SpencerL Posted November 12, 2007 Share Posted November 12, 2007 Hi, This seems to be something fairly straight forward but am having problems trying to figure it out. I am trying to convert the position of points in uv space to their world space location. Any suggestions would be great! Thanks Quote Link to comment Share on other sites More sharing options...

Otherwise, depending on the UV projection, it might be pretty tricky to invert the transform. For example, if the UVs were edited by hand, it wouldn't be possible at all (I think).

No, I am not looking for NDC space. This isnt for rendering purposes. Basically, I have a curve that is snaped to the surface of an animated model/geo. I need to deform this curve so that each point always remains on the surface of the animated model. Thanks Quote Link to comment Share on other sites More sharing options...

sibarrick Posted November 12, 2007 Share Posted November 12, 2007 (edited) Sticky object and make your curve at object level? or just object merge them and make your curve out of the points using an add sop Edited November 12, 2007 by sibarrick Quote Link to comment Share on other sites More sharing options...
