How can I add a 2D image heatmap on a 3D surface from a specific perspective?
What I did now is that I roughly looked where the heatmap is drawn on the image (left) and texture paint it on the 3d model (right) by hand. That is a way to do it but not really exact and a lot of guess work.
What I want to know is if there is a way to exactly draw/map the 2D Image of the heatmap (left) on the 3d model(right)?
Maybe by aligning the exact perspective of where the camera was standing? But I don't know where to start. I'm new to Blender.
