggle between glShadeModel(GL_SMOOTH) and glShadeModel(GL_FLAT). So it's not a shader program thing fortunately!

I am using Crocotile3D and the only option I have is "Lambert" and "Phong". I don't know how that makes it into the Collada file exactly. I'd never heard of Lambert before so I don't know how that differs Gouraud, I need to do more research. Maybe some kind of warning that Lambert doesn't work ...

Oh man that was it!!! Thank you so much, my level looks SO much better.

Where are these shaders stored? I know nothing about the old shader assembly but it sounds interesting. Would it make sense for Irrlicht to force gouraud whenever lighting is enabled or is there still a use case for the current ...

D3D9 gave the same result. I played with the code you provided and I am also seeing weirdness but it's also kind of similar to the issues I am getting with vertex shading. It's shading one side differently than the other....

Thanks for the input, I will poke around. I don't have D3D SDK installed so I can't try D3D9 right now but it's interesting that Burning's renderer does not show this issue.

Hi, I am having a problem where half of a square is being lit differently than the other half. I'm not sure where to start tracking this down. Moving around the scene there are positions where everything looks okay then others like in the screenshot below is not great. I am using revision 6438 from ...
