Problem with normal map
show user profile  Braum
My high poly cave is 10 million and low poly is 10k polys. Now, problem is it's inside the cave. May be thats why Xnormal isn't creating normal map? (Creating but, it's not working in maya, I can see the same low poly version there. No projection of high poly normal map)

Please help me to create normal map of it in Xnormal.
Thank you

Flip your faces and bake your cave inside out, then flip the green channel. Probably an easier way but that's what I'd do.

edit - ps, that's without seeing what your cave looks like since your photobucket pic's dead.

Hey bro,
I flipped it in Zbrush and tried to create normal map again. But, it didn't work, though it worked with other models. I dunno why and also what did you mean by green channel?
I have uploaded cave photo in google drive. After flipping it should work, but it didn't.
So, my final solution was decimation to lower poly and paint it in substance painter. :(
Thank you for your reply

Firstly, not your bro.

Now that that's out the way, I won't be clicking on any links, a pic is worth a thousand words, I suggest you get the photobucket pic working as I'm shooting in the dark. If you're having normal map issues you can break your uv's more and bake each part separately, which is time consuming but worth it. Secondly you can adjust the scale of your obj's in xnormal, crank them from 1.000 to 100 (for both high and low poly versions), that'll help. Lastly, if you're still having baking issues you can create a projection cage in max and use that to help xnormal calculate (though I've never done that, never needed to).

As for why I said to flip the green channel if you've inverted your cave, that's just to make the vertical bump info get reversed to counter flipping it in the first place.
