Multiangle_to_normal function

Question

Hi, Apologies if this is an obvious or dumb question - I'm a but new to this and the learning curve is proving steep! I have been using the mutliangle_to_normal function in 3D Designer to take a set of images recorded using illumination form 4 equally spaced directions - lets say N, E, S and W - to create a normal map of my object and from that create a height map. It works really well and give some amazing results. But.... I now have a sample where I can't use the 4-equally spaced points, the lamps have to be placed at irregular, but well-defined, known points. Can I change the input angles into the function and if so how do I do that?

Thanks in advance, and agin aplogies if this is too easy a question.

Hello @resourceful_Lionheart2989,

Thank you for the question.

The multiangle to Normal node needs each images to have evenly spaced lighting. Therefore, if you have an irregular dataset, I'm afraid it will be complicated to get the result you need. You can try to

RMB on the Multi Angle node > Open reference > Select all > Copy paste in a new graph > Edit the graph to build your custom multi angle

That being said, it is a fairly advanced workflow.

Otherwise, I advise you to check for Substance 3D Sampler and try to put your inputs straight in Sampler. The results are usually pretty interesting.

Best regards,
