i'm not 100% sure this is a bug. here we go :
hlsl vertex shader :
works ok:
if replaced by this, it freezes the computer, you have to press the reset button, you can't use the keyboard or mouse at all :
Code: Select all
Out.Pos = normalize(Out.Pos)*createwave2(Out.Pos);

i think this happens because Out.Pos can be (0,0,0) which cannot be normalized BUT i don't think that this should lead to a frozen PC.

Double check your drivers, since the shaders run on the card. Irrlicht just uses the DirectX or OpenGL calls to upload the shader.

discard the issue and lock the topic. normalize was working on Out.Pos which is a float4, .w being always =1 but with normalize() it changes so it crashes. some times i should think before i post.
